.SH "NAME"
nvme-toshiba-vs-internal-log \- Retrieve a Toshiba device\*(Aqs vendor specific internal log and either save to file or dump the contents\&.
.SH "SYNOPSIS"
.sp
.nf
\*(Aqnvme toshiba vs\-internal\-log \*(Aq <device>
[\-\-output\-file=<FILE>, \-o <FILE>] (optional)
[\-\-saved\-log, \-s] (optional)
.fi
.SH "DESCRIPTION"
.sp
For the NVMe device given, sends the Toshiba internal device log request and either saves the result to a file or dumps the content to stdout\&.
.sp
The <device> parameter is mandatory and may be either the NVMe character device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1)\&.
.sp
The log is associated with the controller rather than any namespaces\&.
.sp
Two logs exist, the current log and the previous log\&.
.sp
This will only work on Toshiba devices supporting this feature\&.
.sp
Note: The logs are quite large \- typically 100\(cqs of MB\&. This command can take several minutes to complete\&. A progress runner is included when data is written to file and a page count is included in the stdout dump\&.
.SH "OPTIONS"
.PP
\-o <FILE>, \-\-output\-file=<FILE>
.RS 4
Output binary file\&. Defaults to text\-formatted dump to stdout
.RE
.PP
\-p, \-\-prev\-log
.RS 4
Use previous log contents\&. Defaults to the current log contents\&.

.sp
.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c
.\}
.el \{\
.sp -1
.IP \(bu 2.3

Get the current log from the device and dump it to stdout:
.sp
.if n \{\

.nf
# nvme toshiba internal\-log /dev/nvme0

.if n \{\

Get the previous log from the device and save to a binary file:
.sp
.if n \{\
.RS 4
.\}
.nf
# nvme toshiba internal\-log /dev/nvme0 \-\-output\-file=log\&.bin \-\-prev\-log
