Use the lsvdisklba command to list the volume and logical block
address (LBA) for the specified storage pool LBA.
Syntax
lsvdisklba -mdisklbamdisklba [ -delimdelimiter ] [ -nohdr ] -mdisk { mdisk_id | mdisk_name }
Parameters
- -mdisklbamdisklba
- (Required) Specifies the 64-bit hexadecimal LBA on the MDisk. The LBA must be specified in
hex, with a 0x prefix.
- -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.
- -mdiskmdisk_id | mdisk_name
- (Required) Specifies the MDisk name or ID.
Description
The lsvdisklba command returns the LBA of the volume that is associated
with the MDisk LBA.
If applicable, the command also lists the range of LBAs on both the volume and MDisk that are
mapped in the same extent, or for thin-provisioned disks, in the same grain.
Note: If lsvdisklba is run during a
software upgrade, the command fails and an error message is displayed.
The vdisk_lba field provides the corresponding LBA on the virtual
capacity for the input LBA. For compressed volume copies, it is blank and the system provides
the ranges of virtual LBAs that are compressed into the input LBA.
This table provides command output that depends on several variables.
