CBR6420I   OAM failed to establish address space ASID=asid as a secondary address space.

Explanation

OAM executed an SSAR (set secondary address space register) instruction to establish a user address space as a secondary address space in preparation of moving data to or from the OAM address space and the user address space. The SSAR instruction failed. It is likely that the user address space is no longer active.

System action

OAM stops trying to cross-memory-copy information into the address space asid which encountered the error.

Operator response

Notify the system programmer.

System programmer response

Investigate the state of address space asid. It is possible that address space abnormally terminated for some reason, or perhaps simply terminated before OAM was able to report completion status on all of the work that address space had previously submitted to OAM.
