Re: Physical disk hangs at "offline pending"

Hi,

We have installed Oracle failsafe on this cluster and the drive in question
is part of the "Cluster Group" set of resources. The oracle database resides
on this SAN drive. I have stopped all oracle services on the server giving me
the problems and the disk still does not go offline to enable a failover
unless the server is shut down.
I suppose there must be something else preventing the failover and am trying
to determine what could be preventing this disk from being released. The
server in question does have exclusive rights to this physical disk when it
is the active member.
If anyone has any idea as to how I might determine if some process is
refusing to release it's resources please make a suggestion.
Is there a way to increase the logging level of the cluster and should that
give me a better indication of what may be the problem? (the logs are fairly
hard to decipher even at the default logging level).

Thanks in Advance,

Sounds like something has a handle to the drive that is preventing cluster

Hi,

I have a 2 node cluster that works correctly when the active server goes
down.
All resources are taken over by the passive member.

When I try to move resources from node 1 to node 2 everything works fine
as
well.
The problem is that when I try to move the the resources back to the
original node all resources move except for one physical disk. This
physical
disk status remains as "offline pending". The cluster log contains many
entries similar to what follows:
"FmpofflineResource: offline resource <drivex>returned pending"
until finally
"RmpTimerThread: Resource drivex pending timed out, CP 3 - seting state to
failed."

The only way for us to get the offline resource available for the other
cluster member is to reboot the server that failed to put the physical
drive
offline.

Any ideas would be appreciated.
