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
