Did you by any chance zone the devices into multiple HBA ports in the new config but not the old? Perhaps you had powerpath, DMP or some kind of multipath software installed before?
By the way - there shouldn't be any problems with seeing multiple devices and NB will only use the ones configured and it shouldn't actually go an configure 16 robots and 400 drives. The device config wizard will know that some are the same devices - atleast it does in my environment. Have you let the device config wizard finish - what does it actually configure after detecting all the devices? -----Original Message----- From: veritas-bu-boun...@mailman.eng.auburn.edu [mailto:veritas-bu-boun...@mailman.eng.auburn.edu] On Behalf Of Heathe Yeakley Sent: 23 September 2010 15:39 To: NetBackup Mailing List Subject: Re: [Veritas-bu] Device Recognition in RHEL5/NBU7 To clarify my question: I currently have a live NetBackup environment where the master server is a Dell 2950 and I have two media servers that are solaris boxes running RHEL 4. My department wants to decommission the older boxes and move NetBackup to newer boxes, and I wanted to upgrade to 7.0 anyway, so I decided to kill two birds with one stone and build 1 new master and 2 new media, install NBU 7 on the new environment and then zone my existing libraries into the new environment and then point all the servers I'm backing up to the new environment. On my live NetBackup environment (the RHEL4 one), when I go into the NBU hardware configuration wizard and scan for devices, the wizard comes back and says it sees 3 libraries and 92 drives (which is the number I expect to see). When I shut down my live environment and bring up the NBU 7 environment and run the hardware wizard, it sees like 16 robots and 400 drives. I'm trying to figure out why my NBU 6.0/RHEL4 environment is able to see one device file per robot/tape drive, but my NBU 7/RHEL5 environment thinks each path is 1 device. I'm not sure where to begin researching this issue. I'm in the process of skimming through the NBU 7 device configuration manual, the HBA documentation and Red Hat's storage documentation. Any light that can be shed on this will be greatly appreciated. - HKY _______________________________________________ Veritas-bu maillist - Veritas-bu@mailman.eng.auburn.edu http://mailman.eng.auburn.edu/mailman/listinfo/veritas-bu _______________________________________________ Veritas-bu maillist - Veritas-bu@mailman.eng.auburn.edu http://mailman.eng.auburn.edu/mailman/listinfo/veritas-bu
