lsmdiskmember
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
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/vdisk_id | mdisk_name/vdisk_name
- (Required) Specifies the ID or name of the MDisk or volume copy 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.
- standard-provisioned volume copies 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
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
To determine the relationship between MDisks and volume copies, issue the following command:
lsmdiskmember mdisk_id | mdisk_name
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
An invocation example
lsmdiskmember -delim : 1
The resulting output:
id:copy_id
0:0
1:0
2:0
3:0
