I have a very dynamic lab environment with several z/VM systems and a lot of shared DASD that can change from day to day. DASD is always being varied online and attached to one system or another. z/VM IPL's are not scheduled but can happen at any time. Here is the problem. Often DASD that was varied online and used by z/VM-x is no longer there after it IPL's... I don't want to have everything online for each VM at IPL.
Here is the question for discussion. I thought that I could setup a 'SHUTTRAP' machine that would query dasd whan it receives a shutdown signal and save the results in a file. Then later when z/VM comes back up I can have AUTOLOG1 recreate the DASD environment from the shuttrap file before autologing the other gueste.. Any ideas? Comments? Thanks
