Use the lsvdiskextent command to list the MDisk extents that are
provided for the specified volumes.
Syntax
lsvdiskextent [ -copy copy_id ] [ -nohdr ] [ -delim delimiter ] { vdisk_name | vdisk_id }
Parameters
- -copycopy_id
- (Optional) Displays a list of MDisks that are members of the specified volume copy.
- -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.
- -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.
- vdisk_name | vdisk_id
- (Required) Specifies one or more volume IDs or names.
Description
Note: You cannot specify this command for a thin-provisioned or
compressed volume or a volume copy that is in a data reduction storage pool.
The lsvdiskextent command displays a list of
MDisk IDs and the number of extents that each MDisk provides to the specified volumes.
Each volume is constructed from one or more MDisks. To determine the relationship between
a volume and its MDisks, issue the following command:
lsvdiskmember vdisk_name | vdisk_id
where
vdisk_name | vdisk_id is the name or ID of the volume. This command
displays a list of MDisk IDs that make up the volume.
To determine the number of extents
that are provided by each MDisk, issue the following command:
lsvdiskextent vdisk_name | vdisk_id
where
vdisk_name | vdisk_id is the name or ID of the volume. This command
displays a table of MDisk IDs and the corresponding number of extents that each MDisk provides
as storage for the specified volume.
To determine the relationship between MDisks and
volumes, issue the following command for each MDisk:
lsmdiskmember mdisk_name | mdisk_id
where
mdisk_name | mdisk_id is the name or ID of the MDisk. This command displays
a list of IDs that corresponds to the volumes that are using this MDisk.
To determine the relationship between MDisks and volumes, and the number of extents that are used
by each volume, you must use the command-line interface. For each MDisk, issue the following
command:
lsmdiskextent mdisk_name | mdisk_id
where
mdisk_name | mdisk_id is the name or ID of the MDisk. This command displays
a table of volume IDs and the corresponding number of extents that are used by each volume.
Note: If the MDisk specified is in a data reduction
pool, the output includes all thin-provisioned and compressed volumes in the pool without
displaying the number of extents in each.
