Use the lscontrollerdependentvdisks command
to list the volumes that are dependent on the specified controller.
Syntax
lscontrollerdependentvdisks [ -nohdr ] [ -delim delimiter ] { controller_id_list | controller_name_list }
Parameters
- -nohdr
- (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 possible 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 one-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 (:).
Description
The lscontrollerdependentvdisks command lists
the volumes that are dependent on the status of the specified controllers.
If a controller goes offline, the dependent volumes also go offline. Before taking 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 configured as a single subsystem,
you must specify all of the controllers in the subsystem, using 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 performing
any maintenance.
After moving quorum disks, reissue the command
to list the dependent volumes.Note: The command lists the volumes
that are dependent 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
