DESCRIPTION

       For the NVMe device given, sends a namespace management command to create the namespace
       with the requested settings. On success, the namespace identifier assigned by the
       controller is returned.

       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

       -s, --nsze
           The namespace size.

       -c, --ncap
           The namespace capacity.

       -f, --flbas
           The namespace formatted logical block size setting. Conflicts with --block-size
           argument.

       -d, --dps
           The data protection settings.

       -m, --nmic
           Namespace multipath and sharing capabilities.

       -a, --anagrp-id
           ANA Group Identifier. If this value is 0h specifies that the controller determines the
           value to use

       -i <nvmsetid>, --nvmset-id=<nvmsetid>
           This field specifies the identifier of the NVM Set.

       -y <command_set_identifier>, --csi=<command_set_identifier>
           This field specifies the identifier of command set. if not issued, NVM Command Set
           will be selected.

       -l <lbstm>, --lbstm=<lbstm>
           Logical Block Storage Tag Mask for end-to-end protection.

       -n <nphndls>, --nphndls=<nphndls>
           Number of Placement Handle included in the Placement Handle List. If the Flexible Data
           Placement capability is not supported or not enabled in specified Endurance Group,
           then the controller shall ignore this field.

       -b, --block-size
           Target block size the new namespace should be formatted as. Potential FLBAS values
           will be values will be scanned and the lowest numbered will be selected for the
           create-ns operation. Conflicts with --flbas argument.

       -S, --nsze-si
           The namespace size (NSZE) in standard SI units. The value SI suffixed is divided by
           the namespace LBA size to set as NSZE. If the value not suffixed it is set as same
           with the nsze option.

       -C, --ncap-si
           The namespace capacity (NCAP) in standard SI units. The value SI suffixed is divided
           by the namespace LBA size to set as NCAP. If the value not suffixed it is set as same
           with the ncap option.

       -z, --azr
           Allocate ZRWA Resources. If set to 1, then the namespace is to be created with the
           number of ZRWA resource specified in the RNUMZRWA field of this data structure. If
           cleared to 0, then no ZRWA resources are allocated to the namespace to be created.

       -r <rar>, --rar=<rar>
           Requested Active Resources. This field specifies the number of active resources to be
           allocated to the created namespace.

       -o <ror>, --ror=<ror>
           Requested Open Resources. This field specifies the number of open resources to be
           allocated to the created namespace.

       -u <rnumzrwa>, --rnumzrwa=<rnumzrwa>
           Requested Number of ZRWA Resources. This field specifies the number of ZRWA resources
           to be allocated to the created namespace.

       -p <placement-handle-list,>, --phndls=<placement-handle-list,>
           The comma separated list of Reclaim Unit Handle Identifier to be associated with each
           Placement Handle.

EXAMPLES

       •   Create a namespace:

               # nvme create-ns /dev/nvme0 --nsze 11995709440 --ncap 1199570940 --flbas 0 --dps 0 --nmic 0
               # nvme create-ns /dev/nvme0 --nsze-si 6.14T --ncap 1199570940 --flbas 0 --dps 0 --nmic 0
