Defining a Partition
Partitions are expressed as a percentage of the storageset or single disk unit that
contains them:
• Mirrorsets and single disk units—the controller allocates the largest whole
number of blocks that are equal to or less than the percentage you specify.
• RAIDsets and stripesets—the controller allocates the largest whole number of
stripes that are less than or equal to the percentage you specify.
— Stripesets—the stripe size = chunk size × number of members.
— RAIDsets—the stripe size = chunk size × (number of members minus 1)
An unpartitioned storage unit has more capacity than a partition that uses the whole
unit because each partition requires a small amount of disk space for metadata.
Guidelines for Partitioning Storagesets and Disk Drives
Keep these points in mind when planning partitions for storagesets and disks:
• Each storageset or disk drive may have up to eight partitions.
• In transparent failover mode, all partitions of a particular container must be on the
same host port. Partitions cannot be split across host ports.
• In multiple-bus failover mode, all the partitions of a particular container must be
on the same controller. Partitions cannot be split across controllers.
• Partitions cannot be combined into storagesets. For example, you cannot divide a
disk drive into three partitions, then combine those partitions into a RAIDset.
• Just as with storagesets, you do not have to assign unit numbers to partitions until
you are ready to use them.
• The CLONE utility cannot be used with partitioned mirrorsets or partitioned
stripesets. (See “Creating Clones for Backup,” page 7–2 for details about cloning.)
Changing Characteristics through Switches
CLI command switches allow the user another level of command options. There are
three types of switches that modify the storageset and unit characteristics:
• Storageset switches
• Initialization switches
• Unit switches
