<title>Session Management Agent</title>
<h1>Session Management Agent</h1>

The Session Management Agent (SMA) manages the <a href="sc/sci">SCI</a>
private interconnect.  It controls the assignment of SCI node-ids,
IP addresses etc (using sm_config(1M)).<p>

On system bootup, SMA will establish sessions between the various
hosts using the SCI adapters.  SMA supports clusters consisting of
upto 4 nodes.<p>

When Sun Cluster <a href="sc/sc_system">SC</a> is running, SMA will also
manage the highly-available logical network.  If one of the links fails,
SMA will automatically reconfigure the networking drivers to use the
surviving link for all traffic.<p>
