NAME

nvme-device-self-test − Perform the necessary tests to observe the performance and the parameters

SYNOPSIS

nvme device−self−test <device> [−−namespace−id=<NUM> | −n <NUM>]
[−−self−test−code=<NUM> | −s <NUM>] [−−wait | −w]

DESCRIPTION

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.

OPTIONS

−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.

EXAMPLES

• 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
