nvme-lnvm-diag-bbtbl — Diagnose the bad block table

Synopsis

nvme lnvm-diag-bbtbl [--namespace-id=<NUM> | -n <NUM>]
                        [--channel-id=<CHID> | -c <CHID>]
                        [--lun-id=<LUNID> | -l <LUNID>]
                        [--raw-binary | -b]

Description

Retrieve the bad block table for a given channel and lun.

The statistics will be shown in the default case, and the actual output bad block information can be retrieved when --raw-binary is passed.

The raw binary output follows this format:

Channel 0, LUN0 (Dual plane flash)

Byte 0 → Plane 0, Block 0 Byte 1 → Plane 1, Block 0 Byte 2 → Plane 0, Block 1 ...

Options

--namespace-id=<NUM>, -n <NUM>
Namespace id to use
--channel-id=<NUM>, -c
Channel id
--lun-id=<NUM>, -l
LUN id
--raw-binary, -b
Returns the bad block table in binary form without statistics.

Examples

· Retrieve bad block table statistics for physical device nvme0, channel 0, and lun 0:

# nvme lnvm-diag-bbtbl /dev/nvme0 -c 0 -n 0

· Display the bad block table in raw form without statistics for same query:

# nvme lnvm-diag-bbtbl /dev/nvme0 -c 0 -n 0 -b | hexdump
