.SH "DESCRIPTION"
|
|
.sp
|
|
Retrieves the log pages from an NVMe device corresponding to the requested self\-test by the user and provides 20\-most recent result returned structure\&.
|
|
.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)\&.
|
|
.sp
|
|
On success, the returned log structure may be returned in one of several ways depending on the option flags; the structure may parsed by the program and printed in a readable format or the raw buffer or the json format\&.
|

.sp
|
|
By default the log is printed out in the normal readable format\&.
