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 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.
- -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.
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.
Table 1 provides command
output that depends on several variables.
