Data and Device Mappings changed

Hello Everyone,

I am having a very strange issue and am hoping someone has seen this before:

I have a win 2k3 ENT sp1 64bit cluster with an EMC back end. Each node has
mulitple HBA's, multiple paths to the back end.

It appears that 2 of my drives at the device level have swapped.
ex: drive T contains sql log A = EMC device 123
drive N contains sql log B = EMC device 456

I'm not sure if it was during a reboot or when/where it happend, but now the
configuration is
drive T contains sql log A = EMC device 456
drive N contains sql log B = EMC device 123

SQL didn't complain because the drive letters and associated data remained
the same, but this played havoc on our replication - which is how we
discovered the issue.

I find it highly unlikely that a DBA would have changed the drive letter and
swapped the data in Windows. Unfortunately the logs don't show anything.
That is why I am suspecting that it is possibly the cluster sw?

Sorry if the explanation is confusing...

Thanks in advance!!!!
