Andrew, We finally found the problem - bad drive in the ROBOT. It was not apparent from our tracking tools (so much for those softwares). It took continous batch job abends which raised our suspicion. We had the drive checked and found a defective R/W head. Thanks to all who responded to my post.

This will tell you if DFSMSdss is invoking ICKDSF to init the volumes instead of simply issuing the FCWITHDRAW after the DUMP is completed. If ICKDSF is being invoked, it is because the VTOC tracks of the DASD volume are in a target FlashCopy relationship, and issuing an FCWITHDRAW against them could well cause the volume to be online but invalid (because the VTOC location now contains the residual data from before the FlashCopy was done to it).
