nvme-id-iocs − Send NVMe Identify I/O Command Set, return result and structure
nvme
id−iocs <device>
[−−controller−id=<cntid> | −c
<cntid>]
[−o <fmt> |
−−output−format=<fmt>]
For the NVMe device given, send an identify command and return the Identify I/O Command Set data structure.
The <device> parameter is mandatory and may be either the NVMe character device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1).
−c <cntid>, −−controller−id=<cntid>
Retrieve the identify I/O Command set data structure for the given cntid. If this value is not given, cntid will be 0xffff.
−H, −−human−readable
This option will parse and format many of the bit fields into human−readable formats.
−o <format>, −−output−format=<format>
Set the reporting format to normal, json, or binary. Only one output format can be used at a time.
• Have the program interpret the returned buffer and display the known fields in a human readable format:
# nvme id−iocs /dev/nvme0
• show the fields in human readable format
# nvme id−iocs /dev/nvme0 −H
