NAME
|
||||
----
|
||||
nvme-wdc-vs-internal-log - Retrieve WDC device's internal firmware log and save to file.
|
||||
|
||||
SYNOPSIS
|
||||
--------
|
||||
[verse]
|
||||
'nvme wdc vs-internal-log' <device> [--output-file=<FILE>, -o <FILE>] [--transfer-size=<SIZE>, -s <SIZE>]
|
||||
[--data-area=<DATA AREA>, -d <DATA_AREA>] [--file-size=<FILE SIZE>, -f <FILE SIZE>] [--offset=<OFFSET>, -e <OFFSET>]
|
||||
[--type=<TYPE>, -t <type>] [--verbose, -v]
|
||||
|
||||
DESCRIPTION
|
||||
-----------
|
||||
|
||||
For the NVMe device given, sends the WDC Vendor Specific Internal Log 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 "_internal_fw_log_<date>_<time>.bin" suffix
|
||||
|
||||
-s <SIZE>::
|
||||
--transfer-size=<SIZE>::
|
||||
Transfer size; defaults to 0x10000 (65536 decimal) bytes
|
||||
|
||||
-d <DATA AREA>::
|
||||
--data-area=<DATA AREA>::
|
||||
DUI data area to retrieve. The DUI data areas from 1 to <DATA AREA> will be retrieved. This parameter
|
||||
is currently only supported on the SN340, SN640, and SN840 devices.
|
||||
|
||||
-f <FILE SIZE>::
|
||||
--file-size=<FILE SIZE>::
|
||||
Specifies the desired size of the data file starting at the passed in offset. This allows the user to
|
||||
retrieve the data in several smaller files of the passed in size. This parameter is currently only
|
||||
supported on the SN340 device.
|
||||
|
||||
-e <OFFSET>::
|
||||
--offset=<OFFSET>::
|
||||
Specifies the data offset at which to start retrieving the data. This parameter is used in combination
|
||||
with the file size parameter to retrieve the data in several smaller files. This parameter is currently
|
||||
only supported on the SN340 device.
|
||||
|
||||
-t <TYPE>::
|
||||
--type=<TYPE>::
|
||||
Specifies the telemetry type - NONE, HOST, or CONTROLLER. This parameter is used to get either the host
|
||||
generated or controller initiated telemetry log page. If not specified or none is specified, the command
|
||||
will return the default E6 log data. This parameter is currently only supported on the SN640 and SN840
|
||||
devices.
|
||||
|
||||
-v <VERBOSE>::
|
||||
--verbose=<VERBOSE>::
|
||||
Provides additional debug messages for certain drives.
|
||||
|
||||
EXAMPLES
|
||||
--------
|
||||
* Gets the internal firmware log from the device and saves to default file in current directory (e.g. STM00019F3F9_internal_fw_log_20171127_095704.bin):
|
||||
+
|
||||
------------
|
||||
# nvme wdc vs-internal-log /dev/nvme0
|
||||
------------
|
||||
* Gets the internal firmware log from the device and saves to defined file in current directory (e.g. test.bin):
|
||||
+
|
||||
------------
|
||||
# nvme wdc vs-internal-log /dev/nvme0 -o test.bin
|
||||
------------
|
||||
* Gets the internal firmware log from the device and saves to defined file with pathname (e.g. /tmp/test):
|
||||
+
|
||||
------------
|
||||
# nvme wdc vs-internal-log /dev/nvme0 -o /tmp/test
|
||||
------------
|
||||
* Gets the internal firmware log from the device transferring the data in 64k chunks and saves to default file in current directory (e.g. STM00019F3F9_internal_fw_log_20171127_100754.bin):
|
||||
+
|
||||
------------
|
||||
# nvme wdc vs-internal-log /dev/nvme0 -s 0x10000
|
||||
------------
|
||||
* Gets the internal firmware log from the device transferring the data in 16k chunks and saves to default file in current directory (e.g. STM00019F3F9_internal_fw_log_20171127_100950.bin):
|
||||
+
|
||||
------------
|
||||
# nvme wdc vs-internal-log /dev/nvme0 -s 16384
|
||||
------------
|
||||

|
||||
+
|
||||
------------
|
||||
# nvme wdc vs-internal-log /dev/nvme0 -d 3 -f 0x1000000 -t 0x0000000 -o /tmp/sn340_dui_data_1.bin

|
||||
------------
|
||||
* Gets the host telemetry log page to data area 3 from the device and stores it in file host-telem-log-da3.bin:
|
||||
+
|
||||
------------
|
||||
# nvme wdc vs-internal-log /dev/nvme1 -t host -o host-telem-log-da3.bin -d 3
|
||||
------------
|
||||
* Gets the controller telemetry log page to data area 3 from the device and stores it in file ctlr-telem-log-da3.bin:
|
||||
+
|
||||
------------
|
||||
# nvme wdc vs-internal-log /dev/nvme1 -t controller -o ctlr-telem-log-da3.bin -d 3
