Used to put our archivelogs on netapps now we do it on SAN. For the most
part the SAN has been flawless. A couple weeks ago we did have an issue
writing to the SAN for a couple hours. The San reported no errors and the
problem went away after a couple hours. I am not convinced it was the SAN at
all.
Sounds like Dick just had a recent setup..so it might just be some setup
issues that usually occur in new implementations of something.

So the problems that Brian and Dick are reporting are when using NFS over
SAN ?
{both say that they "used to use NetApp" and now use "SAN"} ?
I run 9iRAC (Linux) on NetApp with , obviously, the archivelogs also on the
same NetApp filer
and haven't had issues.

Actually, we did the same thing..used to use Netapp and now we use
SAN. We have used a couple of SANs now ...
OOPS, my feeble memory is jogged, I actually just had a similar
problem you are having... eek, just a couple weeks ago.
Ok.. the admin and I scratched heads for 2.5hrs and then it started
working again.... thought it actually was RMAN writing the backup to there
(and the Rman archivelog backup).
We never got to the bottom of it. We were thinking of putting
sniffer on the network to check for bottlenecks but the problem has not
shown up since.

New wrinkle to add to the pile, caught me off guard too. This use
to be a NFS mount to a Net Appliance system. It was moved over the weekend
to a SAN mount pointon the CX500. Still NFS though.

Network? Not sure I can help at this point..looks like some
directed troubleshooting...
Also.. onetime I think we had a problem... we rebooted our server
from where the NFS mounts were done which helped.

Brian,
Yes we can write files on the NFS mount, and the syslogs have
nothing in them. But the DB sure is having a pile of fun with it. Alter
log says it's creating the archive log, but nothing shows up and the db just
hangs.

Yes we are... and no problems.
One weapon we are finding useful is the 10G OEM.. does server
parameter comparisons...ie..did the ghost admin change something..? Even
when we catch them.. it slides like water off the ducks back cause they are
on the top of the food chain. Always.. I remember there are some settings to
make sure NFS can accommodate issue (forget the details now.. something
about async). I would do some testing..can you copy files there, write there
...have the Admin check the syslog and so on..
