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

be shown the current system time in that time zone for your verification. You have the
option of changing or accepting the system clock setting shown.
o Next, you enter the IP address and verify it. On-screen qualifications for the IP address
are given.
o You are asked if you want to set additional parameters: subnet mask and gateway
default address, DNS, and NIS.
o If accepted and If more than one NIC is installed, you will get a message indicating
that this command only sets the default network interface. It also tells you to use
SAM to configure additional NICs.
o The next page asks if you want to set the subnet mask and the the gateway default
address.
o If accepted, you will set the subnet mask and the gateway IP address per the on -screen
instructions. You are asked to verify your entries.
o Next, you are asked if you want to set the local domain name and the DNS server IP
address.
o If yes, you are asked to set the local domain name and the DNS server IP address. You
will be asked to verify your entries.
21
o You are then asked if you want to specify NIS.
o If yes, then you will enter the domain name
o Next you set the NIS server name or IP address
o Finally, you are asked to verify the domain name and NIS server name or IP address..
o When done, you will need to reboot your system.
o Upon rebooting, the system will be manageable from the NAS web interface where you
can setup and configure your solution's additional parameters.

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:
o IP Address
o Gateway Address
o Subnet Mask
You may have multiple simultaneous pending changes.
.
4. Click Apply.
Note: Enabling DHCP disables manually configuring addresses.
