The lsmdisklba command lists the MDisk and logical block address (LBA) for the specified VDisk LBA.
Syntax

Parameters
- -vdisklba vdisklba
- (Required) Specifies the 64–bit hexadecimal logical block address (LBA) on the VDisk.
- -copy id
- (Optional) Specifies the VDisk copy ID to list the MDisk and LBA for. If this parameter is not specified, the command lists MDisks and LBAs for all VDisk copies.
- -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.
- vdisk_id | vdisk_name
- (Required) Specifies the VDisk name or ID.
Description
The lsmdisklba command returns the logical block address (LBA) of the MDisk that is associated with the VDisk LBA. For mirrored VDisks, the command lists the MDisk LBA for both the primary and the copy.
If applicable, the command also lists the range of LBAs on both the VDisk and MDisk that are mapped in the same extent, or for space-efficient disks, in the same grain. If a space-efficient VDisk is offline and the specified LBA is not allocated, the command displays the VDisk LBA range only.
Table 1 summarizes
the data that can be returned with this command.
| Field | Fully allocated, single copy VDisk | LBA not allocated on space-efficient VDisk | Mirrored VDisk with one normal copy and one offline space-efficient copy | |
|---|---|---|---|---|
| Normal copy | Space-efficient copy | |||
| copy_id | yes | yes | yes | yes |
| mdisk_id | yes | no | yes | no |
| mdisk_name | yes | no | yes | no |
| type | allocated | unallocated | allocated | offline |
| mdisk_lba | yes | no | yes | no |
| mdisk_start | yes | no | yes | no |
| mdisk_end | yes | no | yes | no |
| vdisk_start | yes | yes | yes | yes |
| vdisk_end | yes | yes | yes | yes |
