nvme-log-changed-alloc-ns-list1
Send nvme changed allocated namespace list log page request, returns result and log.
Usage
nvme [<global-options>]
log
changed-alloc-ns-list
<device>
[{--raw-binary | -b}]
Overview
Retrieves the NVMe Changed Allocated 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 Allocated 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.
Options
-
-b, --raw-binary -
Print the raw Changed Namespace List log buffer to stdout.
Options
The following options are defined at the top-level nvme command and are available to this subcommand:
-
--dry-run -
Print the command that would be executed, but do not actually execute it.
-
--no-ioctl-probing -
Disable probing for 64-bit IOCTL support.
-
--no-retries -
Disable retry logic on transient errors.
-
-o <fmt>, --output-format=<fmt> -
Set the reporting format to normal, tabular, 'json, or binary. Only one output format may be used at a time.
-
--output-format-version=<version> -
Select the output format version. Version 1 uses the original field naming, while version 2 (default) provides more consistent and script-friendly field names. Other versions are rejected.
-
--quiet -
Suppress informational messages. Errors are still reported, and --quiet cancels any --verbose for the library log level.
-
--set-options=<key=value>[,<key=value>...] -
Set libnvme library options for this invocation. Supported keys are force-4k, mi-probe-enabled, test-base-dir and test-sysfs-dir.
-
--timeout=<ms> -
Set the timeout for the command in milliseconds. infinite or -1 waits without a time limit (0xffffffff).
-
-v, --verbose -
Increase the level of detail in the output. May be specified multiple times to further increase verbosity.
These options can also be set as machine-wide defaults in nvme-cli.conf(5). A command-line flag always overrides the file.
Examples
• Print the Changed Allocated Namespace List Log page in a human readable format:
# nvme log changed-alloc-ns-list /dev/nvme0
• Print the raw Changed Allocated Namespace List log to a file:
# nvme log changed-alloc-ns-list /dev/nvme0 --raw-binary > log.raw
It is probably a bad idea to not redirect stdout when using this mode.
