.SH "NAME"
nvme-effects-log \- Send NVMe Command Effects log page request, returns result and log
.SH "SYNOPSIS"
.sp
.nf
\fInvme effects\-log\fR <device> [\-\-output\-format=<fmt> | \-o <fmt>]
                            [\-\-human\-readable | \-H]

.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
\-o <format>, \-\-output\-format=<format>
.RS 4
This option will set the reporting format to normal, json, or binary\&. Only one output format can be used at a time\&.
.RE
.PP
\-H, \-\-human\-readable
.RS 4
This option will parse and format many of the bit fields into a human\-readable format\&.
.RE
.PP
\-b, \-\-raw\-binary
.RS 4
This option will print the raw buffer to stdout\&. Structure is not parsed by program\&. This overrides the human\-readable option\&.

.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 \{\

.\}
.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
