NAME
nvme-capacity-mgmt - Send capacity management command to configure/create/delete Endurance Groups or NVM Sets, returns results.

SYNOPSIS

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>]

DESCRIPTION

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

GLOBAL 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.

--timeout=<ms>
    Set the timeout for the command in milliseconds.

-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.
