NAME

       nvme-wdc-vs-error-reason-identifier - Retrieve WDC device's telemetry log error reason
       identifier field

SYNOPSIS

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

DESCRIPTION

       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.

OPTIONS

       -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.

EXAMPLES

       •   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
