nvme-ns-attach1
Send nvme attach namespace, return result.
Usage
nvme [<global-options>]
ns
attach
<device>
[{--namespace-id=<nsid> | -n
<nsid>}]
[{--controllers=<ctrl-list,> | -c
<ctrl-list,>}]
Overview
For the NVMe device given, sends the nvme namespace attach command for the provided namespace identifier, attaching to the provided list of controller identifiers.
The <device> parameter is mandatory NVMe character device (ex: /dev/nvme0) but not a namespace block device (ex: /dev/nvme0n1).
Options
-
-n <nsid>, --namespace-id=<nsid> -
The namespace identifier to attach but not attached already. The broadcast value 0xffffffff can also be given as all or -1.
-
-c <ctrl-list,>, --controllers=<ctrl-list,> -
The comma separated list of controller identifiers to attach the namespace to. If no list is provided, the namespace will be attached to the <device> controller used for this command.
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
Attach namespace 2 to the controllers with id 0x21 and 0x22:
# nvme ns attach /dev/nvme1 -n 0x2 -c 0x21,0x22
Attach namespace 3 to nvme0:
# nvme ns attach /dev/nvme0 -n 3
