NVME-WDC-CAP-DIAG(1) NVMe Manual NVME-WDC-CAP-DIAG(1) NAME nvme-wdc-cap-diag - Retrieve WDC device's diagnostic log and save to file. SYNOPSIS nvme wdc cap-diag <device> [--output-file=<FILE>, -o <FILE>] [--transfer-size=<SIZE>, -s <SIZE>] DESCRIPTION For the NVMe device given, sends the WDC Vendor Unique Capture-Diagnostics request and saves the result to a file. The <device> 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 <FILE>, --output-file=<FILE> Output file; defaults to device serial number followed by "cap_diag" suffix -s <SIZE>, --transfer-size=<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.
