nvme-device-self-test − Perform the necessary tests to observe the performance and the parameters
nvme
device−self−test <device>
[−−namespace−id=<NUM> | −n
<NUM>]
[−−self−test−code=<NUM> |
−s <NUM>] [−−wait | −w]
Initiates the required test based on the user input.
The <device> parameter is mandatory and may be either the NVMe character device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1).
On success, the corresponding test is initiated.
−n <NUM>, −−namespace−id=<NUM>
Indicate the namespace in which the device self−test has to be carried out
−s <NUM>, −−self−test−code=<NUM>
This field specifies the action taken by the device self−test command : 0h: Show current state of device self−test operation 1h: Start a short device self−test operation 2h: Start a extended device self−test operation eh: Start a vendor specific device self−test operation fh: Abort the device self−test operation Default is 0h.
−w, −−wait
Wait for the device self test to complete before exiting The device self−test is aborted by SIGINT signal interrupt for the wait The option is ignored if the abort self−test code option specified.
• Start a short device self−test in the namespace−id 1:
# nvme device−self−test /dev/nvme0 −n 1 −s 1
• Abort the device self−test operation in the namespace−id 1:
# nvme device−self−test /dev/nvme0 −n 1 −s 0xf
