RE: [Veritas-bu] Sg / sgen driver issue
Thanks to everyone who responded to my posting. Turned out that it was NSR.e1200 router configuration in the HP MSL5060 tape library that I needed to change. My previous admin. had configured the router with some WWN-mapping (like the soft zoning in FC switches) to bind it to only specific server's HBA, so that's why I couldn't see all the drives correctly no matter what I tried, although my OS NBU configs all seemed perfect. I thought about this possibility with NSR.e1200 but was reluctant to touch this and this made me delay my backup server migration almost 3 weeks! - Young -Original Message- From: Justin Piszcz [mailto:[EMAIL PROTECTED] Sent: Monday, May 15, 2006 9:08 AM To: Song, Young Cc: veritas-bu@mailman.eng.auburn.edu Subject: Re: [Veritas-bu] Sg / sgen driver issue All the problems I had (initially) w/ fiber zoning was my initial setup of the brocade switch.

[Veritas-bu] Tape drive speed discrepancy problem
I'm having some performance/thruput discrepancy problem with LTO-2 drives and want to seek suggestions to resolve my problems. My backup infrastructure has the following: - Software NBU DataCenter 4.5FP8 - NBU master+media server (running Solaris 8): Sun Fire-280R:PCI1 slot has Dual-Channel Ultra320 SCSI-Channel Card PCI3 slot has Dual-Channel Ultra320 SCSI-Channel Card - Tape Library: Sun L100 w/ 3 x LTO-2 drives w/ LVD SCSI controller And, I have the following physical SCSI connectivity: PCI1 top channel- HP LTO-2 Drive2 in Sun L100 Library PCI1 bottom channel - HP LTO-2 Drive3 in Sun L100 Library PCI3 top channel- HP LTO-2 Drive1 in Sun L100 Library PCI3 bottom channel - Sun L100 Library controller (each SCSI channel is properly terminated with an LVD SCSI terminator) A problem that I'm having is that Drive1 runs at around 24-27MB/sec while Drive2 at 16-17MB/sec to back up the same host at the same time (the 2 drives concurrently running). Any recommendation for this situation? Would getting a 3rd Ultra320 SCSI card and connecting each tape drive from a dedicated SCSI card be something worth trying to resolve this performance discrepancy problem?

[Veritas-bu] Weird tape drive behavior
I just installed a new tape library Sun L100 with 3 x LTO-2 drives and one of the drives keeps showing weird behaviors. I believe I have all the proper SCSI terminations, drive mapping, etc. It tries to mount a tape, position it, but sits there for a long time and fails with the following error: Positioning L01101 to file Error bptm (pid=9063) ioctl (MTWEOF) failed on media id L01101, drive index 0, I/O error (bptm.c.17692) Error bptm (pid=9063) FROZE media id L01101, could not write tape mark to begin new image When I tried using the mt command and run a tar backup on the drive, it went successful and was OK when I tried positioning a tape back and forth to see if I could back up or restore, so I tend to believe that the drive itself may not be bad.

[Veritas-bu] SAP Backup with NetBackup on Solaris/Windows
I have a lot of Solaris Windows machines that run SAP on Oracle or SQL Server. For less mission-critical test and development SAP instances, I'd like to find out what methods other people out there among NetBackup users use to back them up online to either disk or tapes. Is using the standard NetBackup SAP agent software the only option for its online consistent backup and restoration? Or, can anyone share other more cost-effective way? Each NetBackup SAP agent license per host seems to be quite expensive.
