Hi All,

 

We have an old USP subsystem which is EOSL. Recently the following SIM arrived:

Reference code: 73fe01

Error Section: Processor failure / SVP failure

Error Detail: DKC processor status unviewable and uncontrollable

Error Location: CHA-1E, MP# = 1

Action Code: 4DA00000 LAN ADAPTER     SVP-BASIC

 

In Maintenance CM/SM path is flashing which shows the following for both clusters:

From the Action Code I think SVP need to be replaced but manual doesn't say it for sure. Unfortunately there is a disk failure and disk cannot be replaced since this CM/SM path problem. When we try to replace disk after "DKU Inline is running" the following error appears:

Does anybody has experience what to replace to solve the CM/SM path failure?

 

ps: after inspecting the LAN connection diagram it seems CSW-1D is the problem, but it's not for sure, SVP can be the problem too.

 

Cheers,

Csaba
