Step 1: Mapping the cluster

If you have a clustered system and want to set up a mirrored cluster using synchronous mirroring, you must do the following:

Determine what volumes you currently have.
Determine where each volume is located.
Determine the size of each volume you want to mirror.
Determine how you will structure your data on the new system by sketching a structure of how the data will look, after you begin storing information on your new cluster.

To map your existing cluster, complete the following steps.

Step	Action
1	List all volumes you have on the local node by entering the following command: vol status -r Result All volumes and spare disks are listed.
2	Determine the size of each volume by entering the following command: vol status -b Result The command displays the block size of the volume (in bytes), the RAID volume size, and the WAFL® file system size.
3	Note the size and name of the volumes you want to mirror.
4	Repeat Steps 1 through 3 for the partner node.
5	Go to Step 2: Determining your storage requirements.
