You can only expand a partition into contiguous, following, free space. In Figure 3–2 , you can expand
partition 1 or you can create additional partitions in the free space.
After you partition all of the free space, you can expand the size of a partition only by deleting a partition
that follows (has a higher number than) the one you want to expand. In
Figure 3–3 , you can delete
partition 3 and then expand partition 2 to use some or all of partition 3’s space.

Caution If you delete a partition, you also delete all data stored in the partition. Be sure that you back up all data
before deleting a partition.
When you expand an array, you add free space at the end of the array as shown in Figure 3–4 . For more
information about expanding an array, see C.2.6, ”Expanding Array Capacity”, on page 126 .

After expanding an array, you can either add a partition or expand the last partition to use the new free
space. You can also delete one or more partitions and expand a partition into the space.
C.3.2 Viewing Partition Status Information
You can perform three functions related to partition status information:
• View partition status (see page 134 )
• View partition statistics (see page 136 )
• Reset partition statistics (see page 138 )
C.3.2.1 Viewing Partition Status
You can view the status of a partition, including the following information:
• Array state: Online, Offline, Critical, or Fault-tolerant.
• Array type: RAID level (0, 3, 4, 5, 50, Volume, or Mirrored). The term “mirrored” is used for both RAID
1 and RAID 10 arrays.
• Array drives: Number of drives in the array when fault-tolerant. For example, if a three-drive RAID 5
array loses one drive, the number will still display 3.
• Name: Name you give to the partition.
• Serial number: Unique number the Galaxy 65 Subsystem assigns to each partition.
• Target ID:LUN: Target ID and LUN presented to the host system.
• Partition size: Size of the partition (expressed in MB).
