Use the lsdependentvdisks command to view which volumes go offline if you remove a specific
piece of hardware from the system.
Syntax
lsdependentvdisks [ -nohdr ] [ -delim delimiter ] { -node { node_name | node_id } | -controller { controller_name_list | controller_id_list } | -mdisk { mdisk_name_list | mdisk_id_list } | -drive drive_id_list | -enclosure enclosure_id [ -sem sem_id ] [ -canister canister_id ] }
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.
- -delimdelimiter
- (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.
- -nodenode_name | node_id
- (Optional) Specifies the node for which volume dependency
is required.
- -controllercontroller_name_list | controller_id_list
- (Optional) Specifies the controllers for which volume dependency
is required.
- -mdiskmkdisk_name_list | mkdisk_id_list
- (Optional) Specifies the MDisks for which volume dependency
is required.
- -drive
- (Optional) Specifies the drives for which volume dependency
is required. There is a maximum of 128 entries.
- -enclosureenclosure_id
- (Optional) Specifies the enclosure for which volume dependency
is required. You can remove a control enclosure without affecting
your other data.
- -semsem_id
- (Optional) Specifies the volumes that depend on secondary expander module availability. The
possible values are 1 and 2.
Note: If you do not specify
-sem this command shows the volumes that depend on the enclosure.
- -canistercanister_id
- (Optional) Specifies an enclosure canister. The possible values
are 1 and 2.
Description
Use
this command to view which volumes go offline if you remove a specific
piece of hardware from the system. Use this command to determine which
volumes are affected before undergoing maintenance.
An invocation example
lsdependentvdisks -delim : -drive 0:1
The
resulting output:
vdisk_id:vdisk_name
4:vdisk4
5:vdisk5
Note: This means that if drives 0 and 1 are
removed, then volume vdisk4 and volume vdisk5 go
offline.
