Inconsistent clustering

[Phil]

I have 2 servers in a Win 2000 cluster (Active/Passive)
controlling access to shared drives on an HP MSA1000 disk
array. For end users, access to the shared disks is via
the cluster name/ip address and so users are able to
access the shared disks in the same way no matter which
Server is Active.
Without clustering in place windows has issues with files
on the shared drives and can give out a corruption error
message when the files are accessed.

I have 2 shared drives on the disk array, Q: and R:. Each
is on its own disk volume . However I am seeing different
handling of these drives which I cannot explain.
R: drive is only accessible as a local drive from the
server which is currently Active and the corresponding
disk volume can only be seen in the Disk Management tool
from the Active node.
Q: drive on the other hand is accessible from both the
Active and passive servers of the cluster and its volume
is visible in the Disk Management tool of both servers.

I am unable to use Q: drive safely as it is and risk
encountering corruptions.

Any ideas ?

sounds like something is not configured right
you should not be able to see any of the cluster drives from both nodes
locally. the passive node should not show any of the cluster resources as
being local (especially in disk management)

Yep, that sounds about right, but everything looks OK.

I did find article 275704 which sort of fits the bill, but
we are currently on SP4 so this bug should be fixed OK.

yeah...that's the keyword - 'should'
i have had many issues in the past where msft says it is fixed in a service
pack that i'm already running and still have the problem

Phil,

The node that own the Quorum disk (Q:\) should be the only node that can
access that drive and see it in Disk Management.

Since that's not what is occurring in your case because both nodes can
access Q:\ drive and see it in Disk Management, then I would consult with
your storage vendor to figure out if it's a problem with the controllers or
if it's a problem with multi-path I/O software if it's installed.
