Hi Sonny, I do not thing it is a config issue. It appears to be a case crashed DASD. What is the wait state code? Are you able to access/browse vol 200 from any other system..do you have an alternate res vol / L1 ready?

After powering it back on Saturday morning, we are unable to IPL from our z9 as we are receiving a " A UNIT CHECK WAS DETECTED". There are no other messages on z9. No error messages on DS6800. Below is IOCDS Config: We are running z/OS 1.12. We are not aware of any changes to IOCDS or the DS6800 for past couple of weeks.

I have spent three trying to debug this problem and any suggestions would be appreciated. We are IPL'ng from ADDRESS: 0200 Which is in CNTLUNIT: 1100 -- CUADD - 01 --- LCU - 01 I am willing to have someone login remotely to review configuration or work with me on telephone to run any type of tests... Any help would be appreciated.
