Initialization and Recovery

The procedure to get a system out of SPE-Down mode follows.
NOTE:
This is important! If you cannot complete the first step or have problems
with the maintenance interface, then replace the Processor circuit pack. In a
high or critical reliability system the DUPINT-A circuit pack can also cause
SPE-Down. Remember that you need to obtain a new license file any time
you replace the processor circuit pack.
1. If the alarms indicate a tape failure, replace the tape or tape drive and go to
Step 3. Otherwise, verify that there is a good tape in the tape drive. If a
tape is not present or if either the tape or tape drive is defective, then
restarting the system using the reset command causes the system to go
down again.
2. In a High or Critical Reliability system, select a carrier to repair first.
When it is possible to accurately determine the location of the problem, use
the display alarms [a | b] command to display alarms for both SPEs and
check the red LEDs on the processor complex circuit packs. Select the
carrier where the red LEDs indicate the circuit pack alarmed. Bring up the
system on that carrier and then refer to Standby SPE Maintenance
documentation to repair the Standby SPE.
In a Standard Reliability system or after a carrier is chosen in a High or
Critical Reliability system, determine which circuit pack is defective by
displaying alarms and observing the red LEDs (as discussed previously).
Depending on the alarms, use
Table 4-1 on page 4-11 to replace the circuit
packs indicated, one by one, in the order shown.
