Hi, I have an old program that was created for a different purpose, but may be helpful to your needs. It was created to put devices ONLINE or OFFLINE based on the volser mask. For instance, if running in production, disks with volser P* were made ONLINE, while having any other volser label, they were put offline. It was created for a very small environment with all disks shared, and based on where running and the masks desired, the disks were made online or not.
This program uses UCBSCAN macro to detect and filter the devices. If you believe it fits your needs, send me a note, and I'll send you the code.

Right now Test LPAR is down and we are needing to restart / ReIPL the Test LPAR but getting many duplicate volsers during IPL process. I'm looking for tool / utility that I can use / run from Production LPAR that will list out all duplicate volsers and related unit addresses within the defined DASD environment - of course this means the utility needs to interrogate all configured DASD volumes whether online or not. Anything out there? - I tried ISMF and don't see a way to do thru the ISPF interface but possibly a trick or two with ISMF I'm not aware of? Anyways open to any / all ideas - have to believe there is a way. Possibly CBT? Thanks as always.
