tape drive path keeps going down
Hi, my master server is NBU 7.1 on Windows 2008 R2 SP1. We have more than 10 media servers (Windows 2008 R2 SP1, NBU 7.1). The tape library is IBM TS3310 with 6 FC drives. The tape drives are shared by all the media servers. Recently we found for some tape drives, the paths for drives for some media servers keeps going down. We also saw tape mount error in the tape library. When we manually bring the paths up, they will become down again. We tried to reboot the tape library and the media servers but still see the same error. Does anyone have any idea? Thanks in advance.
