Logical Drive
A logical drive is a partition in a physical array of disks
that is made up of contiguous data segments on the
physical disks. A logical drive can consist of any of the
following:
• an entire physical array,
• more than one entire physical array,
• a part of an array,
• parts of more than one array, or
• a combination of any two of the above conditions.
Hot Swap
A hot swap is the manual replacement of a defective
physical disk unit while the computer is still running. When
a new drive has been installed, you must issue a command
to rebuild the drive.
