.SH "NAME"
nvme-capacity-mgmt \- Send capacity management command to configure/create/delete Endurance Groups or NVM Sets, returns results\&.
.SH "SYNOPSIS"

                        [\-\-operation=<operation> | \-O <operation>]

.SH "DESCRIPTION"
.sp
For the NVMe device given, sends a capacity management command to configure/create/delete the Endurance Groups or NVM Sets with the requested operation and element_id\&. On success, if the Operation is Create Endurance group or NVM Set, CQE CDW0 contains Created element identifier else CQE CDW0 is reserved\&.
.sp
The <device> parameter is mandatory and may be either the NVMe character device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1)\&.
.SH "OPTIONS"
.PP
\-O <operation>, \-\-operation=<operation>
.RS 4
Operation to be performed by the controller
.RE
.PP
\-i <element\-id>, \-\-element\-id=<element\-id>
.RS 4
Value specific to the value of the Operation field\&.
.RE
.PP
\-l <cap\-lower>, \-\-cap\-lower=<cap\-lower>
.RS 4
Least significant 32 bits of the capacity in bytes of the Endurance Group or NVM Set to be created
.RE
.PP
\-u <cap\-upper>, \-\-cap\-upper=<cap\-upper>
.RS 4
Most significant 32 bits of the capacity in bytes of the Endurance Group or NVM Set to be created
.RE
.SH "GLOBAL OPTIONS"
.sp
The following options are defined at the top\-level nvme command and are available to this subcommand:
.PP
\-\-dry\-run
.RS 4
Print the command that would be executed, but do not actually execute it\&.
.RE
.PP
\-\-no\-ioctl\-probing
.RS 4
Disable probing for 64\-bit IOCTL support\&.
.RE
.PP
\-\-no\-retries
.RS 4
Disable retry logic on transient errors\&.
.RE
.PP
\-o <fmt>, \-\-output\-format=<fmt>
.RS 4
Set the reporting format to
\fInormal\fR,
\fItabular, \*(Aqjson\fR, or
\fIbinary\fR\&. Only one output format may be used at a time\&.
.RE
.PP
\-\-output\-format\-version=<version>
.RS 4
Select the output format version\&. Version
\fI1\fR
uses the original field naming, while version
\fI2\fR
(default) provides more consistent and script\-friendly field names\&. Other versions are rejected\&.
.RE
.PP
\-\-quiet
.RS 4
Suppress informational messages\&. Errors are still reported, and \-\-quiet cancels any \-\-verbose for the library log level\&.
.RE
.PP
\-\-set\-options=<key=value>[,<key=value>\&...]
.RS 4
Set libnvme library options for this invocation\&. Supported keys are
\fIforce\-4k\fR,
\fImi\-probe\-enabled\fR,
\fItest\-base\-dir\fR
and
\fItest\-sysfs\-dir\fR\&.
.RE
.PP
\-\-timeout=<ms>
.RS 4
Set the timeout for the command in milliseconds\&.
\fIinfinite\fR
or
\fI\-1\fR
waits without a time limit (0xffffffff)\&.
.RE
.PP
\-v, \-\-verbose
.RS 4
Increase the level of detail in the output\&. May be specified multiple times to further increase verbosity\&.
.RE
.sp
These options can also be set as machine\-wide defaults in nvme\-cli\&.conf(5)\&. A command\-line flag always overrides the file\&.
