If you can get a test system up, extract the duplicate volumrd from the master trace table,

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.
