Host System

Any system on which the RAID controller is installed. Mainframes, workstations, and personal systems can all be considered host systems.

Hot Spare

An idle, powered on, stand-by physical disk ready for immediate use in case of disk failure. It does not contain any user data. A hot spare can be dedicated to a single redundant virtual disk or it can be part of the global hot-spare pool for all virtual disks controlled by the controller.

When a disk fails, the controllers' firmware automatically replaces and rebuilds the data from the failed physical disk to the hot spare. Data can be rebuilt only from virtual disks with redundancy (RAID levels 1, 5, 10, or 50; not RAID 0), and the hot spare must have sufficient capacity.

If the hot spare is designated as having enclosure affinity, it attempts to rebuild any failed disks on the backplane within which it resides prior to rebuilding any other on other backplanes.

Hot Swap

Replacement of a failed component while the system is running and operating normally.

I

Initialization

The process of writing zeros to the data fields of a virtual disk and, in fault tolerant RAID levels, generating the corresponding parity to put the virtual disk in a Ready state. Initializing erases previous data and generates parity so that the virtual disk passes a consistency check. Virtual disks can work without initializing, but they can fail a consistency check because the parity fields have not been generated.
