Veritas NetBackup™ Administrator's Guide, Volume I

Volume properties

Table: Volume properties describes the properties for volumes in NetBackup. The properties depend on whether you add, change, or move volumes.

The properties are arranged alphabetically.

Table: Volume properties

Property

Description

Operation

Device host

The name of the NetBackup media server to which the robot is attached.

Add, move

Expiration date

The following does not apply to cleaning tapes.

The date after which the volume is too old to be reliable.

When the expiration date has passed, NetBackup reads data on the volume but does not mount and write to the volume. You should exchange it for a new volume.

When you add a new volume, NetBackup does not set an expiration date.

The expiration date is not the same as the retention period for the backup data on the volume. You specify data retention periods in the backup policies.

Change

First media ID

This property appears only if the number of volumes is more than one.

The ID of the first volume in the range of volumes. Media IDs can be from 1 to 6 characters in length. Valid only when you add a range of volumes.

Use the same pattern that you chose in the Media ID naming style box. NetBackup uses the pattern to name the remaining volumes by incrementing the digits.

NetBackup allows specific characters in names.

Add

First slot number

The number of the first slot in the robot in which the range of volumes resides. If you add or move more than one media, NetBackup assigns the remainder of the slot numbers sequentially.

Note:

You cannot enter slot information for volumes in an API robot. The robot vendor tracks the slot locations for API robot types.

Add, move

Maximum cleanings

The maximum number of times NetBackup should mount the volume or use the cleaning tape.

When a volume reaches the mount limit, the volume can be read, but not written. Zero (0) means that the cleaning tape is not used. If you enter a value larger than 99999, NetBackup may display it as 0, although it uses the actual value. For example, the output of the vmrule command displays 0 for values larger than 99999.

To determine the maximum mount limit to use, consult the vendor documentation for information on the expected life of the volume.

Add

Maximum mounts

The following topic does not apply to cleaning tapes.

The Maximum mounts property specifies the number of times that the selected volumes can be mounted.

When the limit is reached, NetBackup reads data on the volume but does not mount and write to the volume.

A value of zero (the default) is the same as Unlimited.

To help determine the maximum mount limit, consult the vendor documentation for information on the expected life of the volume.

Add, change

Media description

A description of the media, up to 25 character maximum.

NetBackup allows specific characters in names.

Add, change

Media ID

This property appears only if the number of volumes is one.

The ID for the new volume. Media IDs can be from 1 to 6 characters in length.

Media IDs for an API robot must match the barcode on the media (for API robots, NetBackup supports barcodes from 1 to 6 characters). Therefore, obtain a list of the barcodes before you add the volumes. Obtain this information through a robotic inventory or from the robot vendor's software.

NetBackup allows specific characters in names.

Add, change

Media ID naming style

The style to use to name the range of volumes. Media IDs can be from 1 to 6 characters in length. Using the pattern, NetBackup names the remaining volumes by incrementing the digits.

NetBackup media IDs for an API robot must match the barcode on the media. For API robots, NetBackup supports barcodes from 1 to 6 characters. Therefore, obtain a list of the barcodes before you add the volumes. Obtain this information through a robotic inventory or from the robot vendor's software.

NetBackup allows specific characters in names.

Add

Media type

The media type for the volume to add.

Select the type from the drop-down list.

Add

Number of volumes

The number of volumes to add. For a robotic library, enough slots must exist for the volumes.

Add

Robot

The robotic library to add or move the volumes to.

To add volumes for a different robot, select a robot from the drop-down list. The list shows robots on the selected host that can contain volumes of the selected media type.

Add, move

Volume group

If you specified a robot, select from a volume group already configured for that robot. Alternatively, enter the name for a volume group; if it does not exist, NetBackup creates it and adds the volume to it.

If you do not specify a volume group (you leave the volume group blank), the following occurs:

  • Standalone volumes are not assigned to a volume group.

  • NetBackup generates a name for robotic volumes by using the robot number and type. For example, if the robot is a TL8 and has a robot number of 50, the group name is 000_00050_TL8.

See About rules for moving volumes between groups.

Add, move

Volume is in a robotic library

When you add a volume:

  • If the volume is in a robot, select Volume is in a robotic library.

  • If the volume is a standalone volume, do not select Volume is in a robotic library.

When you move a volume:

  • To inject a volume into a robotic library, select Volume is in a robotic library. Then, select a robot and the slot number (First slot number) for the volume.

  • To eject a volume from a robot, clear Volume is in a robotic library.

Add, move

Volume pool

The pool to which the volume or volumes should be assigned.

Select a volume pool you created or one of the following standard NetBackup pools:

  • None.

  • NetBackup is the default pool name for NetBackup.

  • DataStore is the default pool name for DataStore.

  • CatalogBackup is the default pool name used for NetBackup catalog backups of policy type NBU-Catalog.

When the images on a volume expire, NetBackup returns it to the scratch volume pool if it was allocated from the scratch pool.

Add, change

Volumes to move

The Volumes to move section of the dialog box shows the media IDs of the volumes that you selected to move.

Move
