Get LBA Status from NVMe device


nvme get-lba-status <device> [--namespace-id=<nsid> | -n <nsid>]
                        [--start-lba=<slba> | -s <slba>]
                        [--max-dw=<max-dw> | -m <max-dw>]
                        [--action=<action-type> | -a <action-type>]
                        [--range-len=<range-len> | -l <range-len>]
                        [--timeout=<timeout> | -t <timeout>]
                        [--output-format=<fmt> | -o <fmt>] [--verbose | -v]


For the NVMe device given, send an nvme Get LBA Status admin command and provides the results.

The <device> parameter is mandatory and may be either the NVMe character device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1).

On success, the returned get lba data structure may be returned in one of several ways depending on the option flags; the structure may parsed by the program and printed in a readable format or the raw buffer may be printed to stdout for another program to parse.


-n <nsid>, --namespace-id=<nsid>

Send the Get LBA Status command for the specified nsid. This can be used to override the default value for either character device (unspecified) or the block device (result from NVME_IOCTL_ID).

-s <slba>, --start-lba=<slba>

Starting LBA(SLBA) in 64-bit address of the first logical block addressed

-m <max-dw>, --max-dw=<max-dw>

Maximum Number of Dwords(MNDW) specifies maximum number of dwords to return

-a <action-type>, --action=<action-type>

Action Type(ATYPE) specifies the mechanism it uses in determining the LBA Status Descriptors.

-l <range-len>, --range-len=<range-len>

Range Length(RL) specifies the length of the range of contiguous LBAs beginning at SLBA

-t <timeout>, --timeout=<timeout>

Override default timeout value. In milliseconds.

-o <fmt>, --output-format=<fmt>

Set the reporting format to normal, json or binary. Only one output format can be used at a time.

-v, ā€‰--verbose

Increase the information detail in the output.
