HP NAS VA
Overview
The HP Surestore Network Attached Storage (NAS) VA solution stores data on your network. NAS solutions provide a simpler, more reliabl e, and cost-effective way to add storage to your network.
The HP NAS VA solution consists of:
o A file server o One or more storage arrays o Tape library (optional) o A rack
The HP NAS VA solution offers the following features:
o An operating system optimized for storage and file serving. o The NAS web interface for device management. o Context-sensitive . o The ability to attach a storage array to your HP NAS VA server and manage that array
using the Command View SDM web interface.
o Supports the following through HP -UX:
o SNMP notification of critical events o Remote system log (syslog) capabilities o Snapshots for quick retrieval of data that is inadvertently lost or deleted o User Quota o Virus protection software o Tape backup
Storage Overview
The storage space on your HP NAS VA is made up of physical and logical storage. Physical storage refers to the hardware you use for data storage. The physical storage components on the HP NAS VA include:
o Disk drives o RAID levels o Active spare
Logical storage is created by software that lets you combine disk space from multiple physical disks into a logical volume. A logical volume is a disk partition that can be comprised of physical storage on multiple devices. The logical storage components on the HP NAS VA include:
o Logical unit numbers (LUNs) o Volume groups o Logical volumes o Snapshots
Physical Storage
Disk Drives
You can configure the HP NAS VA to contain as many as 105 18GB, 36GB, or 73GB physical
14
hard disks, depending on your storage needs. Drive capacities may be mixed. If drive speeds are mixed, system performance will approximate the lowest speed drive in use.
Virtual Array
Your HP Virtual Array is preconfigured for you at installation by the HP Customer Engineer. Administrators with a strong working knowledge in HP-UX administration and the Logical Volume Manager can make changes through the Command View SDM. The term “Virtual Array” refers to the way the disks within the array are treated as a pool of data storage blocks instead of real physical disks. Further information on your VA is available in the Virtual Array section of this manual.
Active Spare
The active spare feature in the storage array offers increased protection against disk failure. An active spare ensures that the array can restore data redundancy and performance as quickly as possible following a hard disk failure.
Active spare reserves capacity to perform a rebuild in the event of a disk failure. If you are using disks of different capacities in your array, active spare reserves enough space to rebuild the largest disk. As with logical volumes, the capacity reserved for the active spare is distributed across all the disks in the array; no one physical disk contains the active spare.
Active spare is similar to the dedicated hot spare disks used in some conventional arrays. However, those arrays let the hot spare remain idle until it is needed. This array uses the active spare for RAID 1+0 storage until the spare is needed. This provides the added benefit of enhancing performance while also protecting against disk failure.
Logical Storage
Logical Unit Number
Logical unit numbers (LUNs) prepare the physical disk space for use. A logical unit number (LUN) is a unique identifier to differentiate between separate devices (each
of which is a logical unit). Each LUN is a unique number that identifies a specific unit of storage. The number of LUNs supported on your NAS VA is dependent on the array hardware installed in your solution. The VA 7400 array can support up to 1024 LUNs. The VA 7100 array can support up to 128 LUNs. Typically, your NAS VA solution will use only a very small number of LUNs.
Volume Groups
Volume groups combine the space from LUNs and make the space accessible to the file system for creating logical volumes and directories, which can then be made accessible to users.
A volume group is a collection of between 1 and 32 LUNs. A LUN may belong to only one volume group per system. Each system can contain as many as 255 volume groups. When a LUN is assigned to a volume group, the volume's physical blocks of storage media are organized into physical partitions of a size you specify when you create the volume group.
Logical Volumes
A logical volume is a section of disk space that holds computer data. A large volume group can be divided into several logical volumes or partitions, each of which is treated as a separate disk. Logical volumes are the basic unit of logical storage for a file system on the HP NAS VA. Logical volumes can be further subdivided into individual directories.
15
Snapshots
A snapshot is a read-only picture of a logical volume at a specific point in time that provides almost instantaneous access to the previous version of a file.
Planning Your Storage
You need to construct an overall storage architecture showing the amount of total storage available and how it should be allocated to different groups or functions.
Storage space is spread across volume groups. In these volume groups, you must create logical volumes to divide your disk space. You can divide each volume group into as many as 256 logical volumes. Planning storage space allocation prior to creating logical volumes is important. Although the HP NAS VA allows you to expa nd your logical volumes later, you may want to reserve extra space during setup to allow for easier expansion.
Planning LUNs and Volume Groups
LUNs can be any size up to 256 GB. Create enough LUNs so you can use all the available storage in a volume group. Volume groups can be no larger than 2 TB. That is because it is the maximum file size allowed. If you have more than 2 TB of storage in any array, you will have to create multiple volume groups for that array. You can create up to 256 volume groups.
Planning Snapshots
Snapshots are an important part of your data-protection plan. A good data-protection plan should include your backup strategy, storage redundancy provided by either AutoRAID or RAID 1+0, and snapshots. Snapshots give you nearly instantaneous access to previous versions of a file stored on your HP NAS VA.
A snapshot is a read-only picture of a logical volume at a specific point in time. When you create a file, the snapshot of that file is of zero length. However, as you modify the file, the snapshot tracks changes between the original file and the modified file. If an error occurs and you want to revert to the previous version, you can use the snapshot data and the unmodified parts of the original file to quickly and easily construct the file.
Snapshots consume storage space. When you plan your storage, you must consider how dynamic your data will be. If you have created a logical volume in which the data will change rapidly, snapshots will consume a large amount of space. At the extreme limit, a file can change so much from its original incarnation that the snapshot consumes the same amount of space as the original data. Typically, data does not change so rapidly, and the usage and growth of snapshot space is relatively slow.
Snapshots are optional. You can add or resize a snapshot at a later time if there is enough free space available in the logical volume. For information about how to incorporate snapshots into your data-protection plan, see Using Snapshots.

Using the HP NAS VA
Getting Started - Part 1
This section is a summary of how to get started with your HP NAS VA Storage system. For more details please see the following sections of this manual:
o Planning Your Storage o Getting Started - Part 2
Recommendation
Use Quick Setup if you want up to 256 GB of storage con figured quickly on your VA 7100, 512 GB on your VA 7400. Quick Setup will create a single Volume Group and a single LUN on the VA 7100, one Volume Group with 2 LUNs on your VA7400. You can then create multiple Logical Volumes onto that Volume Group with Quick Setup. Quick Setup should only be used 1 time, thereafter you need to use Advanced Setup for your storage configurations.
Use Advanced Setup for creating multiple Volume Groups and Logical Volumes, or Volume Groups and Logical Volumes of differ ent sizes. Use Advanced Setup either from the start, or to manage your storage after one usage of Quick Setup. Advanced Setup can be used to expand the size of the Volume Group created with Quick Setup.
Understanding NAS VA Storage Terminology
NAS VA storage progression: LUN (device) > Volume Group > Logical Volume > mount point/share LUN (device) – A “device” or LUN is a group of storage (i.e. “blocks”) striped across ALL disks in the Array (behavior unique to HP’s Auto Raid). An array must have at least one LUN and can have as many as hundreds of LUNs. HPUX naming conventions refer to LUNs as devices; we attempt to use LUN throughout this document. Volume Group (VG) – the next level of grouping storage. VGs are made up of one or more entire LUNs. By design, it is not possible for a single LUN to be a member of more than one VG. VGs can contain LUNs from multiple arrays connected to the NAS head via multiple FC-HBAs or FC hubs or switches. This is usually done to distribute the data load across more disks to increase performance.
Logical Volume (LV) – a “slice” of the grouped storage (i.e. VG). The LV can be very small or use all of the space available in a single VG, but it cannot span VGs. CIFS shares (for Microsoft based OSs) and NFS mount points (for UNIX based OSs) provide access to the available storage in a LV.

Quick Setup (QS) - is intended to be the shortest path to configure up to 256/512 GB of storage.
QS does not offer the flexibility and breadth of space/performance/redundancy options that the Advanced Setup (utilizing LUNs creat ed via Command View SDM) does.
The “add storage...” feature of QS provides the ability to create Logical Volumes and related NFS mount point and/or CIFS share of the size of your choice on a single Volume Group created by Quick Setup.. QS does not provi de the ability to create a VG utilizing LUNs from multiple arrays.
Advanced Setup (AS) - provides the ability to create up to 256 VGs and up to 255 LVs and mount points/shares dependent upon the configuration and number of LUNs that exist on the array(s). AS relies upon having previously created LUNs via QS or, more preferably, via Command View SDM.
Command View SDM – accessible from “Command View SDM” in the navigation tree of the Storage tab from the Command View NAS. This tool offers the ability to manage your storage at the lowest level (LUNs). It provides the ability to create, delete and manage LUNs and all other Array specific management features. When performance, space or specific configurations are required, configuration via Command View SDM is required.
Command Line
SAM – VGs, LVs and mountpoints may be created, but NFS exports and CIFS shares can’t be
created in SAM. SAM is subject to a similar limitation as the GUI – LUNs cannot be created via SAM. SAM is the most intuitive of the command line functions available to you, but can not provide all the functionality needed.
Command View – a text-based version of Command View SDM. Running CVUI (located in /opt/sanmgr/commandview/client/sbin) provides a text-based, menu driven interface from the command line with all of the storage management capabilities of Command View SDM.
LVM commands – pvcreate, vgcreate and others are LVM (Logical Volume Manager) commands. LVM sits on top of UX and performs just what it’s title says – manages (everything
19
up to) Logical Volumes. Please refer to your UX documentation for instructions regarding all of the various LVM commands, parameters and their correct usage.
Items to be aware of:
Volume Group Creation
o QS is the fastest way to create usable storage for NAS VA. It provides one Volume
Group of up to 256 GB and a single LUN of up to 256 GB for you on VA71000, and one Volume Group of up to 512 GB with up to 2 LUNs of 256GB each on the VA7400 array.
o QS creates storage based upon the World Wide Name (wwn) of each VA series storage
array. Using QS creates a single VG, named VG(wwn), per attached VA. QS recognizes ONLY VGs created with the VG(wwn) convention, thus only one VG per array is recognized by QS. Any VGs created via AS or SAM using the default VG name (e.g. vg01) will NOT be recognized by QS.
LUN Creation
o Command View NAS (GUI or console) and Command View SDM provide the ability to
add, delete or modify LUNs (devices). The Command View NAS GUI creates LUNs only when QS is used. Once storage has been configured via QS or AS, LUNs deleted or modified utilizing either Command View NAS or Command View SDM will destroy all data within the associated VGs/LVs.
Adding Storage to an Existing Volume Group, Expanding the Size of an Existing Volume Group
o The Volume group size is defined during QS storage configuration or AS setup. If a VG
is desired to be extended beyond the original size, the data must be moved or copied elsewhere PRIOR to the VG being reconfigured. Failure to do this could result in loss of data!
Getting Started - Part 2
To begin using your HP NAS VA, you need to:
o Install your NAS VA through the installation documentation provided.
o The first time the system boots, it will run set_parms initial. This allows you
to set a number of system parameters necessary to be able to manage your system from the NA S web interface. See the section below on the set_parms command for further information.

Networking Settings
TCP/IP Settings
IP Addresses
The HP NAS server has multiple PCI slots available for Network Interface Cards (NIC). The number of PCI slots available is dependent on the server you purchased for your system. NICs can be single-port, dual-port, or quad-port 10/100 cards, or single-port gigabit cards. A list of currently supported hardware (including NICs) is available on the support web site. When you initially set up your HP NAS VA, you need to configure the primary NIC. You have two choices:
?? If you have DHCP enabled, NIC configuration occurs automatically. Depending on your
configuration, the DHCP server provides any or all of the following parameters: IP Address, Subnet Mask, Gateway Address, Broadcast Address, DNS Domain Name.
?? Connect a laptop to the server management port using a null-modem serial cable, and
use terminal emulation software to log in. Access the text interface to manually configure the primary NIC (unless you have Dynamic Host Configuration Protocol [DHCP]). You can use the NAS web interface to configure additional NICs. However, you must fi rst configure the network settings through the serial port or you will not be able to access the HP NAS VA through the web-based user interface. See the Getting Started - Part 2 section of this manual for more information.
The following list shows what BOOTP/DHCP vendor options are supported:
o BOOTP_OPTION_NETMASK o BOOTP_OPTION_GATEWAY o BOOTP_OPTION_DNS o BOOTP_OPTION_DOMAIN o BOOTP_OPTION_BROADCAST o BOOTP_OPTION_HOSTNAME o DHCP_OPTION_WINS o DHCP_OPTION_LOGSRVS o DHCP_OPTION_LPRSRVS o DHCP_OPTION_NTPSRVS o DHCP_OPTION_XFNTSRVS o DHCP_OPTION_XDMSRVS
To enter the IP addresses for secondary NIC ports:
1. Using the NAS VA web interface, click the Configuration tab.
2. Navigate down the System Configuration tree to Networking Settings > TCP/IP and select IP Addresses. Your current NIC configuration is displayed.
3. For each available NIC card, choose either Use DHCP or Manually Configure. If you select Manually Configure , enter the:

NFS Settings
NFS Settings
Network File System (NFS) settings are optional. NFS is a client/server application that lets a computer user view and optionally store and update files on a remote computer as though they were on the user's own computer.
1. Using the NAS web interface, click the Configuration tab.
2. Navigate down the System Configuration tree to the Networking Settings and select NFS.
3. A table displays a list of exported file systems and their associated access lists.
4. Select a file system from the list.
5. Click the Action button for available choices in managing your NFS settings.
o Refresh - updates your screen o Add NFS Export
o Edit NFS Export o Remove NFS Export o Examples - displays a list of example NFS Access Lists
Note that as you make changes to your NFS settings, the status column will list the change as pending. You may have multiple simultaneous pending changes. Changes do not take effect until you click apply.
If desired, you may change the number of Network File System Daemon (NFSD) processes. This value specifies the number of NFSD proc esses that are created on the NAS device. This value takes affect immediately; NFS is restarted with the new number of daemons. This setting has a direct affect on NFS performance.
o A single NFSD process (for example, a value of 1) can support many NFS clients, but
it must provide service in a sequential fashion. This would create performance issues if more than one NFS client was trying to access the NAS device.
o A large number of NFSD processes could support the same number of NFS clients,
but do so in parallel, thus increasing the performance for the clients. The more NFSD processes you have, the more system resources are used. Specifying a large value
could also result in poor performance. You can use a minimum value of 1 and a maximum value of 128. If you are you using your NAS device primarily as an NFS server, HP recommends that you increase the value of
this setting.
5. Click Apply.
You do not need to restart the system.
35
CIFS Settings
CIFS Settings (Samba)
Common Internet File System (CIFS) settings are managed within the Samba web interface.

Your HP NAS VA must be completely configured before you attempt to set up your storage using the Storage tab. For more information on configuring your system, refer to the Getting Started ­Part 1 and Getting Started - Part 2 sections of this manual, the HP NAS VA Configuration Guide, and Help for the Configuration tab The Storage tab is provided to allow you to manage the storage on the HP NAS VA. It is divided into two main sections:
o Quick Setup - selections include RAID Device Setup and Physical Device Quick Setup
This selection is provided to allow quick initial setup of your storage devices. Arrays are managed in the RAID Device Setup selection. Hard Drives are managed within the Physical Drive Setup selection.
o Advanced Setup - the Local Storage section allows you to select Physical Devices,
Logical Vols/Volume Groups, and Mounted File Systems. These pages allow you to manage attached disk and RAID storage devices at the Logical Vol ume manger level. The Command View SDM section allows management of externally attached RAID arrays. .
Caution: Use of the Advanced Setup Tools functions require you to use Command View SDM to create and manage LUNs. Incorrect use of the Advanced Setup tools can result in data loss.
37
Quick Setup
RAID Device Setup
For RAID device setup with a new system, please review the instructions in the Getting Started ­Part 1 and Getting Started - Part2 sections of this manual. In the NAS web interface Storage tab > Quick Setup, select RAID Device Setup.
The RAID Device Setup page manages any VA 7100 and/or VA 7400 attached storage. You can initialize these devices and create Logical Volumes which can be shared with external systems via NFS or CIFS.
Note: RAID Device Setup is used only for initial setup of your system. Your HP NAS VA solution
will determine the storage capacity and configuration that can be setup through RAID Device Setup per the following table
Initial Setup and Configuration
The following table tells you the limits of storage capacity and configuration for initial setup using RAID Device Setup. Once you have completed the initial setup using this tool, you can setup and configure any remaining storage via the Advanced Setup tools.
Array Model Volume Groups Max Usable
Storage
VA7100 1 256 GB 256 GB 1 VA7400 1 512 GB 256 GB 2
The current storage configuration is listed in a table at the top of the page. Any managed devices and allocated Volumes are displayed, along with their status and size. Existing Volumes may be deleted using the table Delete button, and new Volumes may be added using the Add storage on selected Device Action menu pick.
The NAS GUI treats the array(s) as one large physical disk, represented by the LUN created on the device at initialization. This disk is then added to a Logical Volume Manager (LVM) Volume Group (VG), named based on the unique ID of the storage device. Storage created by the user is allocated from this VG, mounted on the server file system, and exported to exter nal systems via NFS or SMB.
In depth status and configuration data for the RAID storage device may be obtained from the Command View SDM Web interface.
Caution: Use of the Advanced Setup Tools functions require you to use Command View SDM to create and manage LUNs. Incorrect use of the Advanced Setup tools can result in data loss.
Max LUN Size Max Number of
LUNs
Action Menu Picks
A number of storage management functions can be performed from the menu that appears when the Action button is selected.
Force Hardware Rescan (slow)
o In rare cases the GUI may not recognize externally connected storage devices. If so, a
rescan will do an exhaustive search of the attached hardware and recreate device files and a default configuration, if necessary. This may take several minutes, and is usually only needed if adding a new device or if an existing device has been moved or replaced.
38

o Prepares the storage device for use with the GUI. Any existing Logical Unit (LUN)
configuration on the device is deleted, and a new LUN is created encompassing the entire available storage. This new LUN is then added to a LVM Volume Group on the server.
o The underlying configuration of the storage device is not modified. To manage the
configuration at the lowest level (e.g. RAID levels, hot spares, etc) select the External Storage Devices tree item, which will bring up the device’s Command View SDM Web management interface.
Add storage on selected Device
o You may create arbitrary sized Volumes on the storage device which can then be
exported to external systems via NFS or CIFS. This menu item will ask for the size of Volume you wish to create, and the local CIFS Share name. It will be NFS exported by default. You may remove existing volumes listed in the Device Sum mary by using the “Delete” button displayed on the page Device Summary form.
Physical Drive Quick Setup
The Physical Drive Quick Setup page allows you the quickly configure an attached disk drive (not a RAID storage device) for use. Use this when you want to quickly configure a new physical disk drive attached to the server.
From the NAS web interface, go to the Storage tab. Under Quick Setup, select Physical Drive Quick Setup. The page will list any attached disk drives which are not being used by the system. If there are no devices available, a dialog box will report the fact.
To manage a device, first select it in the grid. You may then specify:
o a Mount Point in the local file system (e.g. /local/newdisk ) o whether the device should be NFS exported to external UNIX or Linux systems o a Share Name to be used by CIFS o whether the devices should be shared to external Windows systems via CIFS
The GUI will create a new file system on the device, mount it on the server file system and optionally export it via NFS and SMB. All existing data on the device will be lost.
Caution: Creating a new file system on the device will cause all existing data on that device to be lost!
Once created, more detailed configuration may be performed using the Advanced Setup tree items within the Storage tab. Choose one of the following Help links to learn more:

Allowing Access to Data
Granting Users Access to Data
Before network users can access the HP NAS VA, you must give them permission. This is a security concern. Each platform grants permission differently:
o Windows: Shares are permissions that let you control Microsoft Windows users' access
to data. You can create SMB shares for any directory within a file volume, including the root. Once a share is created, users may attach to the share via the Network Neighborhood in Windows and store and retrieve files and directories. If you are operating under share-level security, you can limit access to shares by creating read-only or read/write passwords. See HP NAS VA Security in an NT-only Environment for more information.
o UNIX: You create an NFS export so that users can mount that volume/directory on their
systems. However, you must first specify the access mode. If you specify a read -only or read/write access mode, users can use the mount command to access the volume from
a UNIX workstation. This restriction is only for general access to the system. User-level restrictions also apply to all of the files and directories on the volume. See HP NAS VA Security in a UNIX-only Environment for more information.
Creating and Editing Shares and Exports

Security
About HP NAS VA Security
Two basic ways to ensure the security of the HP NAS VA are:
o control access to the device o set an administrative password to ensure that only authorized users gain access to
key administrative functions Access and rights to the data that clients store on the HP NAS VA device can involve security in the Windows and UNIX environments. The subject of security is beyond the scope of this manual, but many excellent books are available. This section offers a very abbreviated discussion of key security elements that you might consider when administering your HP NAS VA, including administrative password, shares, and exports. Further informaion on security for UNIX-only environments and security for NT-only environments is available.
HP NAS VA Security in a UNIX-only Environment
UNIX File Security
UNIX uses a reasonably simple approach to data access security. Each workstation performs user authentication locally. Each user is associated with a 16-bit integer (user ID or UID). Additionally, each user can be a part of a group that is denoted by another 16 -bit integer (group ID or GID). A user can be a member of several groups, each with its own unique GID. All objects contain associated meta-data that includes the UID and GID as well as read/write/execute permissions for the object. A typical UNIX file permission might look like:
-rwxr-xr-x 1 201 5 611 Nov 11 11:09 testfile
-rwxr-xr-x 1 Wilson Engineering 611 Nov 11 11:09 testfile
In the first line, numbers represent the UID and GID; in the second line, the names associated with the UID and GID are displayed. In either case, Wilson (UID 201), who is a member of the Engineering group (GID 5), created a file that has permissions for three different groups. The permissions are represented by a string of nine characters: three characters for the permissions of each of the three groups of users. The three groups are the owner (Wilson), the group (Engineering), and other. In the example above, the owner has specified rwx (read/write/execute) privileges for himself, r-x (read/execute) privileges for the group, and r-x (read/execute)
privileges for other. In your network, you might use a Network Information Service (NIS) server to help you maintain common configuration files such as the password, group, and host files. If your environment uses
a NIS server, you can enable NIS. The HP NAS VA then maintains the same UID and GID numbers that your UNIX users are currently assigned in a heterogeneous environment.
Note: Whether you disable or enable the use of a NIS server, you are in no way affecting the
security of a homogenous UNIX environment.
An additional form of security called host access is available in the UNIX environment and controls which client machines are allowed access to the HP NAS VA, regardless of the user. The allowed clients are specified by a list of IP addresses or hostnames representing those machines. Host access controls access by machine, not user.
62
HP NAS VA Security in an NT-only Environment
The security schema for NT systems is different from that of UNIX, but there are two similarities:
o You can set up the security model to allow user authentication at the share level;
alternatively, you use a security domain, in which authentication is handled by a
Primary Domain Controller (PDC) or Backup Domain Controller (BDC).
o Processes are run with an identity of a user and any groups to which that user
belongs for either that workstation or the domain. Each data object is associated with
meta-data, sometimes called a security descriptor (SD). The security descriptor
contains a list of permissions or denials in the Access Control List (ACL), which
contains an almost limitless number of permutations that can be associated with a
data object. The HP NAS VA lets you choose between two security models:
o Share-level security o User-level (Domain) security
Additionally, host access is available in the NT environment to control which client machines are allowed access to the HP NAS VA, regardless of the user. The allowed clients are specified by a list of IP addresses or hostnames representing those machines. Host access controls access by machine, not user.
Share-Level Security
With share-level security, the server explicitly asks for permission (password) every time a user connects to a share on the HP NAS VA. Thus, any user on the network who knows the name of the HP NAS VA, the name of the resource (or file), and the password has access to the resource. When you are using share-level security, you can assign shares a read-only password and/or a read-write password.
User Level (Domain) Securit y
With user-level security, the client accessing the HP NAS VA passes the credentials of the logged-on user to the HP NAS VA system transparently. The HP NAS VA in turn queries the Primary Domain Controller (PDC) or Backup Domain Controller (BDC) to authenticate the user. Once the user is authenticated, the PDC or BDC returns a Security ID (SID) that the HP NAS VA uses to check the client's access rights. This token is then used with all subsequent requests from that client.
The HP NAS VA supports the NT Master Domain model. This allows the HP NAS VA to participate in a resource domain that is separate from the domain in which users are authenticated.
63
At boot -up time, the HP NAS VA locates the PDC in the specified account domain, as well as the domain cont roller in the specified resource domain, then logs on to that domain.
Permissions
You can assign the following permissions to an NT resource:
o Read o Delete o Write o Execute o Change Permissions o Take Ownership
Additionally, you can group these permissions into standard permissions that consist of one or more previous permissions. These standard permissions include:
o No Access o Read o Change o Full Control o Special Access (where individual permissions can be selected, such as Read +
Change Permissions)
Sharing Files Across Multiple Platforms
The HP NAS VA was designed to work well in a heterogeneous environment and support remote file access protocols for UNIX and NT clients. A major difficulty in sharing data across these environments is that the file system security models are very different. For example, NT systems that use user -level security use ACLs to identify both themselves and the permissions for each data object, whereas UNIX systems use traditional UNIX permissions that define explicit permissions for the user, group, and other. However, given some care in setting up the security environment, a reasonable level of access can be provided for cross-environment requests ( i.e., a UNIX client requesting a file created by an NT client) without overly compromising the security set by the creator of the object.
Accessing Files Created by UNIX Clients
When an NT user accesses a UNIX file, the UNIX file permissions are translated into an ACL that
64
then determines the permissions to grant. Recall from HP NAS VA Security in a UNIX-only Environment that permissions are granted to three distinct groups:
o user o group o other
If the owner of the UNIX file does not map to a user in the NT domain, then an NT user ID will be generated in the local UNIX domain. If the owner of the UNIX file is recognized (or mapped) as a known NT user, then the appropriate information will be exchanged so that the owner has the same security privileges in NT that he or she had in UNIX. A similar process occurs for the group identification and permissions. The Other field is mapped to the NT Everyone account.
65
This table shows the mapping that takes place between the permissions.
UNIX NT Equivalent
r-- Read
-w- Write, Delete
--x Execute
-wx Write, Delete, Execute r-x Read, Execute rw- Read, Write, Delete rwx Full Access
--- No Access
Note: If share -level security is being used in the Windows environment, then only the share
passwords affect access. The UNIX permissions have no effect.
Accessing Files Created by NT Clients
Directly mapping NT permissions to UNIX permissions causes some difficulty because NT permissions have a greater level of complexity. UNIX users are unable to use either the chmod or
chown commands to modify the permissions or owners of NT files. The table below shows which UNIX-to-NT file permissions are mapped.
NT UNIX
R r W w X x D Ignored P Denied O Denied
In addition to the permission mappings covered in the previous sections, the following also applies:
o If no ACLs are specified, then the UNIX permission will be rwxrwxrwx. o If the ACL is empty, then the UNIX permissions will be ---------. o If the only access allowed by the ACL grants full control to everyone, then the UNIX
permissions will be rwxrwxrwx.
o In the absence of a group ACL, the owning group will be the user's primary group
and the group permissions are set to the same value as the other permissions. Additionally, if an NT file grants permission to the everyone group (and does not specifically deny
access to the owner or the group), then the same access is given to the owner and the primary group. However, UNIX permissions look for explicit permissions for the owner, group, and other. To allow the same level of access in UNIX as NT, these files will have a permission of r--r--r--.
CIFS file locking
To ensure integrity and security of user data files despite the variable client access methods, file locking can be enabled at the file system and/or application level.

Virus Prevention and Detection
The primary purpose of NAS is file serving. It is very likely files will be accessed by multiple protocols (CIFS, NFS, HTTP, etc.) of which there will be many users. It is extremely important that procedures and systems be in place to prevent a potential disaster (corruption, data loss, system loss, etc.) via infection and that appropriat e recovery schemes are planned in the event of infection.
Your HP NAS VA utilizes the HP -UX operating system. Because of this, it is often assumed that there is no need to safeguard against viruses. However, it is very likely that these NAS servers will be used to host files from applications that have been inundated with viruses and worms. Today, more than 90% of computer viruses are executable viruses that are usually spread via electronic mail, and macro viruses that are embedded in files. Of those, Microsoft applications (Word, Excel, PowerPoint, and Outlook) are by far the most frequent carriers of viruses. Files generated and used by these applications are commonly used on NAS systems and should be safeguarded appropriately in any NAS system. The HP-UX OS has been tested and verified with Sophos Anti-Virus for Unix. Sophos Anti-Virus offers HP NAS VA customers on-demand and scheduled scanning of the NAS file systems and it also offers on -access scanning of clients on the network. Using anti-virus software is an excellent means of preventing against virus infection, however, as mentioned earlier, “procedures and systems” should be in place. Thus it is also prudent that users and administrators be aware of practices and procedures that will guard against virus infection.
The anti-virus support for your NAS VA solution provides virus checking, automatic reporting, and
67
disinfection for PCs and entire networks. Sophos Anti -Virus for Unix has two components:
o SWEEP which provides on-demand checking of files on Unix file servers or
workstations. Scheduled scans are also possible using SWEEP and standard Unix
facilities.
o InterCheck which is placed on non-Unix workstations to allow on -access virus
checking. Features of Sophos Anti-Virus for Unix:
o The engine is upgraded twelve times a year, and virus definitions are released daily
which can be downloaded from the Sophos website (www.sophos.com) or requested
to be sent by fax or email.
o Easily detects polymorphic viruses using Sophos's advanced Virus Description
Language (VDL) and a built in code emulator.
o Detects and disinfects Microsoft Office macro viruses. o Scans inside encoded and archive files. Infected files can be removed and/or
disinfected.
o Features an `immediate mode' which allows checking on deman d. o Ensures total security by providing automatic centralised reporting of every virus
incident.
o Offers on-screen help as part of the Sophos CD on which the software is delivered. o Sophos provides unlimited 24x7 live body tech support for their customers via toll -
free number and/or email at no charge (contact information will be provided at time of
purchase).

Backup
Backup Overview
Backup of NAS devices has traditionally been difficult and time consuming. Technologies such as NDMP have been developed to improve this. However, NDMP is still slower and less reliable than integrating with the native agents that most backup vendors provide. The NAS operating system used in the NAS VA is based on HP -UX. This allows backup servers and agents to be run natively on the NAS head. This provides the best performance and compatibility available today. The NAS VA supports backup via three methods:
1. SCSI/Fibre Channel connection to a tape device. The NAS head provides both an external SCSI connection and connection via the fibre channel hub or switch to a SCSI or fibre channel based tape drive or library. Backup can be performed either through local tools such as tar, or by integrating a Backup application on the NAS head. This backup option offers maximum performance, however it often requires dedicated tape resources and additional management overhead. HP OmniBack II and other leading backup software products are supported. If a non HP backup application is used, the customer is required to support the application unless a service agreement with Hewlett-Packard is written to cover the solution.
2. Network backup of the NFS/CIFS share(s). This is one of the most common ways to backup some NAS devices due to the limitations of NDMP. This is accomplished by mounting the NFS or CIFS share and backing up the mountpoint. This protects the data on the NAS device, however the configuration on the NAS device is usually not protected. Additionally, if the share is both NFS and CIFS, file attributes can be lost. This is not a preferred backup method for HP NAS VA. You should use either method 1 or method 3.
3. Backup through a backup application agent. This option utilizes the agents provided by backup vendors to protect the system. Unlike the first options, this allows the NAS device to be integrated into the existing backup scheme as any other server. It also typically provides the highest reliability and performance. Backup can either be accomplished by backing up across the IP network, the fibre channel network or to a locally attached tape device. The management console of the local backup solution handles management of the backup. Typical applications that support this backup methodology are HP OmniBack II and other leading backup software products.
69
High Availability
Clustering Overview
For mission critical environments, NAS head clustering is a requirement. The NAS VA is an ideal fit for this environment due to its modular nature. The high performance NAS head used in the NAS VA can be clustered to provide an extremely dense highly available NAS solution. In addition to high availability, clustering technologies provide scalable performance. Unlike other ways to increase performance, clustering provides an almost linear performance curve as more nodes are added to the cluster.
A high availability system allows file services to continue in spite of a hardware or software failure. Highly availiable systems protect users from software failures as well as ffrom failure of a NAS head, disk, or local area network (LAN) component via redundancy.
An MC/ServiceGuard cluster is a networked group of HP approved NAS heads having sufficient redundancy of software and hardware that a single point of failure will not significantly disrupt service. Application services (individual HP-UX processes) are grouped together in packages. In the event of a single service, node, network, or other resource failure, MC/ServiceGuard can automatically transfer control of the package to another node within the NAS cluster, allowing service to remain available with minimal interruption.
The NAS web interface provides basic functionality for both single headed and clustered NAS VA solutions. MC/ServiceGuard provides the clustering and failover specific functionality. Command line functions will also apply. For more information on managing clustered NAS heads please refer to your MC/ServiceGuard User's Manual.

Other Features
Using Snapshots
A snapshot file system is used to duplicate the contents of a file system at a particular point in time, much like taking a photographic snapshot. Although files may change in the future, you have captured the contents of the file at the moment the snapshot was created. This snapshot copy of your data is read only.
A snapshot file system consists of:
o a super block - logistical information about the snapshot o a bitmap - indicates if block in original file system has changed o a blockmap - provides address of data block in snapshot that has a copy of the
original file system block
o data blocks - copies of original contents of changed file system blocks Snapshots are managed from the command line, not from the NAS GUI. You have the tools to create snapshots within OnlineJFS, which is included in HP -UX 11i.
To create a snapshot, use:
mount [-F vxfs] -o snapof=source[,snapsize=size] destination snap_mount_point
Next, create a mount point for the snapshot:
# mkdir /snapmount
Then, mount the snapshot:
With VxVM (Veritas Volume Manager) included in OnlineJFS:
# mount -F vxfs -o snapof=/dev/dsk/datadg/uservol /dev/vx/dsk/datadg/snapvol /snapmount
Without VxVM:
# mount -F vxfs -o snapof=/dev/dsk/c0t6d0s2 /dev/dsk/c0t5d0s2 /snapmount

forest, trusted Windows 2000 forests, trusted NT4.0 domains, and grant permissions to any resource in the local domain (NT4.0 local groups grant permissions only on the computer where they exist).
o Universal Groups: Contain members from anywhere in the Windows 2000 forest or
tursted forests and can be granted permissions in any domain in the forest, or trusted forests (NT4.0 global groups contain membe rs from the local domain only).
o Group Nesting:
o Universal Groups can contain other Universal Groups and Global Groups from
any domain.
o Global Groups can contain other Global Groups from the same domain. o Domain Local Groups can contain Universal Groups, Glob al Groups from any
domain, and Domain Local Groups from the local domain.
Native Mode also allows group conversions from one group type to another:
o Between Security and Distribution Groups o Between Universal Groups and Global Groups o Between Universal Groups and Domain Local Groups
Other Features
Please see the NAS Windows 2000 documentation on the HP Support website (www.hp.com/support/nasva) for detailed information on other features available through CIFS/9000 Server. These include:
73
o Intellimirror: provid es the primary benefits related to custom mobile profiles
o User Data Management - Users have access to their data regardless of the
hardware that they logged on to.
o Software Installation and Maintenance - Users have "just in time" application
installations regardless of the hardware that they are logged on to.
o User Settings Management - Users' desktops are available regardless of the
hardware that they are logged on to.
o SIDHistory: A migration tool that is interdependent with other domain migration and
restructuring tools. It is only available in Native Mode. It addresses the issue of incongruous user accounts and access control entries on access control lists.
o PDC Emulator: Windows 2000 Advanced Directory domains include the designation
of a PDC Emulator or FSMO PDC Emulator. The PDCE is usually resident on the forest root domain controller in both Mixed Mode and Native Mode domains, but includes NT4.0 functionality when the domain is in Mixed Mode.
o Further information on Mixed vs. Native Modes, including Dial -In options.
Resizing of File Systems and Volumes
File systems and Volumes can be resized on-line from a console using the fsadm or vxresize commands without interruption of user access.
The fsadm Command
Syntax for the fsadm command is as follows:
/usr/sbin/fsadm [-b newsize] [-r rawdev] mount_point
To expand or reduce a file system to 2048000 sectors:
# /usr/sbin/fsadm -b 2048000 -r /dev/vx/rdsk/traindg/vola /vola
The vxresize Command
Syntax for the vxresize command is as follows:
/usr/sbin/vxresize [-bsx] [-F vxfs] [-g diskgroup] [-t tasktag] volume new_length [medianame]
To expa nd or reduce a file system to 4 GB:
# /usr/sbin/vxresize -F vxfs -g datadg mail 4g
Managing User Quotas
User Quotas are used to allocate a specific amount of disk space to a user
o BSD style per-user quotas are supported. o Hard limits cannot be exceeded. o Soft limits can be exceeded temporarily. o Quotas can be turned on at mount time or any later time. o The root directory must contain the file quotas.
To turn user quotas on after mounting:
vxquotaon mount_point
To turn user quotas on while mounting:
mount -f vxfs -o quota special mount_point
74
To turn user quotas off:
vxquotaoff mount_point
SNMP
SNMP Daemon
The SNMP daemon is the Master SNMP Agent and the collection of subagents that would attach to the Master Agent collectively form a single SNMP Agent. The SNMP Agent accepts SNMP Get, GetNext and Set requests from an SNMP Manager which cause it to read or write the Management Information Base (MIB). The MIB objects are instrumented by the sub Agents.
The Master Agent can bind to three kinds of subagents, namely:
o Loosely coupled subagents or separate process subagents which open IPC
communication channels to communicate with the Master Agent
o Shared library subagents which are dynamically linkable libraries o Remotely coupled subagents which could run on a different processor or operating
system and communicate with the Master Agent using TCP
To configure the agent’s contact, add the contact after the word contact: in the configuration file /etc/SnmpAgent.d/snmpd.conf or use the –C option.
Snmpdm and only one snmpdm can execute on a particular UDP port.
Traps
The agent also sends information to a manager without an explicit request from the manager. Such an operation is called a trap. By default, SNMP traps are not sent to any destination. To configure the agent to send traps to one or more specific destinations, add the trap destinations to /etc/SnmpAgent.d/snmpd.conf.
Then Master Agent <snmpdm> and the MIB -2 subagent <mib2agt> collaborate to send the SNMP traps.
Turning SNMP Functionality On or Off
To turn SNMP functionality on or off, perform the following steps:
1. From a telnet prompt, change your directory to /opt/source.
2. Run the appropriate script: snmp.start or snmp.stop

Virtual Array
Virtual Array
Your HP Virtual Array is preconfigured for you at installation by the HP Customer Engineer. Administrators with a strong working knowledge in HP-UX administration and the Logical Volume Manager can make changes through the Command View SDM. The term “Virtual Array” refers to the way the disks within the array are treated as a pool of data storage blocks instead of real physical disks. HP AutoRAID technology uses powerful mapping techniques to present the host with a logical view of the available storage in the array (see the figure below).
HP AutoRAID uses a combination of RAID 1+0 and RAID 5DP to manage data storage for you while optimizing your data access time. This is explained further, below.
Because data is spread across all of the disks in the array, logical -to-physical data maps, stored in array controller cache memory, keep track of where the data is physically located on the disks in the array. The host has no visibility of the cache data maps; it is simply presented with logical units (LUNs) for data storage operations.
Figure 1: Host visibility of storage pool
RAID Levels
Redundant Array of Inexpensive Disks (RAID) technology uses different industry -standard techniques for storing data and maintaining data redundancy. These techniques, called “RAID levels”, define the method used for distributing data on the disks in a logical unit (LUN). LUNs that use different RAID levels can be created in the same array. The array covered in this guide supports the following RAID levels: RAID 1+0 and RAID 5 Double Parity (RAID 5DP).
RAID 1+0
76
RAID 1+0 provides data redundancy and good performance. However, the performance is achieved by using a less efficient technique of storing redundant data called “mirroring.” Mirroring maintains two sets of the data: a primary set and a backup set, or “mirror”, of the primary set. Therefore, half of the disk space is consumed by redundant data. The data is also striped across the disks in the array.
Figure 2 is an example showing the distribution of primary data and mirror data in a RAID 1+0 configuration. The example shows one LUN with 10 stripes, each stripe with two data segments: n (primary segment) and n’ (“n prime” or “mirror” segment). The following data protection scheme is demonstrated for RAID 1+0:
o If two non-adjacent disks fail, there is no data loss. Either a primary segment or
its mirror segment is still available.
o If two adjacent disks fail, the data in the entire LUN is lost. In this example, two
segments and their mirrors are lost and cannot be recovered.
Note: Disks A and E are considered as adjacent disks. The segment size is some number (x)
times 520-byte blocks.
Figure 2: RAID 1+0
RAID 5DP
RAID 5DP provides data redundancy and improves cost-efficiency by us ing a more efficient method of storing redundant data. However, there is a performance penalty for each write operation. This can impact system performance if your applications frequently update large amounts of data. RAID 5DP provides high read throughput for small block-size requests (2 KB to 8 KB) by allowing simultaneous read operations from all of the disks in the LUN.
RAID 5DP uses two independent parity algorithms to create two parity values. The second algorithm provides an additional means to reconstruct data, even if a second disk fails while another disk is being rebuilt. This “double parity” scheme is referred to as “P + Q Parity.”
During a write operation, the array controller calculates “P” and “Q” parity, then distributes (stripes) the data and parity information across the disks in the LUN. The process of calculating and writing parity information affects the write performance of the array.
If a disk fails or becomes inaccessible, the array dynamically reconstructs all user data from the data and parity information on the remaining disks. If another disk fails, with double parity, it can also be recovered even while the first disk is being recovered. When a failed disk is replaced, the array automatically rebuilds the new disk with the data that once resided on the failed disk.
Note: Until a failed disk is replaced (or a rebuild on an active spare is completed), the LUN
operates in a degraded state. The LUN must use data and parity information on the remaining disks to recreate the contents of the failed disk, thus reducing performance.
77 Also, if a third disk in the LUN fails while in a degraded state, parity can no longer be used
and all data in the LUN becomes inaccessible.
Figure 3 is an example showing the distribution of user data and parity data in a RAID 5DP configuration. The example shows one LUN with five stripes, each stripe with five segments: three data segments and two parity segments (P n and Q n ). The segments are striped across the disks in a rotating fashion. The following data protection scheme is demonstrated for RAID 5DP:
o Any one disk can fail without losing data redundancy. If one disk fails, the data
on that disk can be recalculated using either the P or Q parity segment and the data stored on the remaining good segments in the stripe.
o Any two disks can fail without losing data . If two disks fail simultaneously (B and
C, for example), or if a second disk fails before the first disk is completely rebuilt, the data from both failed disks can be rebuilt. For example, both segments of missing data in stripe 1 on disk B and disk C can be recalculated using the P 1 and Q 1 parity data and the remaining data segment on disk A. Alternatively, if the segment on a lost disk is either P or Q parity data, then the parity data can be recalculated from the remaining user data.
Note: Disks A and E are considered as adjacent disks. The segment size is some number (x)
times 520-byte blocks.
Figure 3: RAID 5DP
RAID 1+0 and RAID 5DP Combined (AutoRAID)
Your Virtual Array uses a combination of RAID 1+0 and RAID 5DP (or AutoRAID) to store data. This means that the same disk within a redundancy group can have one portion of its data capacity stored in RAID 1+0, while the other portion is stored in RAID 5DP. If one disk fails, the array first rebuilds the data in RAID 1+0 (the RAID level most exposed to data loss), then rebuilds the data in RAID 5DP. On the other hand, if two disks fail simultaneously, the array first rebuilds the data in RAID 5DP, then rebuilds the data in RAID 1+0. Thus, your array optimizes the data rebuild process, greatly reducing your exposure to data loss.
Your virtual array will survive two simultaneous disk failures within a redundancy group, without losing data, as long as none of the data segments in the disks are mirrors of each other.

HP recommends that at least one drive be assigned as a global active spare at all times. If a drive fails and no active spare is present, system warnings alert you that a drive failure occurred and that the logical drive (RAID set) is in a critical state. Although the system continues to rebuild and serve files without interruption, there is a much greater risk of data loss in this state. The drive replacement kit provides detailed instructions for installing replacement drives, rebuilding the critical RAID set, and assigning an active spare.
the system without a network connec program can then be used to interact with the system's menu-driven

of a logical volume when you create the volume. Thus, there is no need to manage mount points on a directory by directory basis. Refer to your UNIX users guide for more information about mount points.
By default HP -UX uses a negative value UID/GID, e.g., nobody = -2. CIFS/9000 should mask this by creating a user called "smbnull" which has a positive UID/GID.. If it is not there, you should use a guest user name "nobo dy" and make sure it has a positive UID/GID. Check for negative value UID/GID in user accounts in etc/passwd and change to a positive value.

Release Notes
The following late-breaking information supplements the HP NAS VA User's Guide and online help. If information in the User's Guide conflicts with information presented here, the information in this file should be considered correct.
Browser Issues
1. NFS Settings: Creating an NFS export allows access list to be assigned, but not permissions. By default, the export will be accessible to all users providing 777 permission. To restrict permissions, go to console and use the chmod command. For help on chmod, type: man chmod
2. CIFS Settings (Samba): If you are using Netscape Navigator as your web browser, you are likely to have problems using the Samba web interface. The buttons at the top of the page do not respond properly. A work around for this problem exists:
o Click on the button you wish to select. o Then right click on the same button. A menu appears. o Select reload frame.
3. Managing Logical Vols/Volume Groups: When changes are made in the Quick Setup and Advanced Setup Sections of the Storage tab, the results may not be automatically updated. To ensure that the latest information is displaying, set your browser to:
o Refresh a page every time it is visited o Bypass the proxy server for this IP address
4. CIFS Settings (Samba): Internet Explorer problem with using incorrect user name. If you use the incorrect user name, you will be locked out of Samba. You need to close the browser and reopen it.
5. NIS Settings: If you run into problems with NIS, be sure to check out the help documentation for NIS Settings. The browser does not automatically change the
nsswitch file. The help documentation provided describes how to manually edit the nsswitch file using the sam command. NIS changes made in the NAS web interface
will take effect upon the next reboot. If you are also setting up DNS, be sure to read the item below, before proceeding. Changes to the nsswitch file using the sam command can be done concurrently for NIS and DNS initial setup.
6. Domain Name Service (DNS): If you run into problems with DNS, be sure to check out the help documentation for Domain Name Service (DNS). The browser does not automatically change the nsswitch file. The help documentation provided describes how to manually edit the nsswitch file using the sam command. If you are also making NIS settings, be sure to read the item above before proceeding. Changes to the nsswitch file using the sam command can be done concurrently for NIS and DNS initial setup.
82
Known Problems
1. Dual homed systems: If you have a problem communicating with your arrays on a dual homed system, including failure of the armdiscover command, there are several items that should be investigated:
o Check to make sure the following file exists
/opt/sanmgr/hostagent/config/commIpAddr.txt
This file contains the IP address of the default or onboard NIC (LAN0). If the file does not exist, you should cre ate it.
o The netconf file can tell you the IP address of LAN0. It is found in the following
directory:
/etc/rc.donfig.d
o Settings in the following files in the /etc directory should also be checked:
hosts - Lists hostname of system with its associated IP ad dress. The first host
entry needs to be the default (LAN0) setting.
resolv.conf - The first nameserver listed needs to be on the same network as
the default (LAN0).

Glossary
Glossary
A
Access Control List (ACL)
A list associated with a file that contains information about which users or groups have permission to access or modify the file.
Active spare
A previously installed physical drive used as a backup in case an assigned drive fails. The active spare automatically takes over the duties of the failed drive.
Agent
A program that performs a background task for a user and reports to the user when the task is done or some expected event has taken place. The HP NAS VA uses backup agents to back up data remot ely.
Aggregation
The combining of multiple similar or related operations into a single one.
Authentication
The process of matching credentials provided by the user against an equivalent entry on the SAM database. A user's name and password are compared against an authorized list and if the system detects a match, access is granted to the extent specified in the permission list for that user.
AutoRAID
AutoRAID implements RAID technology automatically without requiring you to know all the complexities of det ermining and setting up different RAID modes. AutoRAID is an advanced array storage technology that provides the best combination of cost, performance, and availability.
B
Bond channel
A failover mechanism that automatically switches a specific NIC port to a standby network upon the failure or abnormal termination of the currently active system.
Broadcast address
The address that can be used to send messages to all machines on the subnet. Applying the subnet mask to the IP address provides the subnet.

See Dynamic Host Configuration Protocol.
Domain (NT)
A group of computers that share a common domain database and security policy.
Domain (TCP/IP)
An alphanumeric representation of an association of computers. (For example, hp.com. com is a top level domain and hp is a second level domain.
Domain Name Service (DNS) Server
A server that translates domain names (such as hp.com) into IP addresses (such as
15.12.255.67). If you have multiple DNS servers on your network, and one DNS server cannot translate a domain name, it asks another one, and so on, until the IP address is found.

A module containing one or several random access memory (RAM) chips on a small circuit board with pins that connect it to the computer motherboard.
Dynamic Host Configuration Protocol (DHCP)
Software that automatically assigns IP addresses to client stations logging onto a TCP/IP network. It eliminates having to manually assign IP addresses, and it allows a larger group of machines to share a limited pool of addresses, assuming not all machines are on the network at the same time. DHCP can assign a new address to each machine at startup (dynamic) or permanent (static) addresses can be assigned. Newer DHCP servers dynamically update the DNS servers after making assignments.

87
N
Network File System (NFS)
An network protocol designed by Sun Microsystems that allows all network users to access shared files stored on computers of different types. Users can manipulate shared files as if they were stored locally on the user's own hard disk.

R
Redundant Array of Independent Disks (RAID)
RAID is a metho d of combining several disk drives into a single logical storage unit. RAID offers the advantage of fault tolerance by providing real-time data recovery when a disk drive fails, increasing system uptime and network availability. RAID also increases system performance when multiple drives work together.
Remote event log
A file located on a UNIX machine containing statistics and error messages.
88
S
SCSI
See Small Computer System Interface.
Security Account Manager (SAM) database
A database used to authenticate users.

Share
To make files, directories, or folders accessible to other users over a network.
Share Level Security
Share level security for Windows NT is the simplest security method available. Access to file volumes or directories (shares) may be restricted on a share by share basis. The administrator can set read only passwords and read/write passwords for each share on the system. Users wishing to gain access to a share are asked to supply the correct password. Only users with the correct password are given access to the share.
Share Name
A name selected by the system administrator as a way of identifying a share. Share names are usually selected to be easy to remember.
Simple Network Management Protocol (SNMP)
The network management protocol for TCP/IP. In SNMP, agents, which can be hardware as well as software, monitor the activity in the various devices on the network.
Small Computer System Interface (SCSI)
A SCSI interface is used to connect microcomputers to SCSI peripheral devices, such as many hard disks and printers, and to other computers and local area networks.
SMB
See Server Message Block.
SMP
See Symmetric Multiprocessing.
Snapshot

SNMP
See Simple Network Management Protocol.
Subnet Mask
A 32-bit numeric mask that blocks out all but the necessary information. This allows the IP address to be broken into a component that identifies the subnet on which the device resides and the ID of the device itself.
Symmetric Multiprocessing (SMP)
A computer architecture in which multiple processors share the same memory, which contains one copy of the operating system, one copy of any applications that are in use, and one copy of the data. Because the operating system di vides the workload into tasks and assigns those tasks to whatever processors are free, SMP can potentially service more transactions within a fixed amount of time than a single processor system.
System log
A file containing statistical information and error messages.
System Hostname
The system name uniquely identifies your HP NAS VA. It is a text string up to 15 characters drawn from the alphabet (A -Z), digits (0-9), and minus sign (-). Note that periods are only
89
allowed when they serve to delimit component s of "domain style names." No blank or space characters are permitted as part of a name. No distinction is made between upper and lower case. However, the name must begin with a letter and the last character must not be a minus sign or period. The name you use appears on the Identity screen of the user interface and in Network Neighborhood in a Windows networking environment.
T
TCP/IP
A commonly used networking protocol that allows interconnection of different network operating systems. TCP/IP stands for Transmission Control Protocol/Internet Protocol.
Telnet
A protocol that provides console services remotely. The Telnet program runs on your computer and connects your PC to the NAS VA through the network. You can enter commands through the Telnet program and they are executed as if you were entering them directly on the server console.
Trap
A type of SNMP message used to signal that an event has occurred.
U
Uninterruptible Power Source (UPS)
A device that is connected between a computer (or other electronic equipment) and a power source that ensures that electrical flow to the computer is not interrupted because of a blackout. UPS protects the computer against potentially damaging events such as power surges and brown-outs.
User Authentication
See Authentication.
User Identification (UID)
A unique number in the UNIX environment that identifies an individual to a computer system.
User Level Security
The HP NAS VA uses a domain controller to authenticate users when they access the device. Access Control Lists (ACLs) define a user's access rights to a particular object. Users accessing the resources of the system must be logged onto an NT domain and must have specific rights to access the given resource. The resource is not only the share, but the directories and files within the share as well. Administrators and users may restrict access to any file, directory, or group of files and directories to any user or group of users in the domain.
User quota
Allows you to restrict the space usage on the HP NAS VA for users.
V
Volume group (VG)
An aggregation of one or more LUNs.
90
W
Windows Internet Naming Service (WINS)
The Windows NT Server method for associating a computer's host name with its address.
Workgroup
A group of computers on a network that connect to each other using peer relationships.
