Re: [Veritas-bu] SAN Switch Change caused NBU7 to lose tape drives
Hello, even we have no experience in NBU7, I think the behavior is similar as in NBU 6.5 - the thing is the FC-ID. In this FC-ID the Domain-ID of the Switch is encoded, so the change you made resulted in different FC-IDs. On an AIX System those IDs are used. It was possible to delete the drives in NetBackup and to delete the device, but not create new devices. We simply had stop NetBackup on that machine, then we were able to delete and rescan the drives on the OS. After a new Start of NetBackup we were able to create the drives again. Good luck, Hans-Peter ___ Veritas-bu maillist - Veritas-bu@mailman.eng.auburn.edu http://mailman.eng.auburn.edu/mailman/listinfo/veritas-bu
Re: [Veritas-bu] SAN Switch Change caused NBU7 to lose tape drives
Not sure on the Windows side, as that sounds like hardware/firmware. However, on the Solaris media server try running tpautoconf -report_disc Its possible EMM is having issues with the new WWNs being presented and thinks some of the drives are duplicates. Fairly easy to clean up once you know what EMM is thinking: http://seer.entsupport.symantec.com/docs/271366.htm - Original Message - From: Brandon35 netbackup-fo...@backupcentral.com To: VERITAS-BU@MAILMAN.ENG.AUBURN.EDU Sent: Wednesday, July 7, 2010 10:03:53 PM Subject: [Veritas-bu] SAN Switch Change caused NBU7 to lose tape drives Hi everyone, In one of my environments we replaced our old SAN switch with a new Cisco.

Re: [Veritas-bu] SAN Switch Change caused NBU7 to lose tape drives
Unix - on aix if I had done that I would bet my tape drive would have gone from avail to defined - where defined says it is in the database but cannot see the physical. So I would have removed it and run cfgmgr to rediscovery the tape drives. Not sure how that works on Solaris As to windows, I have see it do that. Even when the device manager says it sees all the tape drives I have to have the windows admin go Computer management Storage Removable storage Libraries And he as to do something there to make those drives work again.

Re: [Veritas-bu] SAN Switch Change caused NBU7 to lose tape drives
1. make sure all services are running. 2. try deleting devices drive/robot from the GUi. If it fails you can use vmglob -delete xxx from a command line. Once the devices are removed. 3. Run scan or sgscan in /volmgr/bin You should see a robot and x number of drives. Note: if you don't see devices call the system administrator to check the storage/San presentation for the devices. 4. Once the O/S can see the devices run tpautoconf from volmgr/bin You should have drives and robot again.

The -1 -1 -1 says that it has lost the info on the drive.

Once that is done double click it again and open it up Now choose add Choose your media server It should show you ONLY that tape drive that matches via serial number.
