HP StorageWorks P9000 Replication Manager Software 7.1 CLI Reference Guide (TB584-96021, May 2011)

• When a volume is concealed and the disk configuration is rescanned, an error message indicating
that a device has been removed is recorded in the Windows event log. HP recommends that you
delete the event log regularly.
• If this command is executed for a dynamic disk copy group, with the -detach option specified,
Missing disks and Failed volumes might be displayed to the Windows disk manager and Veritas
Enterprise Administrator. This happens because another dynamic disk on the server records the
existence of a volume concealed by the drmdevctl command. This can be avoided by performing
the following:
For an environment with Veritas Volume Manager for Windows:
In an environment with Veritas Volume Manager for Windows, Missing is displayed for disks when
volumes have been concealed for some of the disks in the disk group. Conceal volumes also for
copy groups with disks displayed as Foreign or Online.
• If this command is executed with the -detach option specified, take the physical volume offline
from all applications (close the volume). If you leave the volume online, the physical volume will
be forcefully concealed from the server even if applications are being used, which might result in
unexpected application problems.
• If the local volume is not mapped to the physical volume because, for example, the copy group
is concealed, the following limitations apply:
• When the command is executed with the -sigview option specified, the current disk signature
cannot be viewed. The output result of the command is displayed as --------.
• When the command is executed with the -sigset option specified, the disk signature cannot
be updated.
To display and update the current disk signature, the copy group must be displayed and the local
volume must be mapped to the physical volume.
• If the disk signature is updated with the -sigset option specified, execute the command again
with the -sigview option specified and make sure that the disk signature has been updated
properly.
Note that if the updated disk signature already exists on another volume, the disk signature might
be updated to a different disk signature set by Windows. If this happens, execute the command
by specifying both the -sigset option and the copy group of the physical volume whose disk
signature you want to update. Update the disk signature to a different value, making sure to avoid
duplicating another disk signature.
• If an attempt to update the disk signature is made with the -sigset option specified when the
disk signature format is different from the disk partition style, the KAVX5170-E error message is
displayed and the command will terminate with an error.
• If this command is executed with both the -sigview option and backup-ID specified, and the
disk signature format registered in the backup catalog is different from the current disk partition
style, the KAVX5171-E error message is displayed and the command will terminate with an error.
Return Values
0: Normal termination
Any value other than 0: Termination with an error
Examples
• In this example, the command conceals the secondary volumes of all copy groups, and performs
a drive rescan:
