Backup Exec 2012 SBE to Ultrium LTO2 problems after Hotfix 201596
About the environment:
Server: Acer Altos G330 Mk2. 4GB RAM. Plenty of RAID 5 storage.
Backup device: HP Ultrium LTO2 internal SAS drive.
OS: Windows Server 2003 SBS SP2 (fuly patched as of March 2013).
Backup Exec: 2012 SBE SP1 with all Hotfixes to date.
Everything was working perfectly, (read as well as can be expected in BENT 2012!) until I installed the above hotfix. Backups had been running reliably at a rate of 1.4GB/min. The same night, after applying the above hotfix, the performace plumeted to only 400MB/min.
Symantec support have git me to try running tests in NTBackup. However, the drive isn't appearing properly in Windows Rmovable Storage Manager. The drive looks good in Device Manager, but RSM seems to think the drive is offline. Symantec said, the problem is with Windows and that they won't escalate the case until it works corectly in Windows. I uninstalled the device and allowe Windows to redetect it, with the HP drivers. Immediately the drive appears in RSM and works in NTBackup (albeit at only 400Mb/min). Reinstall the Symantec drivers and immediately RSM can't see the drive properly again.
Is there anybody out there also experiencing issues, with this hotfix, of this nature?
