REMCS Agent Operator's Guide 1.5

2.1.2 eXtended System Control Facility(XSCF) notification

XSCF (eXtended System Control Facility) can send failure information to REMCS Center without use of the REMCS Agent.

XSCF is a system monitor/control facility that consists of processors independent of the CPU on a server. Even though a system failure or serious failure that prevents normal operation of OS occurs, this function is still able to send notification. The REMCS Agent is usually communicating with the REMCS Center. If the REMCS Agent is not available, XSCF communicates with the center in its' place. As a result, errors can be detected more completely and earlier, thereby providing improved remote customer support. Refer to "eXtended System Control Facility User's Guide" for XSCF.
