Storage partitioning is a base feature of the . A is a logical entity that uses one or more that can be accessed by a single host. It can also be shared among hosts that are part of a host group. The first time you map a volume to a specific host or host group, a storage partition is made. Subsequent volume mappings to that host or host group do not make another storage partition.
Do not use more than one storage partition under these conditions:
You have only one attached host that accesses all of the volumes in the storage array.
You prepare to have all attached hosts share access to all volumes on the storage array. When you use this type of configuration, all of the hosts must have the same operating system. You also must have special software on the hosts (such as clustering software) to manage volume sharing and accessibility.
