Diagnose the bad block table
Usage
nvme lnvm-diag-bbtbl
[{--namespace-id=<NUM> | -n
<NUM>}]
[{--channel-id=<CHID> | -c
<CHID>}]
[{--lun-id=<LUNID> | -l
<LUNID>}]
[{--raw-binary | -b}]
Overview
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
