Shared storage pools

On the Virtual I/O Server (VIOS) Version 2.2.0.11, Fix Pack 24, Service Pack 1, and later, you can create shared storage pools. Shared storage pools provide distributed storage access to all VIOS logical partitions in a cluster.

On the VIOS Version 2.2.0.11, Fix Pack 24, Service Pack 1, you can create a cluster that consists of only one VIOS partition that is connected to the same shared storage pool. On VIOS Version 2.2.1.3, or later, you can create a cluster that consists of up to four networked VIOS partitions. On VIOS Version 2.2.2.0, or later, a cluster consists of up to 16 networked VIOS partitions. Thus, a cluster consists of up to 16 VIOS logical partitions with a shared storage pool that provides distributed storage access to the VIOS logical partitions in the cluster. Each cluster requires a separate repository disk and shared storage pool disks. The shared storage pool can be accessed by all the VIOS logical partitions in the cluster. All the VIOS logical partitions within a cluster must have access to all the physical volumes in a shared storage pool.
