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:
1 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.
2 On each cluster node, set the cluster service to
manual to prevent
repetitive restarts.
3 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.
4 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.
5 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.
6 On Node A, open a command prompt and start the cluster service in
fixquorum mode, using the net start command:
clussvc /fixquorum
