Remove disk from windows 2008 cluster

But what happens when you cannot figure out what command syntax is needed? Well PowerShell has all the help documentation built into the PowerShell utility itself and even includes examples. Please refer to this in-box help when you use PowerShell. This is also an area where we would like your feedback — please let us know if there is anything which you cannot find or you believe was misleading.

Make a new disk available for use in a failover cluster. The disk LUN must be exposed to all nodes in the failover cluster, and should not be exposed to any other servers. When adding a disk, make sure that the configuration of the storage allows the operating system to recognize and mount the disk as needed.

The disk must be a basic disk not a dynamic disk and should not be exposed to servers outside the cluster. The cmdlet Get-ClusterAvailableDisk gets information about disks that you can add to the cluster. Quorum disk is the first resource brought online when cluster service attempts to form a cluster.

When the cluster service on the forming node starts, it first tries to bring online the physical device designated as quorum disk. It executes the disk arbitration algorithm on the quorum disk to gain ownership.

On successful arbitration, cluster service sends a request to clusdisk to start sending periodic reserves to the disk to maintain ownership. Then cluster service sends a request to clusdisk to unblock access to the quorum disk and mounts the volumes on the disk.

Successful mounting of the volume s , completes the online procedure and the cluster service then continues with the cluster form process. The request is passed from the cluster disk driver to the Microsoft storage driver stack and finally to the driver specific to the HBA that communicates to the disks. It may also be passed to any multipath software running in the storage stack.

Once the disk has passed all of these tests, the disk resource is marked as online and the cluster service then continues to bring all other resources online. Each node in the cluster renews reservations for any LUNs it owns every three seconds.

If the nodes of a cluster lose network communication with each other for example, if there is no communication over the private or public network , the nodes begin a process known as arbitration to determine ownership of the quorum disk. The node that wins ownership of the quorum disk resources in total communication loss between cluster node will remain functional. Any nodes that cannot communicate and cannot maintain or acquire ownership of the quorum disk will terminate the cluster service and any resources that node was hosting will be moved to another node in the cluster.

The node that currently owns the quorum disk is the defending node. The defender assumes that it is defending against any cluster nodes that it cannot communicate with and for which it did not receive a shutdown notification.

Thank you. Removes a volume from the Cluster Shared Volumes in a failover cluster, and places it in Available Storage in the cluster. After placing a volume in Available Storage, you can use the volume when you configure a new clustered role. Specifies the name of the cluster on which to run this cmdlet.
