Hi All
We have an oracle Database mounted on an E4500. We then have 2 filers
Filer A has volumes
/vol/u01 /vol/u02 /vol/u03
Filer B has volumes
/vol/u04 /vol/u05 /vol/u06
All volumes are mounted on this one E4500, but what we have expereienced is that from filer A, the /vol/u01 mount point UNMOUNTS periodically. About 10 times a day. Yet the rest of the volumes dont.
Has anyone experienced this?
THanks KEVIN

You're not using automounter are you? These should be permanent NFS mounts defined in your /etc/vfstab. Even with automounter, assuming Oracle is actually running, Solaris tends not to umount filesystems with open files on them. I'm guessing your Oracle binaries and config files are in /u01/app/oracle/product/etc, etc. and so the loss of that filesystem pretty much means your database has to be shut down first.
MessageHi Kevin:
You may want to check into the firmware revision you are running on your switches. We ran into similar problems, but by updating firmware on the switches we were able to solve the problems.
Please contact our engineering department if you would like some specifics on what we have found with different switch and Nic card combinations.
