nvme-changed-ns-list-log − Send NVMe Changed Namespace List log page request, returns result and log.
nvme
changed−ns−list−log <device>
[−−raw−binary | −b]
[−−output−format=<fmt> | −o
<fmt>]
Retrieves the NVMe Changed Namespace List log page from an NVMe device and provides the returned structure.
The <device> parameter is mandatory and must be a NVMe character device (ex: /dev/nvme0).
On success, the returned Changed Namespace List log 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.
−b, −−raw−binary
Print the raw Changed Namespace List log buffer to stdout.
−o <format>, −−output−format=<format>
Set the reporting format to normal, json, or binary. Only one output format can be used at a time.
• Print the Changed Namespace List Log page in a human readable format:
# nvme changed−ns−list−log /dev/nvme0
• Print the raw Changed Namespace List log to a file:
# nvme changed−ns−list−log /dev/nvme0 −−raw−binary > log.raw
It is probably a bad idea to not redirect stdout when using this mode.
