Use this page to select the storage disk that you want to use as the repository for the new cluster.
This page provides a list of all discovered and available storage disks on the controlling node that are shared among all other nodes in the cluster. The storage disks that are available for you to select are based on the nodes that you selected to include in the cluster.
The disk or disks that you select are dedicated for use exclusively for the cluster repository. PowerHA® SystemMirror uses this repository for clusterwide name space management and internode synchronization. Additionally, the repository stores configuration information for the cluster and the nodes within it, including security settings for cluster communications.
This page provides either a single table of shared disks or, for a multiple-site configuration for a linked cluster, two tables, one for each site.
If you are creating a cluster without sites or a multiple site configuration with a stretched cluster, select a single storage disk for the cluster repository.
If you are creating a multiple site configuration with a linked cluster, you must select a storage disk to be the cluster repository on each site.
The default selection for a table is the storage disk that has the smallest amount of available space. A repository disk must be at least 512 - 460,000 MB in size.
