nvme-wdc-cap-diag(1) ==================== NAME ---- nvme-wdc-cap-diag - Retrieve WDC device's diagnostic log and save to file. SYNOPSIS -------- [verse] 'nvme wdc cap-diag' [--output-file=, -o ] [--transfer-size=, -s ] DESCRIPTION ----------- For the NVMe device given, sends the WDC Vendor Unique Capture-Diagnostics request and saves the result to a file. The parameter is mandatory NVMe character device (ex: /dev/nvme0). This will only work on WDC devices supporting this feature. Results for any other device are undefined. OPTIONS ------- -o :: --output-file=:: Output file; defaults to device serial number followed by "cap_diag" suffix -s :: --transfer-size=:: Transfer size; defaults to 0x10000 (65536 decimal) bytes EXAMPLES -------- * Gets the capture diagnostics log from the device and saves to default file in current directory (e.g. STM00019F3F9cap_diag.bin): + ------------ # nvme wdc cap-diag /dev/nvme0 ------------ * Gets the capture diagnostics log from the device and saves to defined file in current directory (e.g. testSTM00019F3F9cap_diag.bin): + ------------ # nvme wdc cap-diag /dev/nvme0 -o test ------------ * Gets the capture diagnostics log from the device and saves to defined file with pathname (e.g. /tmp/testSTM00019F3F9cap_diag.bin): + ------------ # nvme wdc cap-diag /dev/nvme0 -o /tmp/test ------------ * Gets the capture diagnostics log from the device transferring the data in 64k chunks and saves to default file in current directory (e.g. STM00019F3F9internal_fw_log.bin): + ------------ # nvme wdc cap-diag /dev/nvme0 -s 0x10000 ------------ * Gets the capture diagnostics log from the device transferring the data in 16k chunks and saves to default file in current directory (e.g. STM00019F3F9internal_fw_log.bin): + ------------ # nvme wdc cap-diag /dev/nvme0 -s 16384 ------------ NVME ---- Part of the nvme-user suite.
