Description
This command conceals or reveals physical volumes of storage system devices connected to the server.
By concealing physical volumes from the server and controlling access, you can prevent errors caused
by user operations.
In addition, you can conceal physical volumes to obtain backups in Veritas Volume Manager for
Windows environments, or to obtain backups by using XP Snapshot. You can then store these backups
in multiple generations of secondary volumes and back up each generation to a tape device via the
backup server.
Because you can target all copy groups managed by Application Agent, you can perform an initial
setup of a volume-concealed environment for backup servers. By specifying a backup ID and copy
group, you can also execute this command after narrowing the list of potential targets.
You can also use this after starting operations, to conceal or reveal physical volumes of storage system
devices connected to the server.
When the restoration command is terminated by an error on the file server or database server, the
disk signature of the copy group can be displayed and updated on the backup server. This helps
recovery from the error that occurred during the restoration.
Note that you must set DEVICE_DETACH=ENABLE in the RAID Manager-linkage definition file
(DEFAULT.dat) when specifying the -detach, -attach, or -rescan options.
Arguments
backup-ID
Specify the backup ID of a backup catalog. When a backup ID is specified, the target physical volumes
are the secondary volumes of the copy groups registered in the backup catalog.
-copy_group copy-group-name
Specify a valid copy group name. The target physical volumes are the secondary volumes of the copy
group specified.
