File used to maintain information about prior controller activities
or errors.
event notification
Process for transmitting events.
F
failed
State of a non
redundant
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.
failed partition
A
partition
that is no longer usable by an array because it is either
logically bad and therefore no longer needed, or physically
damaged.

.
fault-tolerant array
Refers to an array that can continue to function after a disk drive
failure without loss of data. See also
redundant
.

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