HSxxx Client
Provides the HSxxx Storage window for storage connected to
the HSxxx controller.
initialization
For subsystems, the process of restarting the controllers and
reestablishing the subsystem’s configuration and operation; that
is, bootstrapping the subsystem. For virtual disks, the process
of writing the controller's file structure to the virtual disk
member devices. On the member disks, the file structure is
represented by metadata.
JBOD (Just a Bunch of
Disks)
JBOD is an industry term for a single-device virtual disk. A
JBOD virtual disk does not provide any level of data
redundancy.
known client list
See client list .
Local Area Network
(LAN)
A network that is confined to a single geographic location.
local connection
A direct hardware connection from the Client to a single
subsystem using either of two methods:
■ A connection from a standalone computer running the
Client to the serial maintenance port on the controller
■ A connection from a host system running the Client to a
subsystem on the host's SCSI bus
A local connection enables you to connect the Client to one
subsystem controller within the physical range of the serial or
host SCSI cable.
logical drive
See virtual disk .
logical storage unit
See virtual disk .
Logical Unit Number
(LUN)
A SCSI bus supports a number of target devices, each of which
has a number of logical units. A logical unit number is a logical
unit's address on a target. A controller maps one or more SCSI
logical units to a virtual disk that the host can access. “LUN” is
also used to refer to the virtual disk itself.
mapping
The internal controller process of organizing single or grouped
devices into virtual storage units (that is, virtual disks).
