nvme-wdc-vs-error-reason-identifier - Man Page

nvme wdc vs-error-reason-identifier <device> [--log-id=<NUM>, -i <NUM>] [--file=<FILE>, -o <FILE>]

For the NVMe device given, retrieve the telemetry log error reason id field for either the host generated or controller initiated log​. The controller initiated telemetry log page option must be enabled to retrieve the error reason id for that log page id​.

The <device> parameter is mandatory and must be the NVMe character device (ex: /dev/nvme0)​.

This will only work on WDC devices supporting this feature​. Results for any other device are undefined​.

On success it returns 0, error code otherwise​.

-i <id>, --log-id=<id>

Specifies the telemetry log id of the error reason identifier to retrieve​. Use id 7 for the host generated log page​. Use id 8 for the controller initiated log page​. The default is 7/host generated

-o <FILE>, --output-file=<FILE>

Output file; defaults to "<device serial number>_error_reason_identifier_host_<date>_<time>​.bin" for the host generated log or "<device serial number>_error_reason_identifier_ctlr_<date>_<time>​.bin" for the controller initiated log​.

• Retrieves the host generated error reason identifier field and save it in file host_gen_error_reason_id​.bin​.

  # nvme wdc vs-error-reason-identifier /dev/nvme0 -i 7 -o host_gen_error_reason_id​.bin

• Retrieves the controller initiated error reason identifier field and save it in file ctlr_init_error_reason_id​.bin​.

  # nvme wdc vs-error-reason-identifier /dev/nvme0 -i 8 -o ctlr_init_error_reason_id​.bin
