Use the lsmdiskmember command to display a list of volumes that use
extents on the specified MDisk. That is, the volumes use extents on the managed disk that are
specified by the MDisk ID.
Syntax
lsmdiskmember [ -nohdr ] [ -delim delimiter ] { mdisk_id | mdisk_name }
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 no data exists 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.
- mdisk_id | mdisk_name
- (Required) Specifies the ID or name of the MDisk for which you want a list of volumes that
use extents of that MDisk.
Description
This command displays a list of volumes that use extents on the managed disk that are specified
by the ID. The list displays members of the respective object and is independent of the state of
the individual members. That is, if they are in offline state, they are still displayed.
- A volume in a data reduction storage pool cannot display how many members are on an MDisk
that is in a data reduction pool.
- If the MDisk specified is in a data reduction pool, output includes all thin-provisioned
and compressed volumes in the pool.
- Fully allocated VDisks in data reduction pools are displayed correctly.
Every volume is constructed from one or more MDisks. To determine the relationship between
volume copies and MDisks, issue the following command:
lsvdiskmember vdisk_id | vdisk_name
where
vdisk_id | vdisk_name is the name or ID of the volume copy. This
action displays a list of IDs that correspond to the MDisks that make up the
volume
copy.
To determine the relationship between
volume copies and MDisks and
the number of extents that are provided by each MDisk, you must use the command-line interface.
For each
volume copy, issue the following command:
lsvdiskextent vdisk_id | vdisk_name
where
vdisk_id | vdisk_name is the name or ID of the volume copy. This
command displays a table of MDisk IDs and the corresponding number of extents that each MDisk
provides as storage for the volume copy.
To determine the relationship
between MDisks and
volume copies, issue the following command:
lsmdiskmember mdisk_id | mdisk_name
where
mdisk_id | mdisk_name is the name or ID of the MDisk. This command
displays a list of IDs that correspond to the volume copies that are using this MDisk.
To
determine the relationship between MDisks and volume copies and the number of extents that are
used by each volume copy, you must use the command-line interface. For each MDisk
mdisk_id | mdisk_name, issue the following command:
lsmdiskextent mdisk_id | mdisk_name
where
mdisk_id | mdisk_name is the name or ID of the MDisk. This command
displays a table of volume copy IDs and the corresponding number of extents that are being used
by each volume copy.
