ALARM '02: 3745 IPL FAILED CCU-x
hhmmss ref code
Cause:
Action:
• Main storage
• CCU
• MOSS hardware
• Channel adapter
• Controller load/dump program errors.
• A link IPL port was not defined properly. Refer to the MOSS LKP function in the 3745
Advanced Operations Guide.
• A cable may not be attached to the port you defined as link IPL port.
• An IPL performed on a remote controller linked to a local controller by a switched X.21
link, an X.2S (SVC/PVC) link, or a token-ring (a link IPL port is only valid for SOLC or
nonswitched X.21 links).
• In case of a loading problem on channel attached controller:
- Perform IPL again.
- If the problem persists;
r.a
and give reference code.
• In case of a loading problem on link attached controller:
1. Through a switched/nonswitched SOLCor a nonswitched X.21 link:
Check the link IPL port definition. Refer to the MOSS LKP function in the
3745
Advanced Operations Guide.
r.a
and give reference code if not corrected.
2. Through a switched X.21 link, an X.25 (SVC/PVC) link, or a token-ring:
An initial loading of the remote controller is 'required. Refer to
3720/3745
Remote Loading/Activation Guide SA33-0161 for the procedure.
r.a
and give reference code if not corrected.
