VM:Backup for z/VM VM:Backup High-Speed Disaster Recovery Option (HiDRO)


DAILY backup abended with "EC 4D5" that occurred during the first SFS filespace. All other tasks were successfully executed.

We moved  a couple of minidisks in our VM during the day which required a shutdown of the SFS server. The HIDRO server had not been restarted.

Might that be the cause of the HiDRO abend?

Yes, it's quite possible the SFS server being shut down while HiDRO had access to the FilePool is what caused the abend.

Any interruption to the SFS server could cause a job to abend.
