Hi All,

So the situation is... I am using Hyper-V and I had a failover cluster [FOC] working very hapily for approximately 12 months now.

Friday... Bang all of a sudden it stops working all the storage can not be brought online within the FOC Manager.

I have the storage from the servers currently mounted via iSCSI to individual server and I have the servers up and running in standard Hyper-V. Soo the storage is good.

I have created a test lun and I am trying to bring the storage online as the witnes drive. Still failing with an all new lun :(

After some serious time on google there is a few things that I have attempted with little result. here is where I ask the fine people at experts exchange for some assistance.

I have attached the log files from the cluster, any help is appreciated.

Regards,

Daniel.

Hi,

I have looked into this and whilst the solution is confusing did not appear to fix my issue.

Any further suggestions are appreciated.

When you create a LUN, and connect to it via the iSCSI initiator, are you able to mount the volume on a host and then add it to cluster disks?

Hi,

I can add the volume to a host and utilise the storage. This is how I have managed to bring the servers that were on the Cluster online in HyperV.

I have the issue when I attempt to attach the storage via the iSCSI initiator on both hosts and attach the storage to the failover cluster.

I get the attached error.

Daniel

Further to my last post, I have tried to evict individual nodes out of the cluster to eliminate if there is one of the nodes causing the issue and unfortunately that is not the case.

Adding the disk in the FOC Manager still fails on each of the nodes.

:(

Daniel

try running the cluster validation report and see what it comes up with for storage issues. It sounds like there is an issue in cluster config itself. also, are you runinng hyper v or R2? and what is the OS on the servers?

Obviously the first question should be what has changed recently...  Also, what iSCSI target software are you using?  It the iSCSI LUN configured for clustering?
