Use the lscontrollerdependentvdisks command to list the volumes that depend on the specified controller.


lscontrollerdependentvdisks [ -nohdr ] [ -delimdelimiter ] { controller_id_list | controller_name_list }


(Optional) By default, headings are displayed for each column of data in a concise style view, and for each item of data in a detailed style view. The -nohdr parameter suppresses the display of these headings.
Note: If there is no data to be displayed, headings are not displayed.
-delim delimiter
(Optional) By default in a concise view, all columns of data are space-separated. The width of each column is set to the maximum width of each item of data. In a detailed view, each item of data has its own row, and if the headers are displayed, the data is separated from the header by a space. The -delim parameter overrides this behavior. Valid input for the -delim parameter is a 1-byte character. If you enter -delim : on the command line, the colon character (:) separates all items of data in a concise view; for example, the spacing of columns does not occur. In a detailed view, the data is separated from its header by the specified delimiter.
controller_id_list | controller_name_list
Specifies one or more controller IDs, controller names, or both. Separate multiple controllers using the colon character (:).


The lscontrollerdependentvdisks command lists the volumes that depend on the status of the specified controllers. If a controller goes offline, the dependent volumes also go offline. Before you take a controller offline for maintenance, you can use the command to ensure that you do not lose access to any volumes.

If you have multiple controllers that are configured as a single subsystem, you must specify all of the controllers in the subsystem. When you do this you must specify a single command invocation.

The lscontrollerdependentvdisks command also checks for quorum disks on the specified controller list. If any quorum disks are on the specified controller list, the command returns an error. All quorum disks must be moved before you perform any maintenance. After you move quorum disks, reissue the command to list the dependent volumes.
Note: The command lists the volumes that depend on the controllers at the time the command is run; subsequent changes to your system require rerunning the command.

An invocation example

lscontrollerdependentvdisks controller0

The concise resulting output:

vdisk_id vdisk_name
0 vdisk0
1 vdisk1
2 vdisk2
