Re: [Veritas-bu] Device Recognition in RHEL5/NBU7
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.

Re: [Veritas-bu] Device Recognition in RHEL5/NBU7
As far as the zoning in the old environment, I've gone over both with a fine tooth comb and it looks like I've zoned both environments exactly alike. As far as multipath software, I have device mapper multipath configured on both environments. As far as letting the wizard finish, I decided to try that and about halfway through the wizard, NetBackup realized it's all the same devices and presented me with 3 robots and 92 drives (the correct number). I'm still confused why my 6.0 environment sees 3 robots and 92 drives after the first scan on the 2nd page of the Hardware configuration wizard whereas my 7.0 environment has to go about halfway through before it sees all the devices as 3 robots and 92 drives But hey, at least it's working now. - HKY On Fri, Sep 24, 2010 at 5:39 AM, Shekel Tal tal.she...@uk.fujitsu.com wrote: Did you by any chance zone the devices into multiple HBA ports in the new config but not the old?

I know that the version I am on 6.5.5 see's the multiple paths you have described. It could just be a change in behaviour from within NB?

[Veritas-bu] Device Recognition in RHEL5/NBU7
I've just finished building a new NetBackup environment. NBU is 7.0 and the OS is Red Hat Enterprise 5. When I brought up the NBU interface to configure the libraries, I'm seeing each one of my libraries multiple times. I have 1 master and 2 media servers. Each has 4 Qlogic HBAs in them. I've zoned all 4 of the HBAs in the master and the first 2 in both media (I'm going to use the other 2 HBAs for SAN clients). I've double checked my SAN zoning and multipathd config in Red Hat and everything looks fine to me. I have a feeling this is going to be a 'doh!' moment when I finally figure out the issue. Anyone else out there running Fibre Channel drives in RHEL? What do you do to get the OS to just see 1 device with multiple paths instead of thinking each path = 1 device?

Hello, Use this technote to configure the library http://www.symantec.com/docs/TECH73944 And multiple tape paths are recognized by netbackup correctly. Of course all paths does not work together. Netbackup choose the path that will be used.
