116 Software Installation and User’s Guide
ICP RAID Console
During boot up, the system displays the updated firmware version. You can also relaunch
ICPCON and select the applicable ICP RAID controller to view its new firmware version
at the bottom of the console (for example, FW:2.32.00-Rxxx).
10.5.1.3 Intelligent Fault Bus
To access this menu option, from the Advanced Setup menu, select the Configure
Controller option and press Enter to display the Configure Controller menu, then select
the Intelligent Fault Bus option and press Enter.
Intelligent fault bus is a standard for enclosure management that was popular with SE
(Single Ended) SCSI but is no longer supported with current LVDS (Low Voltage
Differential Signaling) SCSI or SATA enclosures. So this option is no longer available.
Today’s modern subsystems are using SCSI Accessed Fault-Tolerant Enclosures (SAF-
TE) as communication links to the controller. These intelligent subsystems are normally
built on so-called backplanes, which host hard disks equipped with Single Connector
Attachment (SCA) connectors. The backplane has dedicated electronics with
microprocessor and firmware which allows intelligent communication between the
subsystem/backplane and the ICP RAID controller. Through this channel the subsystem
can report its temperature and the power supply status to the ICP RAID controller. The
major objective of SAF-TE is
auto hot plug . In contrast to hot plug , auto hot plug allows a
defective drive to be simply removed from the subsystem and the replacement unit
installed in its place. Both the ICP RAID controller and the subsystem control this process
so that problems on the SCSI bus are eliminated and the rebuilding of the missing data is
initiated automatically. No further user interaction is necessary.
10.5.1.4 Non-Intelligent Enclosures
To access this menu option, from the Advanced Setup menu, select the Configure
Controller option and press Enter to display the Configure Controller menu, then select
the Non-Intelligent Enclosures option and press Enter to display the Select Enclosure
screen ( Figure 10-61 ).
Since SAF-TE subsystems are expensive, the ICP RAID controller integrates
functionality which allows for the control of up to 16 non-intelligent enclosures with up to
15 hard disks each, and provides for auto hot plug.
In the example in Figure 10-61 , one subsystem is defined. The hard disks with their disk
shuttles could also be mounted directly into the server enclosure. The term enclosure in
this case is a definition set, which includes all hard disks which should be auto hot
pluggable.
