Disk Arrays
A disk array is a collection of physical drives in a RAID. Logical drives are made
from disk arrays. The Disk Arrays–Information tab displays a list of disk arrays
along with their status and capacity:
• Device ID – This is the unique ID number assigned to an individual disk array
• Alias – A user-specified name for the disk array
• Status – This refers to functional status of this disk array. OK is normal
• Configurable Capacity – This is the data storage capacity available for new
and existing logical drives
• Free Capacity – This is the data storage capacity available for new logical
drives
To see more information about a specific disk array, click on its Device ID link.
To access the Disk Arrays–Information tab:
1. Click the Subsystem icon in Tree View.
2. Click on the Disk Arrays icon.

spare assigned to this disk array. A hot spare drive is created for all
RAID levels except RAID 0, when five or more unconfigured physical
drives are available
