When you expand an array, you add free space at the end of the array
(Figure 117)
. For more information about expanding an array, see
section D.2.6 page 228 .
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.
D.3.2 Viewing Partition Status Information
You can perform three functions related to partition status information:
• View partition status (see page 237 )
• View partition statistics (see page 239 )
• Reset partition statistics (see page 241 )
D.3.2.1 Viewing Partition Status
You can view the status of a partition, including the following
information:
• A rray 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 EF2800 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).
• Percentage of total array: The percentage of the total array that this
partition represents.
