The client runs instances of CA View on multiple LPARs.
When they ran a View backup cycle, for the first time on an LPAR, they received messages:
SARBKT00 Standard backup cycle started for Gen 1 on 07/18/2016 at 16:06:43
SARBKT61 Standard backup cycle starting phase 1
SARTPO42 Device allocation error - ERR=9700, INFO=0000
SARTPO42 Reply Y/N to continue processing with new tape
They believe that SMS is set up correctly.
CA View 12.2
The client found a security error, but no error message had been produced.
They ran an ACF2 SECTRACE.
In the trace, they found an ACF2 rule, set up to protect the SMS storage class incorrectly.
Batch jobs (JOB) could run with the rule as it was, but started tasks (STC) received an error.
Client had their security group fix the ACF2 rule, and tapes could then be mounted with SARSTC with no problems.
