HP StorageWorks P9000 Command View Advanced Edition Suite Software 7.0 Mainframe Agent Installation and Configuration Guide (TB581-96014, November 2010)

• When a volume is concealed and disk configuration is rescanned, an error message indicating
that "the device has been ejected" 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 may 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 disks are displayed when
volumes are concealed for some of the disks in the disk group. Perform volume conceal for copy
groups of Foreign disks and Online disks as well.
• If this command is executed with the -detach option specified, take the physical volume offline
(closed) from all applications. 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 is updated properly.
Note that, if a volume with the same updated signature already exists, the command might update
to a different disk signature, set by Windows. If this happens, execute the -sigset option, and
specify the copy group to the physical volume for which you want to update the disk signature.
Then, update the disk signature to a different value, making sure to avoid signature overlap.
• 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 is used to conceals the secondary volumes of all copy groups, and
performs a drive rescan:
PROMPT> drmdevctl -detach
