Hmmm... SANs don't use NFS or any other network protocol. They look like a
local disk to the systems connected to it. Could it be NAS they are using?
Those require a network protocol, such as NFS or SMB.

So the problems that Brian and Dick are reporting are when usingNFS 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 onthe same
NetApp filer
and haven't had issues.

Actually, we did the samething..used to use Netapp and now we use SAN. We have
used a couple ofSANs now ...
OOPS, my feeble memory isjogged, I actually just had a similar problem you are
having...eek, just a couple weeks ago.
Ok.. the admin and I scratchedheads for 2.5hrs and then it started working
again.... thought itactually was RMAN writing the backup to there (and the Rman
archivelogbackup).
We never got to the bottom ofit. We were thinking of putting sniffer on the
network to check forbottlenecks 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 NetAppliance system. It was moved over the weekend to a SAN
mountpointon the CX500. Still NFS though.

Network? Not sure I canhelp at this point..looks like some directed
troubleshooting...
Also.. onetime I think we had aproblem... we rebooted our server from where the
NFS mounts were donewhich helped.

Brian,
Yes we canwrite 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 saysit's
creating the archive log, but nothing shows up and the db justhangs.

Yes we are... and noproblems.
One weapon we are findinguseful is the 10G OEM.. does server parameter
comparisons...ie..did theghost admin change something..? Even when we catch
them.. it slides likewater 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
canaccommodate issue (forget the details now.. something about async). Iwould
do some testing..can you copy files there, write there ...have theAdmin check
the syslog and so on..
