ControlFile Troubleshooting (continued)
Condition Action
Coordinator
Processor s tarts but
stops after a short
period of time.
ControlFile appears
on the ControlFile
Status screen and
then disappears.
1. Pull out the two PeerWay Buffer cards in the ControlFile.
2. Reseat the Coordinator Processor and Nonvolatile
Memory cards and try to restart the Coordinator
Processor.
3. If the Coordinator Processor now starts and runs, check
the Control Block Directory screens (a configuration key
must be used when viewing the screens) of all other
ControlFiles on the PeerWay for corrupted data. Look
for scrambled loop tags and abnormal block status and
dynamic memory sizes.
4. If a suspect c ontroller is located, the Kill Controller
function must be performed on all Controller Processors
in that cage. After the Kill Controller has been
performed, the plant configuration must be reloaded from
the disk to the ControlFile.
5. With the PeerWay Buffers cards still removed, disable
and remove all Controller Processor cards within the
faulty cage.
6. Reseat the Coordinator Processor and Nonvolatile
Memory cards and try to start just these two cards. If the
Coordinator Processor will not stay running, replace it.
7. If the Coordinator Processor now starts and runs, begin
installing the Controller Processor cards one at a time.
As each card is installed, restart the Coordinator
Processor and Controller Processor cards (this is done
to determine if one of the Controller Processors is
preventing the Coordinator Processor from running).
8. If a Controller Processor is found that prevents the
Coordinator Processor from running, reseat and start the
Coordinator Processor and Nonvolatile Memory cards
with all Controller Processors set to DISABLE. After the
Coordinator Processor is running, reinstall the PeerWay
Buffer cards and perform the Wipe Bubble command for
all Controller Processors in the ControlFile.
9. Turn all Controller Processors to ENABLE and allow
them to restart. If one of the Controller Processors will
not start, or if it will not allow the Coordinator Processor
to start, replace that Controller Processor card.
10. After the ControlFile is running with all of its Controller
Processors, load the Plant Configuration from disk for
that ControlFile.
