Glossary
SCSI bus
A SCSI bus provides a means of transferring data between SCSI
devices. A SCSI bus is either an 8- or 16-bit bus that supports up to
8 or 16 devices, including itself. The bus can consist of any mix of
initiators and targets, with the requirement that at least one
initiator and one target must be present.
SCSI device
A SCSI device is a single unit on a SCSI bus that originates or
services SCSI commands. A SCSI device is identified by a unique
SCSI address. SCSI devices can act as initiators or targets.
SCSI port
A SCSI port is an opening at the back of a router that provides
connection between the SCSI adapter and SCSI bus.
slot
A receptacle in an enclosure for inserting and removing a SCSI
device.
spin-up
Disk drives operate at a specific speed, for instance 10,000 rotations
per minute. When power is applied to a disk drive, it
spins up
(starts spinning and spins at increasing speeds) to reach this final
operating speed.
stand-alone
Stand-alone mode is when only one controller is used in an
external subsystem.
U
unkill
In active-active mode, when a surviving controller removes the
reset from the other controller, it unkills it. The other controller will
reboot and attempt to come online.
