Hi Ed, I believe you're right in that you're in a catch-22 with z/OS based ISKLM servers. If your DC has a complete power down and the DS8Ks need to get keys before coming up and those keys are on z/OS that needs the DS8K up to IPL you're going to have trouble. That's why we're reliant on a Windows box (2 actually) to serve our keys. If the people who installed your DS8K(s) set it up, there's a recovery key that can be used in an emergency to bring the DS8K up without the ISKLM servers running. Never had to use it so I don't know what the process would be but that's the purpose for the recovery key.

I assumed ISKLM would not be usable for DASD because of the "catch-22" situation of needing the DASD to IPL z/OS. Suppose we had a complete power down of the computer room. Could we still somehow IPL z/OS from DASD that has not yet contacted its z/OS-based SKLM? Thanks... -- Phoenix Software International Edward E.
