Hmmmm - wondering from all the comments - When I say "discover" I'm
talking about at the OS level (/proc/scsi/qla2300 - we're using Qlogic
fibre cards).   Due to the oddities there never went to NetBackup -
sounds as if some of you made it past this point.

Subject: RE: [Veritas-bu] Linux as a master/media server

I had tape drive discovery issues on our Linux Media server as well.  If
the drives are in use by another server, Linux will not be able to
discover them, even if it knew about them before.  Therefore, if you
ever have to boot the Linux system that is a media server, it becomes a
problem.  BTW, We have a SAN (fiber) environment as well.  If Linux were
the Master server, I'd update my resume and start looking.  If you're
really comfortable with Linux and understand what it needs to function
properly, go for it.  I'm not.  Just my 2 cents.

We attempted to use Linux (RedHat EL AS 3) as a media server for our
setup which is SAN using Connectrix and Surestore to an L700.
Unfortunately it doesn't seem to discover all the drives correctly so we
gave up and do network backups on it.   This despite the fact we were
able to get the Linux server to access the Clariion array storage over
the fibre SAN. 

Oddly enough the other night I attended the local Unix users group
meeting which has many of the same members as the local Linux users
group.   I asked about this very issue and was told that Linux doesn't
do well with fibre.   They said that it appears that it recognizes
devices by a very specific array of information so subtle differences
such as the firmware level on one device can make it undiscoverable.

I'm not saying it's impossible but it appears that unless you buy an out
of the box solution designed specifically for Linux you may not be able
to do it.  I think Dell may sell this as in our installation they were
surprised to find out we weren't going to be using their library.   They
do have documentation for how to setup their library for Linux.

Subject: [Veritas-bu] Linux as a master/media server

I'm considering replacing my aging Solaris box with a Linux system.
Does anyone have any opinions on how well Veritas supports Linux as a
Master server, Media server, or both.  In the past it seemed some
features were only available in Solaris, but I can't recall specifics.

Currently I have an L700e with ACSLS for library control.  I'm
especially interested in any of the tape drive whackiness that might
exist in Linux since Veritas is relatively new to Veritas on Linux
(compared to Solaris).

How about mixing media/master servers.... keeping my master server as a
Solaris box, with Linux media servers???
