While writing a dump copy of volume volser1 to dump class class, DFSMSdss encountered a permanent I/O error. The dump tape volume where the error occurred is volser2. The dump copy is invalidated, and the volumes will be internally deleted by the DELVOL command. For the completely filled volumes, if TAPEDELETION for dump is SCRATCHTAPE, the volumes are returned to the scratch pool. If TAPEDELETION for dump is HSMTAPE, the DELVOL processing is equivalent to the REASSIGN parameter of the DELVOL command. For the volume that was being written on when the error was encountered (volser2), the volume has its contents invalidated and is marked unavailable for selection. This message is issued for each dump copy that has a permanent I/O error.
If this was the last or only dump class receiving output for this dump, the dump function ends. If at least one valid dump copy still remains, the dump function continues until completion or until no more good copies exist. DFSMShsm processing continues.
If a dump copy is required in this dump class, retry the operation after corrective action has been taken.
