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
