<div class="paragraph"><p>For the NVMe device given, send an nvme Format Namespace admin command
|
|
|
|
|
|
and provides the results.</p></div>
|
|
|
|
|
|
<div class="paragraph"><p>The <device> parameter is mandatory and may be either the NVMe character
|
|
|
|
|
|
device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1).
|
|
|
|
|
|
If the character device is given, and the controller does not support
|
|
|
|
|
|
formatting of particular namespaces (ID_CTRL.FNA bit 0 enabled), then all
|
|
|
|
|
|
namespaces will be formatted. If FNA is disabled, then the namespace
|
|
|
|
|
|
identifier must be specified with the <em>namespace-id</em> option; specify a
|
|
|
|
|
|
value of 0xffffffff to send the format to all namespaces. If the block
|
|
|
|
|
|
device is given, the namespace identifier will default to the namespace
|
|
|
|
|
|
ID of the block device given, but can be overridden with the same option.</p></div>
|
|
|
|
|
|
<div class="paragraph"><p>Note, the numeric suffix on the character device, for example the <em>0</em> in
|
|
|
|
|
|
/dev/nvme0, does NOT indicate this device handle is the parent controller
|
|
|
|
|
|
of any namespaces with the same suffix. The namespace handle’s numeral
|
|
|
|
|
|
may be coming from the subsystem identifier, which is independent of the
|
|
|
|
|
|
controller’s identifier. Do not assume any particular device relationship
|
|
|
|
|
|
based on their names. If you do, you may irrevocably erase data on an
|
|
|
|
|
|
unintended device.</p></div>
|
|
|
|
|
|
<div class="paragraph"><p>On success, the program will automatically issue BLKRRPART ioctl to
|
|
|
|
|
|
force rescanning the namespaces. If the driver is recent enough, this will
|
|
|
|
|
|
automatically update the physical block size. If it is not recent enough,
|
|
|
|
|
|
you will need to remove and rescan your device some other way for the
|
|
|
|
|
|
new block size to be visible, if the size was changed with this command.</p></div>
