lsmdiskextent

The lsmdiskextent command displays the extent allocation between managed disks and virtual disks. The output lists a VDisk ID, VDisk copy ID, and the number of extents.

Syntax


>>- svcinfo -- -- lsmdiskextent -- --+----------+-- ------------>
                                     '- -nohdr -'      

>--+-----------------------+-- --+- mdisk_name -+--------------><
   '- -delim -- delimiter -'     '- mdisk_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.
-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_name | mdisk_id: (Required) Specifies the specific object ID or name of the given type.

Description

The command displays a list, in which each entry contains a VDisk ID, VDisk copy ID, and the number of extents. These VDisk copies are using extents on the specified MDisk. The number of extents being used on each MDisk is also shown.

Every VDisk copy is constructed from one or more MDisks. At times, you might have to determine the relationship between the two objects. The following procedure allows you to determine the relationships.

To determine the relationship between VDisk copies and MDisks, issue the following command for each VDisk copy:

svcinfo lsvdiskmember vdisk_name | vdisk_id

where vdisk_name | vdisk_id is the name or ID of the VDisk copy. This displays a list of IDs that correspond to the MDisks that make up the VDisk copy.

To determine the relationship between VDisk copies and MDisks and the number of extents that are provided by each MDisk, you must use the command-line interface. For each VDisk copy, issue the following command:

svcinfo lsvdiskextent vdisk_name | vdisk_id

where vdisk_name | vdisk_id is the name or ID of the VDisk copy. This displays a table of MDisk IDs and the corresponding number of extents that each MDisk is providing as storage for the given VDisk copy.

To determine the relationship between MDisks and VDisk copies, issue the following command for each MDisk:

svcinfo lsmdiskmember mdisk_name | mdisk_id

where mdisk_name | mdisk_id is the name or ID of the MDisk. This displays a list of IDs that correspond to the VDisk copies that are using this MDisk.

To determine the relationship between MDisks and VDisk copies and the number of extents that are used by each VDisk copy, you must use the command-line interface. For each MDisk, issue the following command:

svcinfo lsmdiskextent mdisk_name | mdisk_id

where mdisk_name | mdisk_id is the name or ID of the MDisk. This command displays a table of VDisk copy IDs and the corresponding number of extents that are being used by each VDisk copy.

An invocation example

svcinfo lsmdiskextent -delim : mdisk0

The resulting output

id:number_of_extents:copy_id
1:1:1
