Product Information

The NAS 1000s provides performance gains over general purpose servers by integrating
optimized hardware components and specialized software. Integrating NAS devices into the
network improves the performance of existing servers because NAS devices are optimized for
file serving tasks.

19NAS 1000s Administration Guide

System Overview

Product Manageability

The NAS 1000s ships with the following utilities and features that ease the administration
tasks associated with managing the system:

■ The Rapid Startup Utility is a user friendly configuration utility that ensures easy

configuration.

■ The WebUI is a simple, graphical user interface (GUI) that helps with administration

tasks.

Product Redundancy

The NAS 1000s is specifically designed to perform file serving tasks for networks, using
industry standard components to ensure reliability.

Other industry standard features, such as redundant array of independent drives (RAID) and
remote manageability, further enhance the overall dependability of the NAS 1000s.

To ensure redundancy and reliability, the hard drives installed in the NAS 1000s are configured
so that a single drive failure will not cause data loss or system failure. The NAS 1000s is
configured a with dual boot capibility. When powered on, the NAS 1000s can boot using a
primary OS or a secondary recovery OS. The primary OS resides on drive 0 and is mirrored
on drive 1 while the secondary OS resides on drive 2 and is mirrored on drive 3. If the primary
OS becomes corrupted and un-bootable, the secondary OS is available for data backup prior to
using the Quick Restore DVD to restore the system to the factory default state.

The data volume is configured as a RAID 5 volume across all four drives. This ensures
redundancy in the event of a drive failure and the data volume is accessible by both the primary
OS and secondary OS.

Product Scalability

The NAS 1000s offers optimized performance for a growing environment. Storage capacity
can increase as a business grows without downtime or compromised performance. Internally
the NAS 1000s can grow up to four data drives. With four 250GB disk drives storage capacity,
it can grow up to 1TB of raw storage.

20 NAS 1000s Administration Guide

Deployment Scenarios

The default shipping configuration contains two 10/100/1000 integrated network interface
controller (NIC) ports for client data access. These data ports also allow access to the Web user
interface (WebUI) that accompanies the product. It is from the WebUI that most management
and administrative procedures can be accomplished.

Typical deployment scenarios include:

■ File server consolidation

As businesses continue to expand their information technology (IT) infrastructures, they
must find ways to manage larger environments without a corresponding increase in IT
staff. Consolidating many servers into a single NAS device decreases the number of points
of administration and increases the availability and flexibility of storage space.

■ Multiprotocol environments

Some businesses require several types of computing systems to accomplish various tasks.
The multiprotocol support of the NAS 1000s allows it to support many types of client
computers concurrently.

■ Protocol and platform transitions

When a transition between platforms is being planned, the ability of the NAS 1000s to
support most file sharing protocols allows companies to continue to invest in file storage
space without concerns about obsolescence. For example, an administrator planning a
future transition from Windows to Linux can deploy the NAS 1000s with confidence that
it can support both CIFS and NFS simultaneously, assuring not only a smooth transition,
but also a firm protection of their investment.

■ Remote office deployment

Frequently, branch offices and other remote locations lack dedicated IT staff members. An
administrator located in a central location can use the WebUI of the NAS 1000s, and
Microsoft Terminal Services to configure and administer all aspects of the NAS 1000s.

System Overview

21NAS 1000s Administration Guide

System Overview

Environment Scenarios

The NAS 1000s is deployed into one of two modes:

■ Wo rkg ro up

■ Domain (Windows NT Domain or Active Directory Domain)

The NAS 1000s uses standard Windows user and group administration methods in each of
these environments. For procedural instructions on managing users and groups, see Chapter 4,
User and Group Management, of this guide.

Regardless of the deployment, the NAS 1000s integrates easily into multiprotocol
environments, supporting a wide variety of clients. The following protocols are supported:

■ Common Internet File System (CIFS)

■ Network File System (NFS)

■ NetWare Core Protocol (NCP)

■ Hypertext Transfer Protocol (HTTP)

■ File Transfer Protocol (FTP)

■ AppleTalk for Macintosh (AFP, also called MAC)

Workgroup

Domain

In a workgroup environment, users and groups are stored and managed separately, on each
member server of the workgroup. Workgroups are typical for very small deployments where
little or no computing environment planning is required.

When operating in a Windows NT or Active Directory domain environment, the NAS 1000s is
a member of the domain and the domain controller is the repository of all account information.
Client machines are also members of the domain and users log on to the domain through their
Windows based client machines. The domain controller also administers user accounts and
appropriate access levels to resources that are a part of the domain. Additional information
about planning for domain environments can be found at:

http://www.microsoft.com/windows2000/technologies/directory/ad/default .a s p

The NAS 1000s obtains user account information from the domain controller when deployed
in a domain environment. The NAS 1000s itself cannot act as a domain controller.

22 NAS 1000s Administration Guide

User Interfaces

There are several user interfaces that administrators can use to access and manage the NAS
1000s. Two of these interfaces are:

■ NAS 1000s WebUI

■ NAS 1000s Console

Each interface contains the same or similar capabilities, but presents them in a different
manner. Each of these interfaces are illustrated in the following sections.

NAS 1000s Web-Based User Interface

The WebUI provides for system administration, including user and group management, share
management, and local storage management.

To access the WebUI, launch a Web browser and enter the following in the address field:

Installing and Configuring Data Replication Software

Data replication is the process of making a copy of system data. StorageWorks NAS Data
Copy is a real time data replication and failover software product that augments existing data
protection and tape backup strategies. This product is not intended to replace regular tape
backups.

Using NAS Data Copy, mission critical data and data that must be protected is marked. NAS
Data Copy replicates this data in real time from the production machine (source) to a backup
machine (target). The target machine can be either on site or off site. After the initial copy out,
NAS Data Copy monitors any changes to the specified data files and sends only the changes to
the target machine.

NAS Data Copy can operate in many different system environments, including:

■ Single machine—Source and target components are loaded on the same machine,

allowing data to be replicated from one location to another on the same machine.

■ One-to-one—One target machine, having no production activity, is dedicated to support

one source machine. An alternative one-to-one scenario is when each machine acts both as
a source and a target, actively replicating data to each other.

■ Many-to-one—Many source machines are protected by one target machine.

■ One-to-many—One source machine sends data to multiple target machines. The target

machines may or may not communicate with each other.

■ Chained—One or more source machines send replicated data to a target machine that in

turn acts as a source machine and sends selected data to a final target machine.

NAS Data Copy is supported for all deployments of the NAS 1000s.

Persistent Storage Manager

Persistent Storage Manager lets the administrator make replicas, called snapshots, of disks in a
matter of seconds. Snapshots enable the creation of multipurpose virtual replicas of production
data without having to physically copy the data. They can be used to immediately recover a
lost file or directory, to test a new application with realistic data without affecting the "real"
data, and to serve as a source of data for backups. Snapshots record data changes on volumes
and are thus not a replacement for off-line backups.

This chapter covers the following items:

■ Operational Overview

■ Data Recovery

■ Snapshot (Persistent Image) Considerations

■ Accessing Persistent Storage Manager

Operational Overview

3

Each snapshot is a complete point-in-time representation of the data on the volumes. Each
snapshot requires only a fraction of the hard-drive capacity of the original data. PSM does not
keep all the data that was ever written. PSM maintains only the data required to maintain a
snapshot.

PSM works below the operating system as a Filter Driver at the Volume block level. PSM
maintains a library of snapshots, each representing a specific point-in-time. Snapshots can be
accessed by users, administrators, or any Windows application, and look just like the familiar
file/folder view.

With the first snapshot taken on a target volume, PSM establishes a cache file for that volume
within which PSM retains overwritten data required to build a snapshot. The cache file size is
based on a percentage of the volume it resides on and is configured through the WebUI; the
default is 10 percent. As soon as the first snapshot is taken, PSM starts monitoring all writes on
the target volume. When a write request occurs, PSM intercepts and pauses the write, reads the
data that is to be overwritten, and saves the data in a Diff Directory within the PSM-specific
cache file. After the original data is written to the Diff Directory, the new data is written on the
active volume. This process is referred to as "copy-on-write." Only the first write forces a
copy-out, subsequent writes to the same data block does not force a new copy-out, unless of
course a new snapshot is taken between the initial and subsequent write.

PSM can create and manage up to 250 snapshots system wide. A snapshot can cover several
volumes at once with an upper limit of 63 volumes within a single snapshot. However, when
reverting from a "grouped" snapshot, the revert is non-selective and it reverts all volumes
associated with the "grouped" snapshot.

39NAS 1000s Administration Guide

Persistent Storage Manager

Reading Snapshots

Users who have been granted access by the NAS Administrator see snapshots as network
shares.

A snapshot is a representation of the NAS volume at the time it was created. During the
copy-on-write operation, the data to be overwritten is preserved in the PSM Diff Directory.
When reading a snapshot, PSM determines if the data has changed, meaning it is located in the
Diff Directory, or if it is on the live volume. For data that has changed, PSM inserts the
original data, held in the Diff Directory and, where no changes have occurred, PSM reads
directly from the live volume.

Creating Snapshots

Creation of snapshots is scheduled through the SAK interface or may be generated by the NAS
Administrator as a one-time request. When the command to create a snapshot is issued, PSM
begins monitoring the file system looking for a quiescent period. A quiescent period is the
amount of time a volume must be dormant before a snapshot is created. The default quiescent
duration is five seconds but the NAS administrator may configure this, as can the amount of
time PSM should search for this inactivity window. The quiescent period provides sufficient
time for completion of writes and for the various software buffers to flush, the premise being
that, by the end of the quiescent period, a volume will be produced which is in a stable state
meaning that the volume is at rest and in a functional condition ready for users to access. If the
volume is captured in a stable state, then that volume, or files and folder contained in the
volume, will be returnable in a stable state or "useable condition" to users.

Following the quiescent period, PSM creates the snapshot.

PSM Snapshot Attributes

When creating PSM snapshots there are three basic attributes which affect the life and
consistency of the snapshot. They are Read-only, Read/write and Always Keep. Read-only
should be used to enforce the integrity of a snapshot so that changes can not be made to.
Read/Write can be used in instances where test data is useful, such as developers altering a test
website. Always Keep is useful when a snapshot needs to live indefinitely. These attributes are
described in detail below.

Read Only

The default setting is for PSM to create "READ ONLY" snapshots which prohibits any
modification to the snapshot - this is the most common parameter for snapshots. A READ
ONLY snapshot allows users, who have been granted access, to view, open and save a copy of
any file represent in the snapshot. The properties of a READ ONLY snapshot may be modified
by the NAS Administrator to READ/WRITE or ALWAYS KEEP.

Read/Write

The READ/WRITE attribute may be assigned at the time of creation or the NAS
Administrator may at any time change the attribute of any snapshot. READ/WRITE snapshots
provide some unique capabilities to PSM.

READ ONLY snapshots changed to READ/WRITE snapshots and then modified return the
data represented in the snapshot to the way it was originally, effectively acting as an UNDO.

40 NAS 1000s Administration Guide

Other applications for READ/WRITE snapshots: CFOs and auditors can run trial balances to
accounting systems without affecting the actual systems. Prototyping, a new version of a
program, can be installed in a READ/WRITE snapshot and its compatibility within the system
tested with no adverse effects to the primary system.

Always Keep

ALWAYS KEEP snapshots are treated as untouchable by PSM. In a cache file fill situation
PSM will cease writing to the cache file to avoid deleting or corrupting an ALWAYS KEEP
snapshot. A "disk full" error will be returned to the user. ALWAYS KEEP allows the
administrator to set some milestones that are not subject to the automatic deletion routines.

Automated Snapshot Deletion

PSM has a snapshot weighting system (low to highest) that helps set the priority of the
snapshot. This weighting combined with the age of the snapshot determines the order by
which it is deleted by PSM when the cache file fills up.

A key fact to consider is that PSM provides Primary Data Protection automatically. Once set
up, PSM continues to provide Data Protection generating new scheduled snapshots or deleting
older snapshots with little or no input required from system administrators.

Persistent Storage Manager

Data Recovery

File/Folder/Volume Recovery

PSM facilitates instant data recovery from the stored on-line images. Individual files, groups
of files, folders, groups of folders or complete volumes can be restored. Recovering the data
can be accomplished by the NAS Administrator or the NAS Administrator can give individual
users access to their data for that purpose through file share access over the network.

Security rights and privileges, as well as file and directory attributes, remain in effect as they
were at the time the snapshot was created.

Snapshots and Drive Defragmentation

A drive defragmenter attempts to consolidate files on a drive by reading various parts of the
files and rewriting them to become contiguous on the drive. When volumes are created they
are initially contiguous as possible on the underlying storage units (RAID arrays and LUNs).
If defrag utilities are used on volumes where snapshots exists, snapshots would grow as the
defrag utility moves blocks from one part of the disk to another. PSM disables defrag on
volumes that have current running snapshots to prevent the unnatural growth of the snapshot.

PSM (current versions) is fully compatible with the Windows 2000 system file defrag utility.
On drives upon which snapshots are not installed or are not active, the defrag utility runs
without interruption. If snapshots are active, by design, the drive is automatically marked as
unavailable for defragmentation. In operation, the utility works as designed - providing defrag
on volumes where it is allowed and omitting drives with active PSM Images. There is no user
intervention required. This is consistent with the defragmentation handling of system and
special files and is officially supported by the Microsoft defrag API. In the rare case when an
existing volume requires defrag, disable scheduled snapshots, delete all snapshots on the
volume and defrag the volume. When defrag completes, re-enable scheduled snapshots.
Defrag is only effective when there are NO snapshots active on the volume being defragged.

41NAS 1000s Administration Guide

Persistent Storage Manager

Note: Defragmentation can not be performed if snapshots exist. To defragment a disk, first delete

the snapshots. Drive defragmentation only operates on volumes formatted with a 4 KB or smaller
allocation size. HP recommends larger allocation cluster sizes to improve performance.

PSM and Backup

Because snapshots are quick to create, it is possible to capture a coherent view of the volume
data with little or no application downtime. Lack of application downtime removes the
traditional backup window or the amount of time taken to back up to offline media. While
many applications must be shut down to capture an accurate backup, snapshots capture a point
in time view of the data that can be used as the source of backup data. Applications can
continue processing against the volume. Therefore, applications may only have to be
interrupted for a few seconds during the snapshot process.

Caution: Snapshots are not a replacement for reliable, periodic data backup. If free cache

space becomes critical, snapshots are automatically deleted. See the "Automated Snapshot
Deletion" section. In addition, snapshots are a short term convenience and may reside on
the same physical drives as the data. If something happens to the data drives, the snapshots
are also affected. Read Appendix A for suggestions on how to back up the NAS device.

Although snapshots provide a mechanism for backup that does not require downtime, there are
some considerations that should be given when performing backup and restore of a system
using snapshots. HP recommends you review this section prior to establishing backup and
restore policies. Backup and Restore programs are not trivial applications. As such they
require effort to set up and use effectively. Given the nature of these products, it is critical that
any backup and recovery plan be thoroughly tested before use on a live system.

Be sure to use a backup program that is PSM aware and has been certified for operation with
PSM. This is especially true for open file options, system agents, and disaster recovery.

For backup:

■ For base volumes that have snapshots in use or when backing up snapshots, archive bit

resets and incremental backups should not be used. Archive bit resets are recorded as a
change to the data and can fill the cache file with changes. Incremental backups make use
of the archive bit set as well. Note if the snapshot is set to read only the backup will also
fail.

■ Be careful in the selection of folders, since snapshot folders provide a view into the data

that can result in the backup of multiple views of the data. Forcing the backup to grow
based on the number of snapshots in use.

■ Junction points should be turned off to prevent the traversal of multiple snapshot

directories of base volume backups.

■ Junction points should be turned on when backing up a single snapshot. Be sure to pick the

single snapshot and not the root folder. Selecting the root folder will cause multiple
snapshot backups.

42 NAS 1000s Administration Guide

For restore:

■ Delete all active snapshots as the restore will cause the cache file to grow.

■ Select only the files representing the data of the volume and not the *.psm files.

■ Be sure to restore to the root of the target volume.

■ Restoration of operating system partitions does not restore the registry hive. System state

backups should be utilized in these instances.

Snapshots Performance Impact

When using snapshots, performance of the disk may be affected, depending on the rate that
data is changing and the number of snapshots kept for each disk. Read performance of the disk
remains constant, regardless of the presence of snapshots. Read performance of the snapshot is
identical to that of the disk. Write performance, however, may vary. PSM creates minimal
additional I/O overhead which is limited to writes. The copy-on-write process adds one read
(the write is paused to read the old data) and one write (the old data is written to the Diff
Directory file) to each write system request. This only affects each initial write to a disk area
that has a snapshot running on it. Copy out is not performed on subsequent writes to the same
disk block, so write performance is unaffected after the initial write to each block.

Predicting the exact effect of snapshots on any particular disk is difficult, because several
variables are involved. These variables include the type of applications accessing the data and
the rate of change of the files on the disk. When a high percentage of writes is made to the
same area, as when a file is constantly rewritten, the effect is called write locality. Disks with
high write locality experience less performance degradation due to snapshots.

Persistent Storage Manager

Recovering Snapshots after a System Restore or System Loss

The NAS 1000s ships with a Quick Restore DVD in case the server must be restored to its
factory default state. If the primary operating system becomes corrupted and unaccessable,
registry information for existing snapshots are lost. Volume data remains unaltered and
accessable using the secondary OS. However, the snapshots are invalid. Even though all
snapshot folders and cache files exist on the system volumes, the snapshots are not accessible
to PSM in the secondary OS, and are orphaned. At this time, the user should backup all data
by booting using the secondary OS and then restore the system to it's factory default state
using the included Quick Restore DVD.

Caution: Performing a quick restore prcedure using the Quick Restore DVD will delete all

data on all drives in the system.

43NAS 1000s Administration Guide

Persistent Storage Manager

Granule Size Update Utility

PSM ships with a utility for adjusting the Granule size of the snapshots. Granules determine
the largest cache size that can be managed by PSM. The default setting in the PSM product
that ships on the NAS 1000s is 64 K. This setting will allow for up to 1 TB of data to be
written to the cache file. In order to gain greater cache file space, the granule size will need to
be adjusted. The following table provides an overview of the addressable storage space and
maximum cache size of each Granular size.

Table 2: Adjusting Granule Size

Granule Size Largest Cache Size

64K granule 1 TB
128K granule 2 TB
256K granule 4 TB

When considering the granule size the following rules should be observed.

■ Before altering the granule size, all snapshots should be removed from the target system.

■ Cache File size is fixed as in the above table and the limit applies to the sum total of all

cache files system wide.

■ Granule size affects only the block size utilized for each change that is written to the cache

files. Regardless of the setting, there is approximately 15.6 million blocks available for
storing snapshot information system wide other system limitations may further limit this
maximum such as memory consumption.

■ If the changes occur in different underlying blocks, more blocks of larger space could get

written for any set of changes, versus if the changes all occur in the same block. Therefore
increased granule size does not necessarily lead to increased coverage for changes on the
originating volumes. In theory, larger blocks should lead to fewer blocks consumed to
record the original data due to write locality.

■ Highly fragmented disk space could lead to increased separate cache writes and more

consumption of the maximum available number of blocks system wide.

■ Setting the value too low will limit the available space for cache file writes. For example, a

10 TB system undergoing change could only experience a 10 % change in original data if
the granule size is set to 64 KB, assuming all of the changes fit neatly into the 64KB
blocks.

■ PSM now supports the PSM granule sizes of 64K, 128K, 256K with 64K as the default.

This will allow for cache file to be 1TB, 2TB, and 4TB respectively. The program
GRANSIZE.EXE, available in the directory c:\winnt\system32\serverappliance, is
provided for setup - By increasing the granule size, PSM can be better suited to support
very large terabyte systems. The command provides an error message if there are running
snapshots on the system. Typing GRANSIZE ? will display the current granule size in use
in the system. Typing just GRANSIZE will display the command usage. The command
must be executed from a command prompt while residing in the directory stated above.

44 NAS 1000s Administration Guide

■ When changing to a larger granule for systems, thus allowing for larger cache file sizes

and accommodating larger amounts of storage, users should lower their percentage of
volume space for the cache file. For example, if the percent is 30 and the supported
amount of space in the system is 20 TB, then the cache file limit of 4 TB would get
exceeded. Should the limit get exceed, PSM will issue an "Out of Memory" error in the
event log and the WebUI status page. If the limit is exceeded, the cache file must be
removed or reduced in size prior to system restart using either the clearvol command or by
reducing the percent cache size under volume settings.

Clearing the Cache File from the System

The PSM interface allows the user to set the cache file to any percentage from 1 - 70 percent
but it will not allow the deletion of the cache file in its entirety. It is possible to delete these
files but the process must be done from the command prompt either through Terminal Services
or from the NAS console. To delete the PSM cache files and cache directories the following
command: CleanVol.exe Vol: must be performed for each existing volume where the cache file
is no longer desired. The command may be found in c:\winnt\system32\serverappliance.
Typing cleanvol will display the command usage. Prior to these steps the snapshots on the
target volume need to be deleted as well or "access denied" error will be returned.

Persistent Storage Manager

Re-extending Volumes from Old Snapshots

Volumes based on dynamic disks may be extended utilizing LDM. Corresponding snapshots
can exist at points in time prior to the extension and after the extension. If a re-extended
volume containing snapshots of the pre-extended volume is reverted, the re-extended area of
the disk will be unusable. To reclaim this space, make sure the included utility reextend.exe is
executed after reverting from a snapshot of the pre-extended volume.

This utility is available in the directory c:\winnt\system32\serverappliance and must be
executed either through terminal services or at the NAS console.

Usage of this utility is available by typing reextend -?.
This program will extend a volume back to its original size after a restore operation of a

smaller volume from a snapshot.

Volume Display in Persistent Storage Manager

PSM fully supports the use of all Logical Disk Manager storage elements this includes basic,
dynamic, partitions, extended partitions, and volumes provided they are formatted as NTFS
when created. PSM makes use of two items when displaying storage elements in the UI. These
include the volume label and the GUID representing that volume or partition. In several web
pages, the information displayed is limited with regard to the identification information and
the volume label is essentially all that can be viewed. It is therefore important that volume
labels be identifiable by the user to avoid confusing one volume over another. By default,
Local Volume, followed by the drive letter is displayed, for mount points the GUID is
displayed. This label should be updated to reflect a unique label either during volume/partition
creation in LDM or post volume/partition creation via File Explorer and the properties tab of
the target drive.

Persistent Storage Manager Storage Limitations

The version of PSM included in the NAS 1000s is currently designed to work with 10 TB of
storage with the ability to take 250 snapshots The NAS 1000s is capable of addressing 1TB
using the fully populated system and 250 GB Drives. PSM will continue to function with
larger systems but the snapshot coverage should only encompass 10 TB worth of storage.
There are no safeguards to prevent the use of storage greater than 10 TB. HP is currently
working with CPD to address this storage limitation. Please check the HP website for updates

Maximum Persistent Images

This option determines the maximum number of active Persistent Images (snapshots). PSM
will support a maximum of 250 snapshots per server. The size of the cache file will determine
the actual amount each server can hold.

If the creation of a new snapshot would cause the maximum number to be exceeded, the
system will delete the oldest existing persistent image according to the deletion heuristics
established by the user.

Inactive Period

This option specifies the amount of time a volume must be dormant before a snapshot is
created. Before starting a snapshot, the system will wait for the volume being imaged to
become inactive. The default value will allow systems to start an image with a consistent file
set and a minimal time-out. Administrators can change this value for system optimization.
Reducing the inactive period will allow you to create snapshots even on busy systems, but with
possible synchronization problems within applications which are concurrently writing to
multiple files.

47NAS 1000s Administration Guide

Inactive time-out

This option specifies how long the server should try to create a snapshot. A snapshot will not
begin until a period of relative inactivity set by the Inactive period has passed. If an interval
passes that is longer than the Inactive time-out period, the snapshot will not be created and a
notice generated to the system event log.

Known Issues

These were the known issues at time of publication. Please refer to the release notes for the
NAS 1000s for updated information regarding known issues.

Event log error at cache full

The eventlog error a driver below this one has failed in some way may occur when the cached
file is full.

Display Error on SAK

Status events not rendered properly on SAK. The percent signs not displayed value
substitutions missing in displayed message

Always Keep error at cache file full

If all your snapshots on C:\ are tagged as Always Keep and the cache file fills up, the system
may experience a BSOD at reboot.

It is not recommended to flag all snapshots as Always Keep because this disallows the PSM
deletion logic to delete the older snapshots to free up cache file space.

Improper display of default Cache File Size

You must delete all snapshots before changing the cache size.

Page file setting

The Page file size must not change and the initial size must be set equal to the maximum size.
This setting is located in the Virtual Memory settings under System Properties.

No Boot - No Revert

If the system cannot boot, a revert operation cannot be performed.

Reverting of System Drive Prohibited

PSM does not allow the ability to revert the system boot drive.

No support for mount points in UNIX, AppleTalk, or NetWare

Microsoft confirmed that the Microsoft NFS Services for UNIX, Services for Macintosh, and
Services for NetWare do not support volume mount points. These clients will not be able to
access data on volumes mounted using a volume mount point. Since snapshots for a volume
are mounted as directory junctions (AKA mount points), and even though they are shared
these clients will not be able to access the snapshots.

Please refer to the Microsoft Release Notes for Microsoft Server Appliance Kit dated June

2001.

62 NAS 1000s Administration Guide

User and Group Management

The HP StorageWorks NAS 1000s supports a variety of file sharing protocols for file access
over a network, including:

■ Common Internet File System (CIFS)

■ Network File System (NFS)

■ Novell Core Protocol (NCP)

■ AppleTalk (AFP)

Access to shares requires a network logon (username and password). It follows that a
fundamental part of managing shares involves managing the users and groups that have access.

There are two system environments for users and groups: workgroup and domain. Because
users and groups in a domain environment are managed through standard Windows NT or
Windows 2000 domain administration methods, this document discusses only local users and
groups, which are stored and managed on the NAS device. For information on managing users
and groups on a domain, refer to the domain documentation.

User and Group Management

Domain Compared to Workgroup Environments

NAS 1000s devices can be deployed in workgroup or domain environments. When in a
domain environment, the server is a member of the domain. The domain controller is a
repository of accounts and account access for the NAS 1000s. Client machines are also
members of the domain, and users log on to the domain through their Windows clients. The
domain controller also administers user accounts and appropriate access levels to resources
that are a part of the domain.

In a CIFS environment, when mapping a network drive or a client machine, a user sends a
logon credential to the server. This credential includes the username, password, and if
appropriate, domain information. Using the credential, the server authenticates and provides
the corresponding access to the user.

When a NAS 1000s is deployed into a workgroup environment, all user and group account
access permissions to file resources are stored locally on the server.

By contrast, when a NAS 1000s is deployed into a domain environment it uses the account
database from the domain controller, with user and group accounts stored outside the server.
The server integrates with the domain controller infrastructure.

Note: The NAS 1000s cannot act as a domain controller for other servers on the network. If user

and group account information is stored locally, those accounts may be used only to authenticate
logons to the NAS 1000s, resulting in a workgroup configuration.

Administering users and groups in a domain environment is similar in a mechanical sense to
administering them in a workgroup environment. If using an Active Directory domain
controller, the Computer Management tool allows for adding, modifying, and removing users
in the same context as in a workgroup environment. The concepts, however, are very different.

Additional information about planning for domain environments can be found at:

http://www.microsoft.com/windows2000/technologies/directory/ad/default .a s p

The configuration of the domain controller is reflected on the NAS 1000s because it obtains
user account information from the domain controller when deployed in a domain environment.
As mentioned previously, the server cannot act as a domain controller itself.

User and Group Name Planning

Effective user and group management is dependent upon how well the user and group names
are organized. Administrators typically create a small number of groups on the network and
then assign users to the appropriate group or groups. File system and share permissions can
then be applied at the group level, rather than at the user level. If the number of groups is
small, assigning the appropriate permissions to selected group, or groups, is more efficient
than assigning permissions to each user.

Although each organization has specific conventions, following general guidelines makes
administration simpler and more efficient. Because CIFS is dependent on users and groups to
grant appropriate access levels to file shares, CIFS administration benefits from a consistent
user and group administration strategy.

64 NAS 1000s Administration Guide

Managing User Names

Usernames should reflect a logical relationship between the username and the person who uses
the account. It is important that rules are established to ensure that usernames are:

■ Systematic

■ Easy to follow and implement

■ Easy to remember

Using a combination of the user's first name, middle initial, and last name results in systematic
usernames for every member of a particular organization. Common examples include:

■ First initial followed by last name (jdoe for John Doe)

■ First initial followed by middle initial and last name (jqpublic for John Q. Public)

■ First name followed by last name, separated by a period (john.smith for John Smith)

■ Last name followed by first initial (doej for Jane Doe)

Guidelines must be in place for instances when two users have the same initials or name. For
example, a number can be added to the end of the username (jdoe1 and jdoe2).

Other conventions can be applied. Just ensure that conventions are both systematic and
consistent.

User and Group Management

Managing Group Names

Group management follows many of the same principles as user management.
It is recommended that group naming conventions be systematic and easy to understand. Make

the group name convey some logical information about the function or purpose of the group.

Tabl e 3 provides examples of group names.

Table 3: Group Name Examples

Group Name Description

Administrators All designated administrators on the server
Users All standard server users
Power users All standard server users requiring advanced access levels

Using tags is a helpful convention that indicates the specific access that a particular user has to
a network resource. For example, if there is a data share on the device, the network
administrator can create a "Data Users ROnly" group and a "Data Users RWrite" group to
contain users that have read only or read write access on the share, respectively.

Drive Quotas

Drive quotas let administrators control the allocation of drive space to individual users or
groups of users. When quotas are enabled and properly configured, it is impossible for one
person or group to consume all of the available space on a disk.

When quotas are enabled on a volume that already contains files, the system calculates the
drive space used by all users on the volume. The quota limit and warning level are then applied
to all current users. Administrators can then modify quotas as needed. By enabling and then
disabling quotas, administrators take advantage of the auditing capabilities provided by
quotas, without reducing server performance.

Managing Quotas

Managing quotas includes:

■ Enabling and disabling quota management

■ Creating new quota entries for a user or group

■ Deleting quota entries for a user or group

■ Modifying quota entries for a user or group

Each of these tasks is discussed in the following sections.

Folder and Share Management

The HP StorageWorks NAS 1000s supports several file sharing protocols, including CIFS,
NFS, FTP, HTTP, NCP, and AFP (AppleTalk). This chapter discusses overview information as
well as procedural instructions for the setup and management of the file shares for the
supported protocols. In addition, discussions on security at the file level and at the share level
are included in this chapter.

Abbreviated information on creating NFS file shares is included in this chapter; for detailed
information on setting up and managing NFS file shares, see Chapter 6, UNIX File System
Management.

NCP shares must be set up and managed through the NAS Management Console user
interface. For information on managing NCP file shares, see Chapter 7, NetWare File System
Management.

Folder Management

Volumes and folders on any system are used to organize data. Regardless of system size,
systematic structuring and naming conventions of volumes and folders eases the
administrative burden. Moving from volumes to folders to shares increases the level of
granularity of the types of data stored in the unit and the level of security access allowed.

Although a variety of methods can be used to create and manage file folders on the NAS
1000s, this document discusses using the NAS Web based user interface (WebUI.)

Managing system volumes and file folders includes the following tasks:

■ Navigating to a specific volume or folder

■ Creating a new folder

■ Deleting a folder

■ Modifying folder properties

■ Creating a new share for a volume or folder

■ Managing shares for a volume or folder

■ Managing file level permissions

80 NAS 1000s Administration Guide

Navigating to a Specific Volume or Folder

When you work with volumes and folders, the first task is to gain access to the desired volume
or folder.

The steps are the same, whether navigating to a volume or a folder:

1. To navigate to a specific volume or folder, from the WebUI, select Shares and then
Folders. Initially, the Vol um e s dialog box is displayed.

This initial dialog box displays all system volumes.

Folder and Share Management

Figure 38: Volumes dialog box

2. From this dialog box, navigate to a specific folder by selecting the appropriate volume and
then clicking Open. The Folders dialog box is displayed, with a list of all of the folders
within that volume.

3. To navigate to a subfolder, select the folder in which the subfolder resides, and then click
Open. Repeat this searching and opening process until the desired folder is opened. See

Figure 39 for an example of Folders dialog box.

81NAS 1000s Administration Guide

Folder and Share Management

Figure 39: Folders dialog box

After accessing the desired folder, the following actions can be performed:

■ Creating a new folder

■ Deleting a folder

■ Modifying folder properties

■ Creating a new share for the volume or folder

■ Managing shares for the volume or folder

Creating a New Folder

To create a new folder:

1. From the Shares directory, navigate to the Folders menu and then select New. The Create
New Folder dialog box is displayed.

Two tabs are displayed: General and Compress. Use these two tabs to enter the
parameters for the new folder.

2. In the General tab, enter a name for the folder and specify the folder attributes.

82 NAS 1000s Administration Guide

Folder and Share Management

Figure 40: Create a New Folder dialog box, General tab

3. In the Compress tab, indicate whether and how this folder and its contents are to be
compressed.

4. After all information for the new folder is entered, click OK.

Deleting a Folder

To delete a folder:

1. From the Shares directory, navigate to the folder to delete. Select the folder and then click
Delete. The Delete Folder dialog box is displayed.

Summary information about the deletion is displayed.

Note: View the summary information to confirm that this is the intended share.

2. Verify that the displayed folder is the folder to delete and then click OK.
The folder and all of its subfolders are deleted and the main dialog box is displayed again.

■ Folder Name

■ Folder Attributes

3. In the Compress tab, indicate whether and how this folder and its contents are to be
compressed.

4. After all changes have been completed, click OK. The Folders dialog box is displayed
again.

Creating a New Share for a Volume or Folder

Within the WebUI, there are two access points to the same screens used to create file shares:

■ A share can be created for a folder while working with that folder in the Folders screens.

■ A share can be created and, if necessary, new folders can be created, while working with

file shares in the Shares screens.

This section discusses creating shares from the Folders menu, and is an overview of the
procedures. Complete details on the process of creating shares are included in the discussion
that documents creating shares through the Shares menu. See the "Managing Shares" section
of this chapter for these details.

To create a new share for a specific volume or folder while in the Folders menu:

1. Navigate to the desired volume or folder and click Share. The Create New Share dialog
box is displayed.

84 NAS 1000s Administration Guide

Folder and Share Management

Figure 42: Create New Share dialog box, General tab

2. Enter the information for the share, including the name of the share, the allowed protocols,
and corresponding permissions.

Note: The Share path is the path of the previously selected volume or folder. This field is

automatically completed by the system.

3. Select the appropriate tab to enter protocol specific information.
See the "Managing Shares"section for detailed information about these entries.

4. After entering all share information, click OK.

Managing Shares for a Volume or Folder

Within the WebUI, there are two access points to the same screens used to manage file shares:

■ While working with a folder in the Folders dialog boxes, the administrator can create,

delete, and modify shares for that folder.

■ While working with file shares in the Shares dialog boxes, the administrator can create,

delete, and modify shares (and if necessary, create new folders).

Note: This section discusses managing shares from the Folders menu, and is an overview of the

procedures. Complete details on the process of managing shares are included in the discussion that
documents creating shares through the Shares menu. See the "Managing Shares" section later in
this chapter for these details.

85NAS 1000s Administration Guide

Folder and Share Management

To create, delete, and manage shares for a particular volume or folder while in the Folders
menu:

1. From the Folders directory, navigate to the target volume or folder and click Manage
Shares. The Shared Folders dialog box is displayed.

All associated shares for that folder or volume are listed.

2. To create a new share, click New. The Create a New Share dialog box is displayed.
Because the screens are the same whether shares are managed through the Folders menu

or the Shares menu, the procedures are only documented once. See "Creating a New
Share" in the "Share Management" section for detailed procedural instructions on creating
new file shares.

3. To delete a share, select the share to delete and click Delete. The Delete Share dialog box
is displayed.

Because the screens are the same whether shares are managed through the Folders menu
or the Shares menu, the procedures are only documented once. See "Deleting a New
Share" in the "Share Management" section for detailed procedural instructions on deleting
file shares

4. To modify share properties, select the share to modify, and click Properties. The Share
Properties dialog box is displayed.

Because the screens are the same whether shares are managed through the Folders menu
or the Shares menu, the procedures are only documented once. See "Moifying Share
Properties" in the "Share Management" section for detailed procedural instructions on
modifying shares.

Managing File Level Permissions

The WebUI of the NAS 1000s provides security at the share level and is discussed later in this
chapter. Security at the file level is managed using Windows Explorer available from the
desktop of the NAS 1000s. To access the NAS 1000s Console from the WebUI, go to the
Maintenance menu and select Terminal Services.

File level security includes settings for permissions, ownership, and auditing for individual
files.

To enter file permissions:

1. Using Windows Explorer, navigate to the folder or file that needs to be changed and then
right-click the folder.

2. Select Properties and then select the Security tab. Figure 43 illustrates the properties
available on the Security tab.

Several options are available in the Security tab dialog box:

■ To add users and groups to the permissions list, click Add. Then follow the dialog box

instructions.

■ To remove users and groups from the permissions list, highlight the desired user or group

and then click Remove.

■ If the Allow inheritable permissions from parent to propagate to this object box at the

bottom of the screen is checked, the file or directory inherits permissions from the parent
directory. In this case, existing user and group permissions cannot be changed; however,
additional users or groups can be added.

■ The center section of the Security tab provides a listing of permission levels. When new

users or groups are added to the permissions list, select the appropriate boxes to configure
the common file access levels.

Note: Selections can be made when the Allow inheritable permissions from parent to propagate

to this object box is disabled.

■ To modify ownership of files or to modify individual file access level permissions, click

Advanced.

Folder and Share Management

The final tab in the advanced Advanced Access Control Settings security configuration is the
Owner tab. This tab allows for taking ownership of files. Typically, administrators use this

area to take ownership of files when the file ACL is incomplete or corrupt. By taking
ownership, you gain access to the files and then manually apply the appropriate security
configurations. Figure 49 illustrates the Owner tab.

Share Management

There are several ways to set up and manage shares. The WebUI provides screens for setting
up and managing shares. Additional methods include using a command line interface,
Windows Explorer, or NAS Management Console. This guide demonstrates using the WebUI
to set up and manage shares.

As previously mentioned, the file sharing security model of the NAS device is based on the
NTFS file-level security model. Share security seamlessly integrates with file security. In
addition to discussing share management, this section discusses share security. See "Managing
File Level Permissions" earlier in this chapter for information on file security.

Shares management topics include:

■ Share Considerations

■ Defining Access Control Lists

■ Integrating Local File System Security into Windows Domain Environments

■ Comparing Administrative and Standard Shares

■ Planning for Compatibility between File-Sharing Protocols

■ Managing Shares

Share Considerations

Planning the content, size, and distribution of shares on the NAS 1000s can improve
performance, manageability, and ease of use.

The content of shares should be carefully chosen to avoid two common pitfalls: either having
too many shares of a very specific nature or of having very few shares of a generic nature. For
example, shares for general usage are easier to set up in the beginning, but can cause problems
later. Frequently, a better approach is to create separate shares with a specific purpose or group
of users in mind. However, creating too many shares also has its drawbacks. Take care to avoid
creating shares unnecessarily. For example, if it is sufficient to create a single share for user
home directories, create a "homes" share rather than creating separate shares for each user.

By keeping the number of shares and other resources low, the performance of the NAS 1000s
is optimized. For example, instead of sharing out each individual user's home directory as its
own share, share out the top level directory and let the users map personal drives to their own
subdirectory.

Defining Access Control Lists

The Access Control List (ACL) contains the information that dictates which users and groups
have access to a share, as well as the type of access that is permitted. Each share on an NTFS
file system has one ACL with multiple associated user permissions. For example, an ACL can
define that User1 has read and write access to a share, User2 has read only access, and User3
has no access to the share. The ACL also includes group access information that applies to
every user in a configured group. ACLs are also referred to as permissions.

92 NAS 1000s Administration Guide

Folder and Share Management

Integrating Local File System Security into Windows Domain Environments

ACLs include properties specific to users and groups from a particular workgroup server or
domain environment. In a multidomain environment, user and group permissions from several
domains can apply to files stored on the same device. Users and groups local to the NAS 1000s
can be given access permissions to shares managed by the device. The domain name of the
NAS 1000s supplies the context in which the user or group is understood. Permission
configuration depends on the network and domain infrastructure where the server resides.

File-sharing protocols (except NFS) supply a user and group context for all connections over
the network. (NFS supplies a machine based context.) When new files are created by those
users or machines, the appropriate ACLs are applied.

Configuration tools provide the ability to share permissions out to clients. These shared
permissions are propagated into a file system ACL and when new files are created over the
network, the user creating the file becomes the file owner. In cases where a specific
subdirectory of a share has different permissions from the share itself, the NTFS permissions
on the subdirectory apply instead. This method results in a hierarchical security model where
the network protocol permissions and the file permissions work together to provide
appropriate security for shares on the device.

Note: Share permissions and file level permissions are implemented separately. It is possible for files

on a file system to have different permissions from those applied to a share. When this situation
occurs, the file level permissions override the share permissions.

Comparing Administrative (Hidden) and Standard Shares

CIFS supports both administrative shares and standard shares. Administrative shares are
shares with a last character of $. Administrative shares are not included in the list of shares
when a client browses for available shares on a CIFS server. Standard shares are shares that do
not end in a $ character. Standard shares are listed whenever a CIFS client browses for
available shares on a CIFS server.

The NAS 1000s supports both administrative and standard CIFS shares. To create an
administrative share, end the share name with the $ character when setting up the share. Do not
type a $ character at the end of the share name when creating a standard share.

Planning for Compatibility between File Sharing Protocols

When planning for cross-platform share management on the NAS 1000s, it is important to
understand the different protocols and their associated constraints. Each additional protocol
that is supported adds another level of constraints and complexity.

NFS Compatibility Issues

Of the file sharing protocols that are supported on the NAS 1000s, NFS introduces the most
constraints. When planning to manage CIFS and NFS shares, consider two specific
requirements.

Note: Further information, including details about the NFS Service and the User Mapping service, is

available in Chapter 6, UNIX File System Management.

93NAS 1000s Administration Guide

Folder and Share Management

■ NFS service does not support spaces in the names for NFS file shares.

NFS translates any spaces in an export into an underscore character. Additional
translations can be set up for files. See the "OEM Supplemental Help" chapter of the SFU
help, found on the NAS 1000s. This feature is designed to ensure the greatest level of
compatibility with NFS clients, because some do not work with NFS exports that contain a
space in the export name.

If you plan to use the same name when sharing a folder through CIFS, and then exporting
it through NFS, do not put spaces in the CIFS share name.

■ NFS service does not support exporting a child folder when its parent folder has

already been exported.
An NFS client can access a child folder by selecting the parent folder and then navigating

to the child folder. If strict cross-platform compatibility is an administration goal, CIFS
must be managed in the same way. Do not share a folder through CIFS if the parent folder
is already shared.

Managing Shares

Shares can be managed through the Shares menu option of the WebUI. Tasks include:

■ Creating a new share

■ Deleting a share

■ Modifying share properties

Each of these tasks is discussed in this section.

Folder and Share Management

Select one of the following caching policies:

■ Manual Caching for Documents—The default setting. Recommended for folders

containing user documents. Users must manually specify any files that they want available
when working offline. To ensure proper file sharing, the server version of the file is always
open.

■ Automatic Caching for Documents—Also recommended for folders containing user

documents. In contrast to the default setting of Manual Caching, with this option, open
files are automatically downloaded and made available when working offline. Older
copies are automatically deleted to make room for newer, more recently accessed files. To
ensure proper file sharing, the server version of the file is always open.

■ Automatic Caching for Programs—Recommended for folders with read only data or run

from the network applications. File sharing is not ensured. Open files are automatically
downloaded and made available when working offline. Older copies are automatically
deleted to make room for newer, more recently accessed files.
