System is Veritas Netbackup 5.1 MP6 1 Master/Media server running on Windows 2003 standard edition, SP1 Library is a Qualstar TLS-8466 with 4 drives. 2 LTOII that are attached to our Fibre Channel SAN via a SCSI to fibre bridge, 2 LTOIII that are directly fibre attached to our SAN. All are going through a McData Spherion 4500.
Seemingly random issue that is occuring is that on occasion our LTOIII drives will be reported in Netbackup as down. What I am looking for is, what are the correct Netbackup processes to activate logging on to get some troubleshooting information? The drive doesn't report as having any problems from the library's perspective, and there are no error messages on the fabric switches. The Netbackup server is zoned to each fibre port in the library individually, so there are 3 zones: Netbackup server to SCSI to fibre bridge (Controls robotic arm, and 2 LTOII drives) Netbackup server to LTOIII drive 1 Netbackup server to LTOIII drive 2. We never have any issues with the LTOII drives or the robotic arm, but the LTOIII drives go down for seemingly no reason whatsoever. Any assistance with troubleshooting this issue is greatly appreciated. Thanks in advance!
