I am currently testing an Overland Tape storage unit with a LTO-3 drive on CentOS 4.4. After a random amount of time but usually when we have backed up about 0.5-1TB we get scsi errors which cause the backup to fail. I have rebuilt the box with Solaris 10 x86 and Windoze to prove the hardware and have successfully backed up over 3TB on each OS without error. Can anyone offer advice on how to find out what is causing the error in CentOS.
Your best bet to track down exactly what those errors mean would be to head over to the linux-scsi list. But I can tell you that I've been using an Overland LTO3 library on centos-4 for over a year now with very good results. The 2 main differences are that I'm using an x86_64 server (I doubt that makes much difference) and an LSI 21320 HBA. I have had nothing but good luck with LSI adapters, and I think it'd be worth it for you to give one a shot.
I will say this, though. If you plan on ever using 2 drives in the library, get the 22320, which has 2 external channels. I've been tearing my hair out trying to get both drives in my library to write at full speed at the same time, and no matter what driver tweaks I make, I just can't get it to go. My 22320 arrives today, and I'm rather hoping that'll fix the problem.
