Determining the Time of a Spontaneous
Interchange
There are two ways to tell at what time a spontaneous interchange has taken
place:
■
Display initcauses
The display initcauses command displays a record of every system reset.
In the following example, a spontaneous interchange into Server B took
place at 2:53 p.m. The standby server (B) transitioned into active mode
with a WARM restart (reset level 1).
Examining the Alarm and Error Logs
The system may have had time to log alarms or errors against the fault that
caused the interchange. Proceed through the steps summarized in
Examine only major alarms with a timestamp near the time of interchange, and
whose carrier designation is the current standby server [the “switch processing
element” (SPE) interchanged out of]. Include any resolved alarms meeting this
description.
