DESCRIPTION

25       For the NVMe device given, sends a namespace management command to
26       create the namespace with the requested settings. On success, the
27       namespace identifier assigned by the controller is returned.
28
29       The <device> parameter is mandatory and may be either the NVMe
30       character device (ex: /dev/nvme0), or a namespace block device (ex:
31       /dev/nvme0n1).
32

OPTIONS

34       -s, --nsze
35           The namespace size.
36
37       -c, --ncap
38           The namespace capacity.
39
40       -f, --flbas
41           The namespace formatted logical block size setting. Conflicts with
42           --block-size argument.
43
44       -d, --dps
45           The data protection settings.
46
47       -m, --nmic
48           Namespace multipath and sharing capabilities.
49
50       -a, --anagrp-id
51           ANA Group Identifier. If this value is 0h specifies that the
52           controller determines the value to use
53
54       -i <nvmsetid>, --nvmset-id=<nvmsetid>
55           This field specifies the identifier of the NVM Set.
56
57       -y <command_set_identifier>, --csi=<command_set_identifier>
58           This field specifies the identifier of command set. if not issued,
59           NVM Command Set will be selected.
60
61       -l <lbstm>, --lbstm=<lbstm>
62           Logical Block Storage Tag Mask for end-to-end protection.
63
64       -b, --block-size
65           Target block size the new namespace should be formatted as.
66           Potential FLBAS values will be values will be scanned and the
67           lowest numbered will be selected for the create-ns operation.
68           Conflicts with --flbas argument.
69
70       -S, --nsze-si
71           The namespace size (NSZE) in standard SI units. The value SI
72           suffixed is divided by the namespace LBA size to set as NSZE. If
73           the value not suffixed it is set as same with the nsze option.
74
75       -C, --ncap-si
76           The namespace capacity (NCAP) in standard SI units. The value SI
77           suffixed is divided by the namespace LBA size to set as NCAP. If
78           the value not suffixed it is set as same with the ncap option.
79

EXAMPLES

81       •   Create a namespace:

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