Dear Sirs,
I have an issue regarding Symantec Backup Exec at a customer.
Current IT Infrastructure at the customer:
- VMware ESX 4.1 infrastructure (100% patched) - approx. 10 Virtual Machines (100% patched)
- Management Server (physical) - Windows Server 2008 R2 SP1 (100% patched), 2 HP LTO4 Ultrium tape drives (each connected to separate SCSI interface/card) (latest drivers/firmware) (checked at HP for any issues)
- Symantec Backup Exec 2010 R2 SP1 (100% patched) (Agents used: VMware ESX, Exchange, SQL and Windows Server)
4 jobs:
Backup to Disk (copy of VMware infrastructure to disk part 1 - folder 1) (scheduled at 17:00)
Backup to Disk (copy of VMware infrastructure to disk part 2 - folder 2) (scheduled at 17:00)
Backup to Tape (copy of VMware infrastructure to tape part 1 - tape device 1) (scheduled at 03:00)
Backup to Tape (copy of VMware infrastructure to tape part 2 - tape device 2) (scheduled at 03:00)
Problem I currently have: The first 2 jobs always run without any problems. But the 3rd and 4th job sometimes fail to complete with the following error:
The job failed with the following error: A communications failure has occurred between the Backup Exec job engine and the remote agent.
Error reported: A device attached to the system is not functioning.
V-79-57344-34036 - An unknown error has occurred.
I’ve tested the tape drives with the LTT software from HP. No errors were encountered during a full test read/write to tape.
