.SH "NAME"
nvme-effects-log \- Send NVMe Command Effects log page request, returns result and log
.SH "SYNOPSIS"
.sp
.nf
\fInvme\fR [<global\-options>] \fIeffects\-log\fR <device> [\-\-raw\-binary | \-b]
.fi
.SH "DESCRIPTION"
.sp
Retrieves the NVMe Command Effects log page from an NVMe device and provides the returned structure\&.
.sp
The <device> parameter is mandatory and should be the NVMe character device (ex: /dev/nvme0)\&.
.sp
On success, the returned command effects log structure will be printed for each command that is supported\&.
.SH "OPTIONS"
.PP
\-b, \-\-raw\-binary
.RS 4
This option will print the raw buffer to stdout\&. Structure is not parsed by program\&. This overrides the verbose option\&.
.RE
.SH "GLOBAL OPTIONS"
.sp
The following options are defined at the top\-level nvme command and are available to this subcommand:
.PP
\-\-dry\-run
.RS 4
Print the command that would be executed, but do not actually execute it\&.
.RE
.PP
\-\-no\-ioctl\-probing
.RS 4
Disable probing for 64\-bit IOCTL support\&.
.RE
.PP
\-\-no\-retries
.RS 4
Disable retry logic on transient errors\&.
.RE
.PP
\-o <fmt>, \-\-output\-format=<fmt>
.RS 4
Set the reporting format to
\fInormal\fR,
\fItabular, \*(Aqjson\fR, or
\fIbinary\fR\&. Only one output format may be used at a time\&.
.RE
.PP
\-\-output\-format\-version=<version>
.RS 4
Select the output format version\&. Version
\fI1\fR
uses the original field naming, while version
\fI2\fR
(default) provides more consistent and script\-friendly field names\&.
.RE
.PP
\-\-timeout=<ms>
.RS 4
Set the timeout for the command in milliseconds\&.
.RE
.PP
\-v, \-\-verbose
.RS 4
Increase the level of detail in the output\&. May be specified multiple times to further increase verbosity\&.
.RE
.sp
These options can also be set as machine\-wide defaults in nvme\-cli\&.conf(5)\&. A command\-line flag always overrides the file\&.
.SH "EXAMPLES"
.sp
.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c
.\}
.el \{\
.sp -1
.IP \(bu 2.3
.\}
Print the effects log page in a human readable format:
.sp
.if n \{\
.RS 4
.\}
.nf
# nvme effects\-log /dev/nvme0
.fi
.if n \{\
.RE
.\}
.RE
.sp
.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c
.\}
.el \{\
.sp -1
.IP \(bu 2.3
.\}
Have the program return the raw structure in binary:
.sp
.if n \{\
.RS 4
.\}
.nf
# nvme effects\-log /dev/nvme0 \-\-raw\-binary > effects_log\&.raw
# nvme effects\-log /dev/nvme0 \-b > effects_log\&.raw
.fi
.if n \{\
