Requirements When Configuring Network Appliance NAS Devices as Quorum Devices

The administrator has the option of deciding whether to use the Network Appliance NAS device as a quorum device.

When you use a Network Appliance NAS device as a quorum device, you must meet the following requirements.

• You must install the iSCSI license from Network Appliance.

• You must configure an iSCSI LUN on the Network Appliance NAS device for use as the quorum device.

• When booting the cluster, you must always boot the Network Appliance NAS device before you boot the cluster nodes.

  If you boot devices in the wrong order, your nodes cannot find the quorum device. If a node should fail in this situation, your cluster might be unable to remain in service. If the cluster fails because the Network Appliance NAS quorum device was not available, bring up the NAS device. After that action completes, boot the cluster.
