Guidelines for Partitioning Storagesets and Disk Drives
Keep these points in mind as you plan your partitions:
n You can create up to eight partitions per storageset or disk drive.
n All of the partitions on the same storageset or disk drive must be
addressed through the same controller port. This ensures a
transparent failover of devices should one of the dual-redundant
controllers fail.
n Partitions cannot be combined into storagesets. For example, you
cannot divide a disk drive into three partitions, then combine those
partitions into a RAIDset.
n Partitioned storagesets cannot function in multiple bus failover
dual-redundant configurations. Because they are not supported, you
must delete your partitions before configuring the controllers for
multiple bus failover.
n Once you partition a container, you cannot unpartition it without
reinitializing the container.
n Just as with storagesets, you do not have to assign unit numbers to
partitions until you are ready to use them.
