NVME-CREATE-NS(1) NVMe Manual NVME-CREATE-NS(1) NAME nvme-create-ns - Send NVMe Namespace management command to create namespace, returns results. SYNOPSIS nvme create-ns <device> [--nsze=<nsze> | -s <nsze>] [--ncap=<ncap> | -c <ncap>] [--flbas=<flbas> | -f <flbas>] [--dps=<dps> | -d <dps>] [--nmic=<nmic> | -m <nmic>] [--anagrp-id=<anagrpid> | -a <anagrpid>] [--nvmset-id=<nvmsetid> | -i <nvmsetid>] [--endg-id=<endgid> | -e <endgid>] [--csi=<command_set_identifier> | -y <command_set_identifier>] [--lbstm=<lbstm> | -l <lbstm>] [--nphndls=<nphndls> | -n <nphndls>] [--block-size=<block-size> | -b <block-size>] [--timeout=<timeout> | -t <timeout>] [--nsze-si=<nsze-si> | -S <nsze-si>] [--ncap-si=<ncap-si> | -C <ncap-si>] [--azr | -z] [--rar=<rar> | -r <rar>] [--ror=<ror> | -O <ror>] [--rnumzrwa=<rnumzrwa> | -u <rnumzrwa>] [--phndls=<placement-handle-list,> | -p <placement-handle-list,>] [--output-format=<fmt> | -o <fmt>] [--verbose | -v] 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. -e <endgid>, --endg-id=<endgid> This field specifies the identifier of the endurance group. -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 (aligned on 1Mib boundaries, unless the controller recommends a smaller value). 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 (aligned on 1Mib boundaries, unless the controller recommends a smaller value). 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. -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. -t <timeout>, --timeout=<timeout> Override default timeout value 120,000. In milliseconds.
