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

lsmdiskmember [ -nohdr ] [ -delimdelimiter ] { 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 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.
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.

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 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.
