NAME

6       nvme-lnvm-diag-bbtbl - Diagnose the bad block table
7

SYNOPSIS

9       nvme lnvm-diag-bbtbl [--namespace-id=<NUM> | -n <NUM>]
10                               [--channel-id=<CHID> | -c <CHID>]
11                               [--lun-id=<LUNID> | -l <LUNID>]
12                               [--raw-binary | -b]
13

DESCRIPTION

15       Retrieve the bad block table for a given channel and lun.
16
17       The statistics will be shown in the default case, and the actual output
18       bad block information can be retrieved when --raw-binary is passed.
19
20       The raw binary output follows this format:
21
22       Channel 0, LUN0 (Dual plane flash)
23
24       Byte 0 → Plane 0, Block 0 Byte 1 → Plane 1, Block 0 Byte 2 → Plane 0,
25       Block 1 ...
26

OPTIONS

28       --namespace-id=<NUM>, -n <NUM>
29           Namespace id to use
30
31       --channel-id=<NUM>, -c
32           Channel id
33
34       --lun-id=<NUM>, -l
35           LUN id
36
37       --raw-binary, -b
38           Returns the bad block table in binary form without statistics.
39

EXAMPLES

41       ·   Retrieve bad block table statistics for physical device nvme0,
42           channel 0, and lun 0:
43
44           # nvme lnvm-diag-bbtbl /dev/nvme0 -c 0 -n 0
45
46       ·   Display the bad block table in raw form without statistics for same
47           query:
48
49           # nvme lnvm-diag-bbtbl /dev/nvme0 -c 0 -n 0 -b | hexdump
