Installing a SCSI Controller Module
1. Keep the array powered on. Gently slide the controller module into the unit until
it clicks and is seated in the backplane.
Caution –
Be sure that the module is properly inserted into the guide rails of the
array.
2. Turn the thumbscrews on the left and right sides of the controller module
clockwise until they are finger-tight, to secure the module and to make the
module’s front panel flush with the chassis.
Note –
To ensure that a thumbscrew is finger-tight, tighten it with a screwdriver
and then loosen the thumbscrew counterclockwise a quarter-turn.
The new controller automatically becomes the secondary controller.
Caution –
Wait a minimum of 10 minutes for the firmware synchronization process
to be completed. If the newly installed controller is removed for ANY reason during
the period when the status LED is AMBER (for 10 minutes or more), the controller
can be rendered inoperable and must be returned for repair.
In a redundant controller configuration where a new controller FRU is installed, the
controller status LED will remain AMBER until the controllers complete the
redundant controller process which can take more than 10 minutes. Identical
firmware versions on both controllers is required for proper redundant controller
operation.
The redundant controller process automatically synchronizes the firmware version
of the newly installed controller FRU to match the firmware version of the other
running controller. For example, if the running controller has firmware 3.25P and the
new controller has 3.25S, the new controller will be synchronized to have the 3.25P
firmware of the running controller.
To monitor this process, refer to
“Monitoring the Automatic Firmware Update with
a Recently Installed Controller FRU” on page 6-4
.
3. If you wish to have the most current version of firmware on your controllers,
download the latest firmware patch to the controllers as described the Release
Notes for the array.
