lsdrivelba

Use the lsdrivelba command to map array MDisk logical block address (LBA) to a set of drives.

Syntax

Parameters

-delim delimiter: (Optional) Specify a delimiter to separate data in the output.
-nohdr: (Optional) Suppress the headings in the output.

-mdisklba lba: (Required) The logical block address (LBA) on the MDisk. The LBA must be specified in hex, with a 0x prefix.
-mdiskmdisk_id | mdisk_name: (Required) The ID or name of the MDisk.

Description

This command maps the array MDisk LBA to a set of drives.

Note: This command applies to SAS drives.

The system provides volumes that have LBAs for 512-byte block sizes, but back-end disks that have a block size of either 512 or 4096 bytes can also be used. Drives are listed in their physical size.

Use the lsdrive command to display the drive block size, and use the lsdrive or lsarray command to list each object (the drive and the MDisk).

This table describes possible outputs.

Table 1. lsdrivelba output
serial-attached SCSI \| \| \| (SAS) Attribute	Value
drive_id	The ID of drive; blank if no configured array member exists (for example, in a degraded array).
type	The type of information on the disk: `parity`, in which LBA range contains `parity` (RAID levels 5 and 6 only) `qparity`, in which LBA range contains `qparity` (RAID level 6 only) `data`, in which LBA range contains data
drive_lba	The LBA on the drive.
drive_start	The start of range of LBAs (strip) on the drive.
drive_end	The end of range of LBAs (strip) on the drive.
mdisk_start	The start of range of LBAs (strip) on the array MDisk.
mdisk_end	The end of range of LBAs (strip) on the array MDisk.
