Tape RAID issues

[chaiyunfat]

Hello!
I am curious if anyone else has seen this issue. I have inherited an Exabyte 430m library with 4 mammoth 2 drives. The drives are setup in a raid wo/parity using ArcServe 2000. We have had some issues with backups failing due to "failing to grab media" errors. We have also seen some major errors where the tape device will dissappear from the RAID group and have to be readded. This has happened twice now. The first time I had IBM replace the drive. The same error has occurred and now IM not sure what the issue is. It is the same drive which is causing the issue. Possible bad cable?? I wouldnt think so but you never know. Has this happened to any of you?

Thank you,
Chai
