Not able to Bring disk online

Question

_{Wednesday, July 13, 2016 8:48 PM}

I have a cluster that server 2 which is using iscsi was disconnected by mistake. It was reconnected but I'm not able to bring the drives online. 

I get and error from Virtual Disk Manager

The specified disk or volume is managed by the microsoft failover cluster component. The disk must be in the cluster maintenance mode and the cluster resource status must be online to perform this operation.

Cluster Disk 1 (Disk Witness in Quorum) Cluster Disk 2 (Cluster Shared Volumes) and CSVLUN1 are now all offline in my Disk management. 

I put the CSVLUN1 in maintenance mode, but don't know where to set the cluster status to online...

Hi,

If a disk is added to cluster, it would show as reserved on the node. And it could not be brought online on the node. It is normal behavior.

How are the disks showing in failover cluster? If not correct, I suggest you remove them from cluster, and then add them back again.

Best Regards,

Leo

What you are showing in your screen capture is normal behavior.  Unless a disk is defined as a Cluster Shared Volume (CSV), ownership, i.e. ability to bring online, within the cluster is restricted to one node at a time.  A volume is 'owned' by a single node of the cluster and controls all read/write access to that volume.  You can change the ownership of the volume to a different node of the cluster, and it will then appear online on the new owning node and Reserved on the other node(s) of the cluster.

Leo,

Thanks for the reply. The disk show online in the Failover Cluster Manager and owned by DXBL1 Node. DXBL2 isn't able to bring the disk online. Do I remove them from disk manager first ? The DXBL1 Node is up and working with all the guest on them.

Would removing the DXBL2 Node from cluster work and re-add it so that I can regain access to the reserved drives?
