Hi Guys,
It turns out Dell so called Pro Support is...m... SH#T!!! It's very unPro support!!!
Why? They spent more than 1 week try to figure out whats wrong and I found something myself, which they should pickup in the first second I mentioned the issue. It's in their DOCO!! I checked Release Note of TL2000... And guess what, under Known Issues, it has these few lines:
• TL2000/TL4000 – LT05 library drives may fail during the verify portion of the backup job
Job failures may occur during the verify portion of the backup in Symantec BUE 12.5 and 2010. Although the entire backup job fails, the backup portion does complete successfully and there is no loss of data. This is due to Symantec not having the appropriate timeout value for the Dell™ PowerVault™ LTO5-140 Tape Drive.
• TL2000/TL4000 – LT05 library drives with and 6Gbps SAS HBA receives a controller error
The 6Gbps SAS HBA with firmware version 07.01.24.00 issues a firmware reset for the HBA, which causes Symantec to post a warning “driver detected a controller error on raid port xx”. This is a recoverable warning in which the drive and HBA resumes operation without intervention.
So, for anyone out there try to use Symantec Backup with LTO5 tapes, AVOID TL2000 or Dell !!! Unless you can leave backup job UNVERIFIED!
I suppose Symantec will provide a hotfix for the issue soon?
