Since your DASD is given to your 2nd level DR guests via DEVNO your 1st level system doesn't care what the label is. I submit that varying them OFF/ON is not needed at all. We've conducted many DR tests as 2nd level guests, relabeling every volume, and never cared what label the 1st level system thought it was. When interfacing with the 1st level provider refe r to addresses not labels. Brian Nielsen

NJE connection to RSCS or NJE Bridge would also work (without having to write any code).

Don't forget TLS/SSL + userid + password. If user is validated, then issue the FOR command and send the response back. The good news is that if you have RACF on both z/OS and z/VM, you can generate a PassTicket on the z/OS side and use it to authenticate on z/VM. Alan Altmark z/VM Development IBM Endicott
Re: Issuing VM commands from z/OS...
A simple REXX based socket listener running on a disconnected z/VM guest could accomplish this quite easily. Commands can be sent from z/OS directly (or any other platform) from a Batch Job/TSO or the console via System REXX.

Issuing VM commands from z/OS...
...I know that I can do this easily from z/VSE, but what about z/OS? Let me explain further. This past Saturday, we performed our first DR test with our current setup (1 z/OS system and 1 z/VM with multiple-z/VSE). Since we have not been able to get the backup performance from either z/VM or z/VSE that z/OS provides, we backup both systems (2 z9s) from z/OS. During recovery, the z/OS system DSF's all devices to LABEL them and then restores them from the library. Well, the setup is a z/VM "floor" system with z/OS and "our" z/VM under it. All of the DASD is MDISK DEVNO'ed in 1st level VM. After a DASD label has changed it's not reflected on the 1st level VM until a VARY OFF/ON is performed. Since z/OS is performing the labeling, it would be best for it to do the VARY OFF/ON. Other thoughts? Frank M.
