Recovering NEC Clusters › Disaster Recovery Considerations

Disaster Recovery Considerations

You should consider the following information when protecting NEC clusters:

• We do not recommend that you use partial shared disk configuration, in which some disks are owned by one node and some disks are owned by another node.
• To avoid complications when matching disks, shared disks should be the last disks and should have the highest number when viewed from Administrative Tools, Computer Management, Disk Management.
• You can configure disaster recovery information to be saved to an alternate location on a different machine to further protect disaster recovery information
• You must back up the local disk of each cluster node with a physical hostname and shared disks with the virtual computer name (switched disk, cluster disk, or shared disk).
