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
