Use the lsvdiskextent command to list
the MDisk extents 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 there is no data 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 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.
- vdisk_name | vdisk_id
- (Required) Specifies one or more volume IDs or names.
Description
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 given
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.
An invocation example
lsvdiskextent -delim : vdisk0
The resulting output
