Fault/Service Required
If the Fault/Service Required yellow LED is illuminated, the module has not gone
online and likely failed its self-test. Try to put the module online (see "Shutting
Down a Controller Module" on page 84) or check for errors that were generated in
the event log from RAIDar.
Boot Handshake Error
When powering on the controllers, if RAIDar or the event log report a boot
handshake error, power off the enclosure for two seconds and then power it on
again. If this does not correct the error, remove and replace each controller as
described in "Removing a Controller Module or Expansion Module" on page 85.
Setting the Internal Clock
The clock battery is not a FRU. You must send in the controller module for service
to have the battery replaced.
When the serviced controller module is reinserted into the enclosure, the
controller's date and time are automatically updated to match the date and time of
the partner controller.
In a single controller configuration, you must set the clock manually. To set the date
and time in RAIDar, select Manage > General Config > Set Date/Time.
Persistent IP Address
The IP address for each controller is stored in a SEEPROM on the midplane. The IP
address is persistent. When you replace a controller, the new controller will have the
same IP address as the old controller.
Moving a Set of Expansion Modules
The enclosure ID for the RAID controller is always zero. The expansion modules
are then numbered from one to four. The number is visible on the front on the
enclosure. If you move a single expansion module, or a set of expansion modules to
another controller and reconnect them in a different order, it is likely that the
enclosures will not be numbered in sequential order. If the enclosure IDs do not
update correctly or are incorrectly ordered, use RAIDar to force the controller to
