NOTE:
Front Panel View of Controller Failure
What will happen when one of the controllers fails?
Should one of the controllers fail, the existing controller will
automatically take over within a few seconds.
The red ATTEN LED will light up, and the
message "Redundant Ctlr Failure
Detected" will appear on the LCD. Users
will be notified by audible alarm.
• Although the existing controller will keep the system working. You should contact
your system vendor for a replacement controller as soon as possible. Your vendor
should be able to provide the appropriate replacement unit.
• Some operating systems (SCO, UnixWare, and OpenServer, for example) will not
retry accessing the hard disk drives while controller is taking over.
When and how is the failed controller replaced?
Remove the failed controller after the "working" controller has taken
over. For a controller with hot-plug capability, all you have to do is to
remove front panel and pull out the eject levers to remove the failed
controller.
The new controller has to be pre-configured as the "Secondary
Controller." (The replacement controller provided by your supplier
should have been configured as the Secondary controller. It is
recommended to safety check the status of the replacement controller
before installing it to your redundant system. Simply attach power to
the replacement and configure it as "Secondary." When safety check
is done, remove the failed controller and install the replacement
controller into its place.)
When the replacement is connected, the "Auto-Failback" will start
automatically (IFT-3102U2G and above). If the replacement controller
does not initialize, execute the following steps for the new controller
to function. Press [ENT] for 2 seconds on the existing controller to
enter the main menu.
Use ▼ or ▲ to choose "View and Edit
Peripheral Dev..," then press [ENT].
Choose "Set Peripheral Device Entry..,"
then press [ENT].
