All
I
have 18 large Media Servers, all Win2k3, single TL with SSO and 12 drives. I
tend to sort out most problems without bringing the whole lot
down.
When I do maintenance on the library, I shutdown all of the NBU Services
first, then power down the library.
Once the library is up, I then re-run device manager to scan for new
hardware, and the drives and library come into play on each Media Server..... In
most cases this can be done remotely. Once the server sees the library, start
the Master and then media servers and check drive status. In almost all cases,
everything has come up fine. Yes a little pain, but its done in such an Art, it
rarely takes that long to do this task.
The one issue I had a problem with involved performing a scsi reset while
NetBackup was idle due to a drive in a complete mixed state that could not
recover from manually. (cant find the technote, but its a scsi release command
to be done on all affected drive(s)).
Apart from this, its mostly trouble
free. If its working, I leave things well
alone. The environment is 5.1 and soon to be moved to 6.x and if 6.x is as
better than 5.1, then I look forward to this upgrade to make Admin Life easier.
I agree, getting the right hardware and configuration in place is a
must.

I agree with Randy, I've had a lot of issues with the
Media/SAN Media Windows servers. I would recommend that if you are pre 6.x,
examine your backup requirements for each server and use teaming (I have also
experienced problems with these) or Gig NICs when you can. Not only
will this solution save you money, but it will also save you administration
headache, regardless of Media server platform, when you do run into
problems.

NetBackup doesn't "get it" until version 6. I am
100% windows here with a mixture of 19 Media and SAN Media servers sharing a
library with 24 drives. First, stabilize it. Zone your library and
make sure that the only servers that can even see the library are servers that
you want to see the library. Check HBA settings and disable
removable storage service. Until you have the communication paths really
stable between servers and drives, the problems won’t ever cease. But once
you have it stable, it typically will stay that way.
However, in version 5.1, whenever I had to do any type of
maintenance on my library causing it to lose connection to NetBackup servers, I
had to reboot all of my NetBackup servers before I could get NetBackup to see
the library again. My SAN Media servers are high profile servers and
rebooting them periodically wasn’t a popular activity with our customers.
Microsoft said it wasn’t Windows, Symantec said it wasn’t NetBackup and I could
never get a straight answer. But 6.0 doesn’t have that problem. I
can reboot the library all day long and as soon as it is back on line, NetBackup
is back on line.
Thanks,
Randy

for SSO in NBU 5.1
but would you implement such a large sso environment with
Windows servers? we've shared 20,30,40 drives across many windows servers
and it becomes hell whenever drives go offline and/or is replaced and then
shuffles in the os. we've used persistent binding but this doesn't help
with vtl drives. but sometimes, netbackup just doesn't get
it.
