Physical Drives

The HP NetStorage 6000 contains between four and ten physical hard drives, depending on your company’s storage needs. Each physical drive can have up to 73GB of storage capacity.

Figure 1.1 P hysical Driv es

1-3

Note Use only HP Hard Drives approved for your NetStorage 6000. For an up-

to-date list of approved hard disk drives, please visit our web site at www.hp.com/support /ns6000. Drives on the appr oved list have custom firmware for use in your NetStorage 6000. Do not attempt to install any hard disk drives other than the approved drives listed at this web site as doing so may resu lt i n system failure or loss of dat a. U s i ng non -s upported hard drives may also void your warrant y.

Note All drives in the HP NetStorage 6000 must have the same capacity. Any

other configuration is not supported.

Logical Drives

Figure 1.2 Logical Drives

Overview

HP NetStorage 6000 Hardware

Physical drives are grouped together to form one or more logical drives, which are also known as RAID sets. Physical drives are also used individually as hot spares. Logical drives and hot spares are configured at the factory. The illustration in figure 1.2 shows a typical configuration.

Note The HP NetStorage 6000 supports only RAID level 5 for the creation of

logical drives. Because RAID level 5 requires a minimum of 3 physical drives for a RAID set, the HP NetStorage 6000 requires at least 3 drives to be grouped together to create a logical drive, though you can create a logical drive that uses as many as eight physical drives.

1-4

Overview

HP NetStorage 6000 Hardware

Partitions and File Volumes

Logical drives are further broken down into as many as four partitions with each partition consisting of 256GB of drive space or less. Once you have partitioned your logical drive, you can create file volumes for storing your data.

File volumes are the basic unit of logical stora ge for a file system on the HP NetStorage 6000. When you create a file volume, it uses one partition on one logical drive. Because you are limited to fou r partitions, the max imum number of file volumes that can be created on a logical drive is four.

Note The HP NetStorage 6000 has a limit of 256GB (262144 MB) per partition.

The user interface does not warn you of this limitation. If you attempt to create a partition greater than 256GB, the operation fails.

Initially, each partition is assigned to a file volume. However , file volumes can expand to span several partitions if extra storage space becomes necessary.

Figure 1.3 File Volume and Partition Example

1-5

The illustration in figure 1.3 on page 1-5 shows a logical drive that consists of three physical drives. This logi cal drive has b een broken down i nto four partitions (the maximum number). Typically , you create partitions such that each one becomes a file volume. However, at some point you may r e quire more storage space for a file volume.

Increasing Storage Capacity

An important aspect of ma naging file vo lumes is the con cept of expan ding volumes. If, at a later date, a file volume becomes full of data, you can expand the file volume, thus alleviating the lack of space on the volume. Just like creating new file volumes, expanding file volumes need storage space from a logical drive, and a free partition. However, this free space and free partition do not have to be on the same logical drive as the file volume that is being expanded. Thus, it is possible to create file volumes that span across logical drives. This gives you the option of expanding existing volumes by installing another logical drive on the system.

The example shown in figure 1.4 on page 1-7 expands on the previous example by adding a new logical drive consisting of five newly added physical drives. This logical drive has had one partition defined. File volume 3 has then been expanded to include this newly available space.

Hot Spare Drives

Hot spare drives are reserved drives that are used only when a physical drive that is part of a logical drive fails. When this happens, the system automatically selects the first available hot spare drive to take the place of the failed drive as shown in figure 1.5. The logical drive is rebuilt using the hot spare, and the hot spare drive becomes a member of the logical drive.

Figure 1.5 Hot Spare Drive

Overview

HP NetStorage 6000 Hardware

It is important to note that a hot spare must have the same or larger capacity of the physical drive it is to replace. The system will not select a hot spare to replace a failed drive if the capacity of the hot spare is less than the dr ive it is to replace.

Once a hot spare is used to repair a logical drive, its assignment changes from Hot Spare to Online. If you replace the failed drive, it automatically receives an assignment of Unassigned. You must manually assign the new drive to Hot Spare if the new drive is to serve as a hot spare.

Redundant Power Supply Modules

A redundant power supply module is installed in the back of the HP NetStorage 6000. Three power -suppl y modules are acti ve but only t wo are necessary to power a fully loaded unit. If a power supply module fails, the redundant supply provides power to t he unit.

1-8

Overview

The HP NetStorage 6000 Web Interface

Redundant Power Supply Cords

The HP NetStorage 6000 lets you attach more than one power source into the back of the unit. This redundancy protects against a power failure. The primary power cord needs to be connected when power is turned on.

The HP NetStorage 6000 Web Interface

The HP NetStorage 6000 is managed via a web browser as shown in figure 1.6 on page 1-10 (Internet Explorer 5.0 or later or Netscape 4.61 or later). To access the web interface, enter the IP address of the HP NetStorage 6000 in the address field of your browser.

Note The first time you open this interface, a security warning appears. The

NetStorage web interface uses Java an d Javascript co mponents to prop erly display system information.

Backing up the HP NetStorage 6000

Local Backup

Y ou can use the backup app lication in the NetStorage web interface plus an optional HP SureStore DLT Autoloader 818 or 1/9 to perform a local backup. In a local backup session the data is transferred to the locally attached Autoloader using a tape format that is unique to the HP NetStorage

6000. The data transfer does not interfere with your LAN traffic.

Remote Backup

You can use third-party backup applications on any computer on the network with a tape drive attached to perform a remote backup. When you run a remote backup, data from the HP NetStorag e 6000 tran sfers over the network to the remote server running the backup application, and then to the server-attached tape device.

T ape backup is intended to replace the data of an entire drive. It is possible to restore individual files, but only if you know the exact location of a file.

For a list of remote backup applications the HP NetStorage 6000 integrates with, see Chapter 11, “Integrating with Remote Backup Applications.”

Logical drives on the HP NetStorage 6000 are roughly equivalent to what is commonly referred to as a RAID set. Y ou may par tition the storage space on logical drives to create up to four file volumes. You may want to view logical drive information to see how much free space is available in the individual partitions, and where you might want to save your data.

To manage and view logical drive information:

Using the NetStorage web interface, click the Storage tab, then select Logical Drives.

A table displays partition information for each logical drive in the system. To the left of the table, the following drive information displays:

n Drive name n Drive capacity n RAID level n Drive status

The table contains partition information for the logical drive. Each logical drive contains a maximum of four partitions. Partitions are allocated to create file volumes. The table displays the current allocation of partitions to the file volumes on the system, and contains the following information:

4-3

n Partition number (1 through 4) n File volume name n Raw capacity (unformatted capacity dedicated to the file volume) n Percent of total space used by the partition

Partitions that are available for the creation of new file volumes display <FREE SPACE> in the File Volume Name column, and show the maximum available free space in the Raw Capacity column.

Note The Actions button in the upper left corner lets you create, rename,

expand, and delete file volumes.

Create a Logical Drive

You create logical drives by grouping a set of phys ical drives into a sing le RAID set. Currently, the HP NetStorage 6000 supports only RAID level 5 for the creation of logical drives. Because RAID level 5 requires a minimum of three physical drives for a RAID set, the HP NetStorage 6000 requires at least three drives to be grouped together to create a logical drive.

To create a new logical drive:

1 Using the NetStorage web interface, click the Storage tab, then select

Physical Drives.

2 Click Actions, then select Create Logical Drive. All of the physical

drives in the system are displayed. Each drive is represented by a graphic of a drive bay:

• Drive bays containing unassigned drives are selectable.

• Drive bays that are empty, or that contain assigned drives are not

selectable.

The drive is prepared in three stages:

1 The command is issued to the RAID controller. 2 The RAID controller activates the new logical drive. 3 The logical drive is initialized.

The first two steps execute quickly and are typically completed within a minute. After these two steps are complete, the new Logical Drive is ready to use. At this point, you may create volumes and place data on those volumes. You do not need to wait for the third step to run to completion.

Managing Physical and Logical Drives

Drive Initialization, the third and final step of Logical Drive creation, takes place in the background and may be time-consuming. Th is process shou ld run to completion before t he system is re-booted or powered down. In order for the system to track the process, other RAID-related operations, such as Hot Spare assignment, are not allowed until this process is complete.

Note A logical drive may contain a maximum of eight physical drives.

Delete a Logical Drive

When you delete a logical drive, the physical drives it used are set to the unassigned state. It is i mportant to note thoug h, that you can onl y delete the last logical drive in the list. For example, if two logical drives exist on the system, in order to delete the first logical drive, you must first delete the second logical drive.

To delete a logical drive:

1 Using the NetStorage web interface, click the Storage tab, then select

Physical Drives.

2 Click Actions, then select Delete Logical Drive.

Rebuild a Logical Drive (RAID set)

If a physical drive in a logical drive fails and a hot spare is not available to automatically replace it, the logical drive goes into a critical state. In this state, the logical drive does not protect the data with redundancy. All data on the logical drive is lost if another drive fails.

Note If you replace a failed drive with a new drive, you must use the same slot

that the failed drive used.

To recover the logical drive from critical state, replace the failed hard drive with a new one and rebuild the logic al drive:

1 Replace the failed drive. (Follow the instructions that come with the

drive.)

2 Using the NetStorage web interface, click the Storage tab, then select

Physical Drives.

3 Verify that the drive is recognized by the system. Click Actions, then

select Refresh to update the table. If the drive is not recognized (as unassigned), reboot the system.

4 Once the drive is recognized and is in an unassigned state, click

Assign a Hot Spare

The HP NetStorage 6000 l ets you as sign ph ysical drives to fu nction as hot spares. Hot spare drives are reserved drives that are used only when a physical drive that is part of a logical drive fails. When this happens, the system automatically selects the first available hot spare drive to take the place of the failed drive. The logical drive is rebuilt using the hot spare, and the hot spare drive becomes a member of the logical drive.

Once a hot spare is used to repair a logical drive, its assignment changes from Hot Spare to Online. If you replace the failed drive, it automatically receives an assignment of Unassigned. Y ou must manually assign the new drive to Hot Spare if the new drive is to serve as a hot spare.

Most systems only use one physical drive to serv e as a hot spare. However , there is no restriction on the number of hot spares in the system, though every additional hot spare uses another physical drive and lessens storage capacity. Any and all drives may serve as hot spares. There is no requirement to have a hot spare on the system at all.

To assign a hot spare:

1 Click the Storage tab, then select Physical Drives.

4-7

2 Click Actions, then select Assign Hot Spares. 3 A picture representing all of the physical drives in the system appears.

Each drive is represented by a graphic of a drive bay. Drive bays containing unassigned drives or hot spare drives are selectable. All other drive bays are not selectable.

4 Select the drives to be used as hot spares by clicking on them. 5 Click OK.

Note Refer to the HP support web page for more information on upgrading

storage capacity or replacing a failed hard drive.

Managing File Volumes and Directories

View File Volume Information

File Volumes are the basic unit of logical storage for a file system on the HP NetStorage 6000. The v olume contains a directory hierar chy that stores files within the directories of that hierarchy. You can manage directories and files from a remote UNI X or Windows system us i ng Explorer on Microsoft Windows, or by mounting the file volume from a UNIX shell. The HP NetStorag e 6000 also of fers a simpl e browsing tool that allows you to examine the hierarchy of each file volume o n the system, and to perform basic management functions.

To view file volume information:

1 Using the NetStorage web interface, click the Storage tab, then select

File Volumes. A tree list appears on the left. On the right, a file volume

summary screen appears. This summary screen displays the following general information for each volume on the system:

• File volume name

• Total capacity in MB

• Free space in MB

• Free space in percent

• Used space

2 Navigate the tree list to display more detailed information for each file

volume, and each subdirectory within the file volume. The root of the tree is an image of a computer, and is called Summary. Select this to display the summary page . File volumes are displayed in the second level of the tree hierarchy. Select a file volume to display a page that contains the following information:

Create a New File Volume

You create file volumes by allocating space from a logical drive. Logical drives on the HP NetStorage 6000 are divided into a maximum of four partitions. Whenever you create a file volume, it uses one partition on one logical drive.

To create a new file volume:

1 Using the NetStorage web interface, click the Storage tab, then select

Logical Drives.

2 Click Actions, then select Create File Volume. 3 Enter a new file volume name in the space provided. 4 Select a partition to use from the pull down menu.

4-9

5 Enter desired file volume size (MB) in the space provided. 6 Click OK.

A progress bar displays while the new volume is formatted.

Expand a File Volume

To expand a file volume, there must be free storage space and a free partition on a logical drive. This free space and free partition do not need to be on the same logical drive as the file volume to be expanded—you can create file volumes that span across logical drives. This gives you the option of expanding existing volumes b y installing another logical drive on the system.

To expand an existing file volume:

1 Using the NetStorage web interface, click the Storage tab, then select

Logical Drives.

2 Click Actions, then select Expand File Volume. 3 Select the volume to be expanded. 4 Select a partition to use from the pull down menu. 5 Enter desired file volume size in the space provided. 6 Click OK.

A progress bar displays while the file volume is expanded.

Managing Storage

Managing File Volumes and Directories

Delete a File V olume

When you delete a file volume, the space it u sed is reclaimed by the logical drive. However, if you delete a file volume that uses a partition number lower than a partition currently in use by another file volume, the freed space is not combined with the other free space on the logical drive.

For example, if partition 1 is deleted, and partition 2 contains a file volume, then the space freed up by partition 1 must remain as the fixed space of that partition. Partition 1 can still be used for a file volume, but the volume must allocate no more space than the volume that was deleted.

This restriction does not apply to deleted file volumes that are located in partitions adjacent to the remaining free space on the logical drive.

Caution Deleting a file volume destroys all the data on that volume. The p rocedure

cannot be reversed.

To delete a file volume:

1 Using the NetStorage web interface, click the Storage tab, then select

Allowing Access to Data

Create or Edit Windows Shares

Shares are permissions that let you control Microsoft Windows users’ access to data. You can create shares in 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.

Security for network shares is handled in one of two ways:

n Secure share level security is the simplest security method available.

Access to the share may be restricted on a share by share basis. The administrator can set Read Onl y pas swo rds and Read / Write passwords for each share on the system. Users wishing to gain acces s to a share are asked to supply the correct password. Only users with the correct password are given access to the share. Passwords are encrypted for transmission over the network lines.

n User level security is more advanced and offers more flexibility for

both the administrator and the user:

• Users are authenticated via the NT domain controller using pass

through authentication.

Managing Storage

Allowing Access to Data

• 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 r estrict acces s to any file, directory or

groups of files and directories to any user or group of users in the domain.

To create or edit shares in Windows:

1 Using the NetStorage web interface, click the Storage tab, then select

File Volumes.

2 Select the item to be shared in the tree list (the file volume root or a

subdirectory).

3 In the Windows Networking box, select Share As. 4 A default name appears in the Share Name field. You can change this

name to any name desired.

holding the shared object.

The HP NetStorage 6000 automatically generates a UNIX mount point at the root of the file volume when you create the volume. Mount points allow access to the system via the NFS protocol. By default, the mount point allows no access from any UNIX host when the volume is created. You must specifically grant access before UNIX host systems can mount the volume. Host access rights to resources via the NFS protocol are managed through the approve file.

The /etc/approve File

4-15

In traditional UNIX implementations, the exports file is used to restrict host access to the defined mount points. On the HP NetStorage 6000, this function is handled by the /etc/approve file. The administrator may edit this file:

n Directly from a text editor via an NFS (UNIX) mount or a Windows

share. The file is named approve, and is located in the /etc directory in the first file volume created on the system. The /etc direct ory is an administrative file directory. The files may be edited (with the correct permissions), but they cannot be deleted.

n From the HP NetStorage web interface, as explained in this section.

Entries in the approve file have four fields:

Managing Storage

Allowing Access to Data

Field Restrictions

class

This field specifies the class of object to protect. In all cases, the object is files.

specifier

This field specifies the resources on the NetStorage 6 00 0 server to protect. For example, /engineering, a pplies to all files and directories in the /engineering file system.

host pattern

This field has the name of a host or group of hosts that have access rights. Host names must be resolvable through the local /etc/hosts file, the NIS hosts file, or through DNS. Groups of hosts are specified in the / etc/hostgrps file. If the host pattern is the name of a group, then it must be preceded by the @ symbol. The wildcard character ( * ) may be used to specify all hosts. Note that the @general group is a pre-defined group that specifies all hosts.

rights

This field specifies the access limits to apply. The entry in this field can be:

access=rw Allow read and write access to the resources access=ro Allow read only access to the resources access=none Deny all access to the resource

The fields must be separated by one or more spaces or tabs. If a specifier contains space characters (such as a directory name that contains spaces), then the entire specifier must be enclosed in double quotes.

Whenever a host attempts to mount a volume, the approve file is searched to determine the appropriate access to grant the host. The file is searched sequentially from top to bottom. Wh en a match is found to the h ost patter n and the volume specifier, then the associated access rights are applied. All entries in the file after the matched entry are ignored. Therefore, it is important to order the entries in the file so that the more specific entries are listed first, and the more general entries are listed last.

4-16

Managing Storage

Allowing Access to Data

Here is a list of sample entries in the host access file:

#class specifier host pattern rights files /acct/usr it0 access=rw files /acct/usr @guest access=ro files /acct/etc it1 access=rw files /acct/etc it2 access=rw files /acct @general access=none

These five entries define the access to the /acct volume. In particular , the first two entries define access to the /acct/usr directory. Read only access is granted to the guest group (defined in the /etc/hostgrps file). The next two entries allow read/write access to the machines it1 and it2 to all files and directories in the /acct/etc directory. The last entry is a catch-all, indicating that all other hosts have no access to the /acct volume.

The following list demonstrates the use of wildcards and DNS domains:

#class specifier host pattern rights files /engineering *.eng.nas.hp.com access=rw files /engineering *.test.nas.hp.com access=ro files /engineering @general access=none files / @general access=none

The first three entries define the access allowed to the /engineering volume. The wildcard (*) character was used to s pecify all the machine s in a DNS domain. The last two lines in the examples are catch-alls, indi cating that all other hosts have no access to the /engineering volume or any other volume. These entries are optional sin ce access is always de nied if it is not specifically granted.

4-17

To view and edit the host access file using the NetStorage web interface:

1 Using the NetStorage web interface, click the Storage tab, then select

Host Access.

2 Modify the file as you would in any text editor. 3 Click Save Changes when you are done editing.

Note If there is no entry in the approve file to define access to a volume, then

access is denied to all hosts. The root user, mounting fr om a Trusted Host, always has full read/write access to all volumes, regardless of the access rights specified in the approve file.

Managing Storage

Allowing Access to Data

The /etc/hostgrps File

In most cases, you want to specify a gr oup of co mpu ters when iden tifying Host Access to the NetStorage 6000. In many of these situations, the wildcard character (*) serves this purpose. However, in some cases it is not sufficient. You can get around this problem by simply generating a Host Access entry for each computer, or you can define a group of host computers that may then be referenced by name (preceded by the @ symbol). A group of host computers may be defined by creating an entry in the /etc/hostgrps file. The file must be edited manually, using a text editor via the NFS protocol, or th e CIFS protocol (assuming that you have the proper rights).

Groups may be created by adding an en try into the /etc/hostgrps file. Each entry starts with the name of the group, followed by a sequence of host names to associate with the group. Every name is delimited by a space character. For example:

# Hostgrps file (group hosts under a name for access control) general * mygroup eng6284.stor.hp.com eng6a2c.stor.hp.com eng8106.stor.hp.co mygroup 10.58.159.245 hpcust6da6

Note The host names may appear as fully qualified domain names, IP

addresses, or host names as they appear in DNS or a hosts file. Entries for a group may span more than one line by entering the group name again at the beginning of the next line.

The host names must be resolvable through the hosts file, the NIS hosts file, or DNS.

Backup Overview

Backing Up and Restoring Files

Local and Remote Backups

Although the HP NetStorage 6000 provides RAID 5 hardware protection for your data, a backup strategy can prevent data loss in cases of inadvertent deletion or system disasters such as theft and fire. Using features built-in to your HP NetStorage 6000, a backup strategy can provide:

n Daily checkpoints for rapid recovery of individual files or directories,

plus. See “Creating Checkpoints” on page 5-9.

n Full backups on a weekly schedule for long-term storage and disaster

recovery. See “Creating and Executing Backup Jobs” on page 5-14.

T o perform backups, you need to attach ei ther an 8 18 or 1/9 HP SureStore DL T Autoloader to your HP NetStorage 6000 (see the installation poster for instructions). You can set up the tape device to perform two types of backups:

n A local backup: Use the backup application in the NetStorage web

interface plus an optional 818 or 1/9 HP SureStore DL T Autoloader . See “Performing a Local Backup” on page 5-5.

n A remote backup: Use one of several popular network remote backup

applications on a networked computer. See “Performing a Remote Backup” on page 5-6.

5-4

Backing Up and Restoring Files

Local and Remote Backups

Note You do not need to format tapes for a backup. However, before you load

tapes in the Autoloader, make sure they are not write-protected. The length of time required to perform a backup depends on the size of the

volume and the local area network (LAN). As a general rule:

n For a local backup, the Autoloader backs up 25 gigabytes per hour. n For a remote backup on a 10Base-T network, the Autoloader backs up

3 gigabytes per hour.

n For a remote backup on a 100Base -T network, the Autoloade r backs up

10 gigabytes per hour.

During a backup, the Autoloader’s control panel displa ys Writing and the green activity light flashes.

Performing a Local Backup

Use the backup application in the NetStorage web interface plus an optional 818 or 1/9 HP SureStore DLT Autoloader to perform a local backup. See the installation poster for directions on attaching the Autoloader to the HP NetStorage 6000 and see “Using the HP SureStore 818 or 1/9 DLT Autoloader” on page 5-1 for information on using the Autoloader.

5-5

Note You can only access Tape Status, T ape Backup, Tape Restore, and Tape

Settings in the Backup/Restore tab after you attach an Autoloader to

your HP NetStorage 6000 In a local backup session, a special checkpoint of yo ur data is first created

on disk, then the data is transferred to the locally attached Autoloader. The checkpoint uses only a small amount of disk space and the data transfer does not interfere with your LAN traffic.

To run a local backup:

1 From your workstation, o pen a web brows er and enter the IP addres s of

the HP NetStorage 6000.

2 Click the Backup/Restore tab, then select Tape Backup (see “Creating

and Executing Backup Jobs” on page 5-14 for more information).

The local backup feature provides simple scheduling capability and can be configured to back up individual files or combinations of volumes.

Performing a Local Restore

From a local backup tape, a restore operation can select an individual volume, directory , or file. Make sure you carefull y label and date your local backup tapes because a database of local backup operations is not maintained.

To run a local restore:

1 From your workstation, o pen a web br owser and ent er the IP addr ess of

the HP NetStorage 6000.

2 Select the Backup/Restore tab, then click Tape Restore (see

“Restoring Volumes” o n page 5-18 or “Restor ing Files and Directorie s” on page 5-20 for more information).

Performing a Remote Backup

Use third-party backup app lica tio ns on any computer on the network with a tape drive attached to perform a remote backup.

When you run a remote backup, data from the HP NetStorage 6000 transfers over the network to the remote server running the backup application, and then to the server-attached tape device. The remo te backup application cannot control the Autoloader connected to the HP NetStorage

6000.

Local and Remote Backups

If the backup application is running under NT, the restore operation recovers both the NT and UNIX security settings for each file. If the backup application is running under UNIX, the restored NT files revert to the default user security setting, while UNIX files retain their full security settings.

Disk Checkpoints

What Are Disk Checkpoints?

You can use the disk checkpoint feature to create a read-only virtual copy of your volume. This copy does not consume the equivalent disk space that an actual copy consumes. Because they are not real copies, checkpoints appear as a collection of directories in a virtual volume. Thi s volu me has the same name as the original volume but with a .chkpnt extension. Y ou can retrieve data from the checkpoint by browsing to the data you need and copying it to the desired location. You can also back up checkpoints to tape. For more information, see “Backing Up Checkpoints” on page 5-17.

You can create checkpoints manually (by checking Immediate) or have them created automatically at scheduled times by checking the appropriate boxes. The following table lists the checkpoints you can schedule and their deletion dates.

Checkpoint Creation Time Deletion

Immediate Now Delete manually Weekly Every Sunday at 1 am Automatically deletes

Nightly Every weekday at 1 am Automatically deletes

Daily Every weekday at 1 pm Automatically deletes

Every three hours Every weekday from 9 am

to 6 pm

in 14 days

in 7 days

in 3 days Automatically deletes

in 6 hours

5-7

You name immediate checkpoints. The system names scheduled checkpoints based on the creation date and time and their deletion date.

For example, if you created a three-hour scheduled checkpo int on January 19, 2000 at 9 am, the system names that checkpoint 20000119- 090001,6h. The date of this checkpoint is year 2000 , month 01, day 19, and the time you created it was 09 am, 00 min, 01 seconds. The checkpoint deletes in 6 hours.

If you do not want the system to delete the checkpoint on its deletion time, rename the checkpoint (see “Renaming or Deleting Checkpoints” on page 5-10). The name of the checkpoint is also th e name of its directory on the virtual volume.

Backing Up and Restoring Files

Disk Checkpoints

Note When checkpoints are created, they do not use much disk space. As you

make changes to the disk volume, checkpoints use increasing amounts of space. Checkpoints may be deleted automatically if the system begins to run out of disk space. To save disk space, delete old checkpoints periodically.

Checkpoints appear as a directory in the virtual volume. For example, if you have two checkpoints for volume X (one you created named ABC and a scheduled checkpoint named 20000119-090001,6h), you would find the following on the virtual volume:

/X.chkpnt/ABC (your checkpoint) /X.chkpnt/20000119-090001,6h (scheduled checkpoint)

Checkpoints have benefits and limitations.

Benefits Limitations

• Fast, accurate, and convenient file

archive.

• Quick and easy archive retrieval.

• Depends on the disk not failing.

• Uses increasing amounts of

storage over time.

• Uses minimal disk space initially.

Backing Up and Restoring Files

Restoring Volumes, Files, and Directories

Restoring Overview

T o restor e a volume, file , or directory, you need to know which tape(s) the volume, file, or directory resides on and which tape drive slots the tape is loaded in. (Remember to always label your tapes.) In restoring files and directories, you must also know the full path of the file/directory that you are retrieving, starting with the volume name.

Caution If you start a restore and have a backup scheduled to occur after your

restore finishes, the restore tape in the drive may be overwritten by the backup. To prevent this, remove the tape before the backup begins or write-protect the tape by sliding the write-protect switch until it clicks and an orange tab appears

The following information is retrieved from tapes that contain data:

n slot number being tested n job on the tape n position within the job n date and time you last wrote data to the tape

If you are testing the first tape of the backup set, the following additional information is retrieved:

n a list of volumes on the tape n type of backup on the tape (differential or full)

The first tape of a backup set must be selected to begin a restore.

Note If you changed the job since the backup, current information abou t the job

may not reflect what is on the tape.

Restoring Volumes

Before you begin a whole-volume restore on disk:

n You might want to clear the volumes of current data because you will

overwrite entire volumes.

n Make sure you restore from the full backup before restoring from a

differential backup.

Changing the Tape Protection Window

The tape protection window is a logical write-protection mechanism that the server enforces. The window requires that you set the correct date and time on the server. You accomplish physical tape-protection with the writeprotect tab on the tape cartridge. The tape protection window attempts to prevent accidental overwrite of tapes that are not physically writeprotected.

The Autoloader tests each tape’s protection setting before writing data to it. The default tape protection window is 7 days. For example, if a tape contains 5-day-old data and tap e protection is 7 days, the Aut oloader skips that tape and tests the next one. The Auto loader also s kips write-p rotected tapes and cleaning tapes.

To change the protection setting for tapes:

1 Using the NetStorage web interface, click the Backup/Restore tab, then

select Tape Settings.

Securing Data

About HP NetStorage 6000 Security

This section explains the details of security as it applies to the user data stored on the HP NetStorage 6000. The Ne tStorage 6000 utilizes mos t of the security features found on Microsoft Windows, as well as all of the security features found on UNIX platforms. It is not the intent of this section to review the specifics of those security arch itectures. Instead , th is section highlights the special features and differences that distinguish the security on the HP NetStorage 6000 from the security on traditional Windows or UNIX file servers.

Since the HP NetSto rage 6000 is designed to serve files o ver both NF S and CIFS/SMB protocols, it is necessary to establish a mapping of the security architectures from one platform to the other. “Mapping NT and UNIX Users” on page 8-12 explains how that mapping is accomplished.

Chapter 8

HP NetS torage 6000 Secu rity in a UNIX-only Environment

The NetStorage 6000 utilizes an internal file system that is native to UNIX environments. As such, it has UNIX security mechanisms bu ilt-in that are leveraged when serving files over the NFS protocol. All resources stored on the file system contain the security metadata commonly found in UNIX systems.

The NetStorage 6000 does not support the co ncept of the /etc/exports file for managing mount points. Instead, the ser ver automatically creates a single mount point at the root of all volumes created on the system. Since the server is specifically designed to share files, the exporting of mount points has been automated.

The root directory of the mount points on the NetStorage 6000 is given special permissions to facilitate appropriate access to users. The owner and group of this directory are root (UID = 0, GID = 0), and the permissions are read, write, and execute to owner, group and other (rwxrwxrwx). One

8-1

consequence of this setting is that all users can delete any file in the root of the mount point. Therefore, administrators are encour aged to avoid storing files in the root of the mount point.

The group assignment to files created in a file volume on UNIX can be performed in a variety of wa ys. O n the Ne tStorage 6000, when a new file is created, the group assignment is inherited from the directory where the file is created. For example, if the group owner for directory /acct/usr is accountants (GID = 501), then all files created in that directory will be assigned a group owner of accountants (GID = 501).

Trusted Hosts

All UNIX clients that mount to file systems on the NetStorage 6000 use the UID and GID of their account when accessing files. A special case is the root user (UID = 0). In UNIX, the root user is a Super User , with full access to all files and directories in the file system. Due to the extensive rights provided to the root user, and the extensive damage that can be done by a malicious root user, the NetStorage 6000 does not trust them by default. Clients that attach with root privilege are given access as user nobody (UID = 60001), with no special rights or privileges.

The administrator can override this default behavior by declaring a particular client to be a Trusted Host. A root user mounting a NetStorage 6000 file system from a cl ient t hat is a Trusted Host is given root privileg e (UID = 0) to the file system. This feature allows administration of the file system by a root user, while at the same time, protecting the file system from other root users that should not have privileged access to the NetStorage 6000 file systems.

Securing Data

HP NetStorage 6000 Security in a UNIX-only Environment

The administrator may declare Trusted Hosts using the web based administration tool, or the telnet administration tool of the NetStorage

6000.

8-2

Securing Data

HP NetStorage 6000 Security in a UNIX-only Environment

The /etc Directory

It is necessary to maintain a number of system files on the NetSto rage 6000 in an accessible place for administrative purposes. Some of the more common files found in this directory are:

Filename Description

hosts Resolves host names hostgrps Defines groups of host computers approve Restricts host access users.map Maps Windows user accounts to UNIX user accounts group.map Maps Windows group accounts to UNIX group accounts

All of these files are stored in the /etc directory on the first volume created on the system. The files in the /etc directory are for system management purposes and cannot b e del et ed. I f t he v olume that stores the /etc directory is ever deleted, then the system moves the contents of this directory to another available volume.

Most of the files in the /etc directory may be edited through the web based user interface, or the telnet interface of the HP NetStorage 6000. In some cases, it is necessary to edit these files directly using a text editor. By default, all files in the /etc directory are owned by the root user , and may only be edited by the root user. Therefore, the only way to edit these files directly (using a text editor) is to mount the file system as the root user from a Trusted Host. See “Trusted Hosts” on page 8-2.

8-3

The /etc/approve File

Since the NetStorage 6000 does not support the /etc/exports file, support has been added for a file named /etc/approve. This file can be used to restrict NFS access to particular clients on the network.

In order to restrict individual clients and groups of clients to specific resources on the NetStorage server, the /etc/approve file must be edited. The file may be edited manually, or from the web based user interface, under the Host Access section of the Storage tab. Entries in the /etc/approve file have four fields. These fields are defined as follows:

Securing Data

the object is files.

This field has the name of a host or group of hosts that have access rights. Host names must be resolvable through the local /etc/hosts file, the NIS hosts file, or through DNS. Groups of hosts are specified in the /etc/hostgrps file. If the host pattern is the name of a group, then it must be preceded by the @ symbol. The wildcard character ( * ) may be used to specify all hosts.

field can be one of the following:

• access=rw allows read and write access to the resources

• access=ro allows read only access to the resources

• access=none denies all access to the resource

Additional information about the format of this file, as well as detailed examples may be found in “Edit Host Access” on page 4-15.

The file is searched sequentially for a match. Once an entry is found that matches the host and the resource to restrict, all other entries are ignored.

HP NetStorage 6000 Security in an NT-only Environment

On Microsoft Wind ows, the protocol used to transfer files over the network between a server and a client is known as Server Message Block (SMB), or Common Internet File System (CIFS). Many variations of the protocol exist which reflect the myriad flavors of W indows on the Market; Wi ndows 95/98, Windows NT, and Windows 2000.

Given all these variations, there are two distinct mechanisms used in CIFS to provide security for resou rces. They are known as Share-Lev el Security and User-Level Security. The HP NetStorage 6000 supports both of these security modes. The next two sections briefly explain the architecture of these security modes, and highlight any special considerations that should be noted for the HP NetStorage 6000.

8-4

Securing Data

HP NetStorage 6000 Security in an NT-only Environment

Share-Level Security

Share-level security is the simplest CIFS security mode to use, but offers the least security. In this mode, each share is protected by a password. When the server administrator defines a new shar e, a password is specified to protect the share from unauthorized access. When a user first accesses the share they are prompted for the password. Once the passwor d is entered and verified, then the user has full access to all files on the share. ShareLevel security is the default security mode for Windows for Workgroups and Windows 95.

Share-Level security may be implemented to allow both Read/Write access, as well as Read Only access to shares. Each share may be protected by a Read/Write password and a Read Only pass word. The access allowed on the share (Read/W rite or Read Only) is dictated by the password entered by the user.

By default, the NetStorage 6000 accepts encrypted passwords for verification. In these cases, Windows NT (also known as NT LM 0.12) password encryption is used. The NetStorage 6000 also accepts plaintext passwords from older clients, for backward compatibility.

Since the native file system on the NetStorage 6000 is UNIX based, all files must have a UID and GID associated with them. However, since ShareLevel security does not s upport the concept of users or groups, a single UI D and GID is assigned to each share, such that all files created in the share from Windows clients are assigned the UID and GID of the share. When shares are managed through the web based administration tool, shares are automatically assigned a UID and GID of zero (UID = 0, GID = 0). For administrators with special needs, the default UID and GID of zero may b e changed for a given share. The telnet interface of the NetStorage 6000 allows the user to specify the UID and the GID to be used for a particular share. In this case, ALL directories and files created in the share are assigned the UID and GID specified by the administrator.

8-5

Since Share-Level security allows the user full access to all files regardless of the UNIX permission settings, it is up to the administrator to ensure that the Windows shares are created in such places so as not to expo se sensitive system files, or the resources of other UNIX users.
