Maintaining Your Cluster 51

Maintaining Your Cluster

The following sections describe two common cluster maintenance issues, how

to replace a quorum disk that has failed and how to remove a node from your

Dell™ PowerVault™ NX1950 cluster solution.

Replacing the Quorum Resource

If access to the shared quorum resource fails or if the Dell|Equallogic PS

Series volume associated with the quorum resource fails, the cluster crashes.

Although the cluster service attempts multiple restarts, the cluster does not

respond until the resource is replaced.

You can replace a failed quorum disk using the following procedure:

In the PS Series group, create a new volume for the quorum resource.

Apply the same access control record settings as for the failed quorum

volume. For more information, see "Configuring Volumes in a PS Series

Storage Array" on page 22.

On each cluster node, set the cluster service to

manual

to prevent

repetitive restarts.

On the first node (Node A), use the iSCSI initiator to log in to the new

quorum volume. Ensure that you make the connection persistent and to

bind the connection. For more information, see "Connecting Nodes to

Volumes" on page 29.

Align the disk sectors, as described in "Aligning the Disk Sectors" on

page 32, and configure as a basic disk, as described in "Configuring a Basic

Disk" on page 32.

On Node A, using the

Disk Management

utility, create a single NTFS

partition on the new quorum disk and assign a different drive letter from

that of the original quorum resource. For more information, see "Assigning

a Drive Letter and Formatting a Partition" on page 32.

On Node A, open a command prompt and start the cluster service in

fixquorum mode, using the net start command:

clussvc /fixquorum
