Glossary 97

disk ID

Unique disk identifier that consists of the channel number, SATA ID. For example, (channel:ID:LUN) 1:04:0. See channel.

drive LED

Disk indicator LED that illuminates during read or write operations.

E

event

Notification or alert from the system, indicating that a change has occurred.

event log

File used to maintain information about prior controller activities or errors.

event notification

Process for transmitting events.

F

failed

State of a nonredundant array that has suffered a single drive failure, or a redundant array that has suffered multiple drive failures. A failed array is inaccessible and data is lost.

fault-tolerant array

Refers to an array that can continue to function after a disk drive failure without loss of data. Fault tolerant, or redundant arrays, include RAID 1 arrays. See redundant.

foreign disk

Disk that has previously been configured on another Adaptec RAID controller. The RAID signature on the disk allows the RAID controller to identify whether or not the disk was configured on the controller it is currently connected to.

H

hard disk drive

Basic unit of nonvolatile, nonremovable, magnetic storage media. See disk.

hot spare

A spare hard disk that automatically replaces a failed hard disk on any array associated with any HBA.

hot swap

To remove a component from a system, and install a new component while the power is on and the system is running.

I

impacted

An impacted array is one which has been created but for some reason the initial build operation did not complete. All member drives are present and operational, and all data written to the array is protected. To optimize the array, run a Verify with Fix Task.

initialize

See configure.
