MSL-5026 Issues. Opening robot door puts tape drives in off-line status.

We have an MSL-5026 Robot Library connected to a NSR1200 storage router connected to a MSA1000 SAN. We are running Backup Exec 9.1 on 4 servers connected to the SAN each running backups jobs to the Robot Library. They are unfortunately also mission crytical servers running Windows 2000 Server, SQL and Exchange 2000.

I have an issue where, when I unlock the Library to change tapes, the robot and tape drives go off-line. The only resolution is to restart all the servers connected to it or is some cases, restart the Backup Exec services. On occation when the Robot is opened, a server will loose it's connection to the SAN!! And the SAN drives wil disappear and only a reboot connects them. There are errors in the event viewer indicating that the drives went off-line the moment I open the Robot doors. I have recently upgraded the Tape Drivers device drivers (Using Veritas Drivers)firmware, NS1200 firmware, server HBA drivers and Firmware and still the problem persists.

Any comments would be greatly appreciated.
