Starting CAS9 (after bringing online new IBM Storage Unit) , getting the following abend:
IEF450I CAS9 CAS9 - ABEND=S0C1 U0000 REASON=00000001
Release : ANY
Component : CCS390 - CA COMMON SERVICES FOR Z/OS
This was a case of mixed maintenance. Attempts to create a new linklist and refreshing LLA would not correct the issue.
What finally corrected the issue was the 15.0 Common Services load libraries were removed from the boot up linklist and an IPL was performed.
