NAME

       nvme-attach-ns - Send NVMe attach namespace, return result.

SYNOPSIS

       nvme attach-ns <device> [--namespace-id=<nsid> | -n <nsid>]
                               [--controllers=<ctrl-list,> | -c <ctrl-list,>]
                               [--output-format=<fmt> | -o <fmt>] [--verbose | -v]

DESCRIPTION

       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.

       -c <ctrl-list,>, -controllers=<ctrl-list,>
           The comma separated list of controller identifiers to attach the namespace too. If no list is
           provided, the namespace will be attached to the <device> controller used for this command.

       -o <fmt>, --output-format=<fmt>
           Set the reporting format to normal, json or binary. Only one output format can be used at a time.

       -v, --verbose
           Increase the information detail in the output.

EXAMPLES

           Attach namespace 2 to the controllers with id 0x21 and 0x22:

           # nvme attach-ns /dev/nvme1 -n 0x2 -c 0x21,0x22

           Attach namespace 3 to nvme0:

           # nvme attach-ns /dev/nvme0 -n 3
