.SH "DESCRIPTION"
.sp
Starts a recording or playback session.  The recording session records the platform\(cqs
ACPI NFIT, PCAT, PMTT tables, SMBIOS tables, and FIS mailbox transactions that
occur during the recording session.  The normal use\-case would be to start a recording
session, execute commands (e.g., create \-goal, show \-sensors, etc.) to be recorded,
dump the recorded session using the [Dump Session] command, followed by stopping
the session using the [Stop Session] command. The "dumped" session can then be
loaded and "played" back on any platform that can execute the ipmctl tool.
.sp
The playback session has two modes: \fIplayback\fP and \fIplayback_manual\fP.  The \fIplayback\fP
mode will automatically execute all commands that were previously recorded.  The
\fIplayback_manual\fP mode allows commands to be executed one at a time in a manual
fashion.  If a tag is given, the playback will begin at the command that corresponds
with the tagID.  Note, the [Show Session] command displays the order and
commands to execute, where the \fI*\fP denotes which command to execute next.

.SH "LIMITATIONS"
.sp
Recordings should be played back on the same IPMCTL version that created the recording.
Recordings taken in UEFI should be played back in the UEFI environment (simulated or real).
Recordings taken in an OS are binary compatible with other OS versions of IPMCTL (i.e., recording
taken in Linux* can be played back in Windows*).
.SH "RETURN DATA"
.sp
In \fIplayback\fP mode the output will be a concatenation of the output from each played back command.
