                        [--namespace-id=<nsid> | -n <nsid>]


                        [--crkey=<crkey> | -c <crkey>]


                        [--rtype=<rtype> | -t <rtype>]


                        [--rrela=<rrela> | -a <rrela>]

DESCRIPTION

The Reservation Release command is used to release or clear a reservation held on a namespace.

OPTIONS

-n <nsid>, --namespace-id=<nsid>

Override the nsid field. If using the admin character device, this parameter is required.

-c <crkey>, --crkey=<crkey>

Current Reservation Key: If the Reservation Register Action is 001b (i.e., Unregister Reservation Key) or 010b (i.e., Replace Reservation Key), then this field contains the current reservation key associated with the host. For all other Reservation Register Action values, this field is reserved. The controller ignores the value of this field when the Ignore Existing Key (IEKEY) bit is set to ‘1’.

-t <rtype>, --rtype=<rtype>

Reservation Type: This field specifies the type of reservation to be created.
Value Definition
0h Reserved
1h Write Exclusive Reservation
2h Exclusive Access Reservation
3h Write Exclusive - Registrants Only Reservation
4h Exclusive Access - Registrants Only Reservation
5h Write Exclusive - All Registrants Reservation
6h Exclusive Access - All Registrants Reservation
07h-FFh Reserved

-a <rrela>, --rrela=<rrela>

Reservation Release Action: This field specifies the registration action that is performed by the command.
Value Definition
0 Release
1 Clear
2-7 Reserved

-i, --iekey

Ignore Existing Key: If this bit is set to a 1, then the Current Reservation Key (CRKEY) check is disabled and the command shall succeed regardless of the CRKEY field value.

Indicator option, defaults to 0.

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.
