Hi,

we could reproduce that issue with the iSCSI initiator service, so we opend
a case with Microsoft on Thursday.
After some investigation, they solved our Problem with this:

Did your storage pass all cluster validation tests for the storage?

Hi John,

the whole cluster passed the validation test.

Do you have the dependencies setup so that R:\MOUNTPOINT depends on Disk R:
in the cluster?

My colleague (he is also responsible for the storage system) created the
disks and attached them to the cluster.
Unfortunately he does not know anything about cluster requirements like
dependency for resources, and i cannot say if the dependency where set
propperly bevor he tried a failover.

Does the same issue occur if you drop down to a single path without MPIO
software?

I will check that on monday.

Thanks for your help.

Regards,

Uwe

Hi,

I need your help with a 2-node Cluster.
The cluster is build of 2 Windows 2008 nodes connecting to their shard
Disks
via Fibre Channel to our Netapp Filer.
My instance consists of disk R:\ and a mount point R:\MOUNTPOINT
We installed a SQL2005 Server on this Disk R:\ and the Transaction Logs on
the mount point.

From now on, any file system operation (copy, change of user rights)
results
in a failure of the mount point disk. The disk changes to failed, execute
an
chkdsk and goes back online.
After a minute or two, it repeats this over and over again.
If I format this disk and bring it as S:\ into this Instance, I can do
whatever I want on the filesystem an nothing goes wrong.

I tried this on several instance with different disks and can reproduce
this
behavior.

Installed software: SQL2005, Netapp MPIO, Fujitsu-Siemens Serverview

Any suggestions on this strange problem?

Cheers,

Uwe
