NAME
       nvme-wdc-namespace-resize - Resizes the device's namespace.

SYNOPSIS
       nvme wdc namespace-resize <device> [--nsid=<NAMESPACE ID>, -n <NAMSPACE ID>]
                               [--op_option=<OP OPTION>, -o <OP OPTION>]

DESCRIPTION
       For the NVMe device given, sends the WDC Vendor Specific Command that
       modifies the namespace size reported the device.

       The <device> parameter is mandatory NVMe character device (ex:
       /dev/nvme0).

       This will only work on WDC devices supporting this feature. Results for
       any other device are undefined.

OPTIONS
       -n <NAMESPACE ID>, --namespace-id=<NAMESPACE_ID>
           Namespace ID; ID of the namespace to resize

       -o <OP OPTION>, --op-option=<OP OPTION>
           Overprovisioning Option; defaults to 0xF Valid Values: 0x1 - 7% of
           Original TNVMCAP reported value 0x2 - 28% of Original TNVMCAP
           reported value 0x3 - 50% of Original TNVMCAP reported value 0xF -
           0% of Original TNVMCAP reported value (original config) All other

EXAMPLES
       o   Resizes namespace 1 to 50% of the original TNVMCAP reported value:

               # nvme wdc namespace-resize /dev/nvme0 -n 1 -o 3

       o   Resizes namespace 2 to 7% of the original TNVMCAP reported value:

               # nvme wdc namespace-resize /dev/nvme0 --namespace-id=2 --op-option=1
