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

-detach
Conceals the physical volumes of the storage system from the server, and instructs the OS of the server
to perform a disk rescan.
-attach
Reveals (publishes) physical volumes of the storage system that are concealed from the server, and
instructs the OS of the server to perform a disk rescan.
-noscan
Specify this to stop the OS from being instructed to perform a disk rescan, after a volume is concealed
or revealed. Note that if even one volume is concealed or revealed, an OS disk rescan instruction
(-rescan) is necessary. Since an inconsistency may develop between the OS and the actual disk
configuration if no disk rescan instruction is performed, operation is not guaranteed if operations
other then drmdevctl -detach or drmdevctl -attach are executed.
This option must be specified when either the -detach or -attach option is specified.
-rescan
Instructs the OS to perform a disk rescan. A disk rescan is required after a volume is concealed or
revealed. The time required to process a disk rescan depends on the hardware configuration, and
the number of disks connected in particular.
This option cannot be specified with other options.
-sigview
Displays the disk signature of the physical volume. Use this option to restore the operation when the
KAVX5137-E message is output and the restoration command terminates with an error.
• When the backup ID is specified to the -sigview option: The disk signature recorded when the
backup was made is displayed. This helps to compare disk signature values of the backup and
the current.
• When both the -sigview option and -copy_group copy-group-name are specified at the same
time, or neither the backup ID for the -sigview option nor the -copy_group copy-group-name
is specified, only the current disk signature is displayed. The disk signature registered at backup
is displayed as --------.
The following table shows the items displayed when the -sigview option is specified:
Table 32 Items displayed by the drmdevctl -sigview command
