|
SYNOPSIS
|
|
--------
|
|
[verse]
|
|
'nvme wdc cap-diag' <device> [--output-file=<FILE>, -o <FILE>] [--transfer-size=<SIZE>, -s <SIZE>]

-------
|
|
-o <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):
