# nvme-lnvm-diag-bbtbl(1)

Diagnose the bad block table

## 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
```
