NAME¶
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
