C.2.5 Reconstructing an Array

.The Galaxy 65 Subsystem automatically reconstructs redundant arrays (RAID 3, RAID 4, RAID 5, RAID 50, and mirrored) if an array becomes critical and a properly sized spare drive is available. An array becomes critical when one or more member drives fail.

If a reconstruct does not start automatically, it means that no valid spares are available. To start a reconstruct, replace the failed drive, and add the new drive as a dedicated spare (see E.1.1, ”Adding a Dedicated Spare”, on page 168 and E.2, ”Enabling Dynamic Spares”, on page 169) or as a pool spare (see E.3.1, ”Adding a Spare to the Spare Pool”, on page 171). Remember that any pool spares added might be used by any critical array, not necessarily the array you want.

C.2.6 Expanding Array Capacity

You can expand array capacity without stopping I/O activity, so you can continue using the array while the expansion process runs. You can only expand one array at a time.

Notes	1	Expanding an array here does not change the size of the host operating system partitions
		that reside on the array, because the RAID controller is working at the block level not the
		file system level of the operating system. To use the new space, you must create a new
		operating system partition using the newly added space or use a third-party application
		specific to the operating system to change the partition size.
	2	How you create a new partition or resize an existing one depends upon the operating
		system. Most operating systems cannot resize an existing partition. Refer to your
		operating system documentation.
