NAME

6       nvme-wdc-get-pfail-dump - Retrieve WDC device's pfail crash dump.
7

SYNOPSIS

9       nvme wdc get-pfail-dump <device> [--output-file=<FILE>, -o <FILE>]
10

DESCRIPTION

12       For the NVMe device given, sends the WDC vendor unique pfail crash dump
13       request and saves the result to file. In current implementation pfail
14       crash dump is captured if it is present. On success it will save the
15       dump in file with appropriate suffix. Note that this command will clear
16       the available dump from the device on success.
17
18       The <device> parameter is mandatory NVMe character device (ex:
19       /dev/nvme0).
20
21       This will only work on WDC devices supporting this feature. Results for
22       any other device are undefined.
23

OPTIONS

25       -o <FILE>, --output-file=<FILE>
26           Output file; defaults to device serial number followed by
27           "pfail_dump" suffix
28

EXAMPLES

30       ·   Gets the pfail crash dump from the device and saves to default file
31           in current directory (e.g. STM00019F3F9_pfail_dump.bin):
32
33               # nvme wdc get-pfail-dump /dev/nvme0
34
35       ·   Gets the pfail crash dump from the device and saves to defined file
36           in current directory (e.g. testSTM00019F3F9_pfail_dump.bin):
37
38               # nvme wdc get-pfail-dump /dev/nvme0 -o test
39
40       ·   Gets the pfail crash dump from the device and saves to defined file
41           with pathname (e.g. /tmp/testSTM00019F3F9_pfail_dump.bin):
42
43               # nvme wdc get-pfail-dump /dev/nvme0 -o /tmp/test
