Possible conditions
The central-side (C-side) peripheral
module (PM) cannot communicate
with the SMS.
The computing module (CM) detects
that unit 0 is active, but unit 1 is
inactive. This means that the CM has
not detected the occurrence of a
SWACT. The CM busies and
returns-to-service (RTS) both units.
The CM has the units return with the
active/inactive unit configuration of the
original CM.
The internal state of the active unit is
not ready. The state is busy, restart,
or synchronize. This condition
identifies a software error. The CM
BSYs and RTSs both the SMS and
the C-side links. The CM tries to
return the SMS and C-side links to
service.
A system-generated SWACT
occurred, normally because of a trap
or facility audit.
Unit failed test (TST) or RTS.
Unit-to-unit communication failed.
The system cannot perform a warm
SWACT.
One of the background hardware
audits detects a fault.
A warm SWACT occurred.
An error occurred on a DS-1 link to
the unit. The unit waits for a
maintenance system reset.
