nvme-capacity-mgmt1
Send capacity management command to configure/create/delete endurance groups or nvm sets, returns results.
Usage
nvme [<global-options>]
capacity-mgmt
<device>
[{--operation=<operation> | -O
<operation>}]
[{--element-id=<element-id> | -i
<element-id>}]
[{--cap-lower=<cap-lower> | -l
<cap-lower>}]
[{--cap-upper=<cap-upper> | -u
<cap-upper>}]
Overview
For the NVMe device given, sends a capacity management command to configure/create/delete the Endurance Groups or NVM Sets with the requested operation and element_id. On success, if the Operation is Create Endurance group or NVM Set, CQE CDW0 contains Created element identifier else CQE CDW0 is reserved.
The <device> parameter is mandatory and may be either the NVMe character device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1).
Options
-
-O <operation>, --operation=<operation> -
Operation to be performed by the controller
-
-i <element-id>, --element-id=<element-id> -
Value specific to the value of the Operation field.
-
-l <cap-lower>, --cap-lower=<cap-lower> -
Least significant 32 bits of the capacity in bytes of the Endurance Group or NVM Set to be created
-
-u <cap-upper>, --cap-upper=<cap-upper> -
Most significant 32 bits of the capacity in bytes of the Endurance Group or NVM Set to be created
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.
