Adding SFW support to the cluster

Use the following procedure to add SFW support to the cluster.
To add SFW support to the cluster
  1. With the active node of the cluster on Server B, use Add/Remove Programs on Server A to add the Microsoft clustering and DMP options to SFW on that server and reboot. Then move the cluster resources back to server A. Server A is now the active node.
    Note: If you reboot a server that has the active node of the cluster, it will fail over to the other node. You have more control of the situation by moving the resources to the other node before doing a reboot.
  2. On Server B, install InfoScale Storage with the DSMs and Microsoft clustering options and reboot.
  3. On Server A, which is now the active node of the cluster, use SFW to create a dynamic cluster disk group that will be used for the dynamic quorum. The disk group should contain three disks, and the disk size is recommended to be 500 MB. You need to create a three-way mirrored volume on the three disks with SFW. You can also use two disks, but three disks provide added redundancy.
  4. Change the existing regular SFW dynamic disk groups on Server A to cluster disk groups.
A regular dynamic disk group is converted to a cluster disk group through the command line by using the command to import a disk group, vxdg import, with the -s option, the option that does the conversion. You will need to deport the disk groups first before you can import them. You can deport them through the GUI Deport Dynamic Disk Group command.
