DESCRIPTION
|
||
|
|
-----------
|
||
|
|
For the NVMe device given, sends an Data Set Management command and
|
||
|
|
provides the result and returned structure.
|
||
|
|
|
||
|
|
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, the `'--namespace-id'` option is
|
||
|
|
mandatory, otherwise it will use the ns-id of the namespace for the block
|
||
|
|
device you opened. For block devices, the ns-id used can be overridden
|
||
|
|
with the same option.
|
||
|
|
|
||
|
|
You must specify at least one of the values for range list. If the range
|
||
|
|
lists provided do not list the same number of elements, the default
|
||
|
|
values for the remaining in the range will be set to 0.
|
||
|
|
|
||
|
|
The command dword 11 may be provided at the command line. For convenience,
|
||
|
|
the current defined attributes (discard, integral read/write) for a
|
||
|
|
data-set management have flags. If cdw11 is specified, this will override
|
||
|
|
any settings from the flags may have provided.
|
||
|
|
|
||
|
|

-b <nlb-list,>::
|
||
|
|
--blocks=<nlb-list,>::
|
||
|

|
|
Comma separated list of the starting block in each range
|
||
|
|
|
||
|
|
-d <deallocate>::
|
||
|
|
--ad=<deallocate>::
|
||
|
|

|
--idw=<write>::
|
||
|
|

||
|
|
|
||
|
|
-r <read>::
|
||
|
|
--idr=<read>::
|
||
|
|
Attribute Integral Dataset for Read.
|
||
|
|
|
||
|
|
-c <cdw11>::
|
||
|
|
--cdw11=<cdw11>::
|
||
