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

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

DESCRIPTIONFor 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
