Hmm. Never thought to check persistent binding.  How did you do this in Linux?  What brand of HBAs are you using?

I'll just caution you to make sure you're using persitent binding.  We had a situation on a new Linux media server not configuring device paths for drives. I got a super helpful suggestion from someone in this news group that fixed that problem...but once fixed I was able to see there was a second problem that did not become obvious until after I fixed the first one.
 
In the second problem several of the drives remained unusable even after the paths were finally able to be configured. The cause was that the admin was not using persistent binding because EMC did not recommend it for the LUNS. Being a production box, the admin did not want to go against EMC and change the current setting.
 
The solution is that we have to get an additional HBA, put the drives on it and establish persistent binding (which NBU must have) so the Linux media server can use all the drives. Symantec had no clue what the problem was, but we had an immediate answer once we discused the problem with a group called Versitec.

Is there something specific you are looking to get answered or just experiences?

We're running SLES9SP4 (I'd like to get up to 10SP1, but haven't yet)

We had some issues with init scripts starting on 6.0, but with 6.5 it's been addressed.
It's on a Dell 2650 and is using a QLogic 2342 dual channel fiber card.

It's been really solid.

All,

I'm looking for guidance on using Linux in our NetBackup environment.
We are getting ready to update our current infrastructure.  If we go
with Linux we will use the Dell hardware but I need to know from you is
how the systems should be sized, what HBA's do you recommend, what OS,
does it matter if it is RedHat or SLES?  I backup about 300 TB a month
in my production environment running around 1500 jobs per day, with a
lot of it being Oracle backups.  Any help would be greatly appreciated.

Thanks,
