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
.
L
legacy disk
Disk that contained a valid partition table when connected to the controller. The controller manages the
disk as a legacy disk array where there is a one-to-one logical-to-physical mapping of array to disk.
logical device
Volume comprised of space from one or more physical drives and presented to the operating system as if it
were a single storage unit.
M
monitoring
Process of receiving, displaying, and logging system events.
P
partition
A section of a disk storage device created by the operating system disk management program, in which data
and/or software programs are stored. Computers have a primary operating system partition that contains
the special files needed to boot the computer. Each operating system partition is assigned a unique drive
letter, such as C or D. A single disk device can have multiple partitions.
phantom object
Object that represents a component that cannot be configured by the controller management software; for
example, a missing drive.
R
rescan
Process of updating the current screen to show all currently available resources.
S
Serial Attached SCSI (SAS)
An evolution of parallel SCSI to a point-to-point serial interface
Serial ATA (SATA)
A successor to ATA that uses a serial, instead of parallel, interface.
signature
The area on each disk reserved for use by the SATA/SAS controller.
