12. Unpack the new RAID controller with the 1-GB cache. Verify that the battery is
in the controller by opening the DS4300 controller CRU, using step 6 through
step 9 of "Replacing the battery in the RAID controller" on page 140. If there is
no battery in the new DS4300 controller, remove the battery from the old
controller and install it in the new controller.
Set the RAID controllers on a dry, level surface away from magnetic fields.
Save the packing material and documentation in case you need to return the
RAID controllers.
13. If DHCP/BootP was used to automatically set the IP address of the controller,
record the MAC address of the upgrade controller and modify the existing
DHCP/BootP record of the RAID controller to be upgraded with the new MAC
address. Failure to modify the DHCP/BootP record will result in problems trying
to manage the storage subsystem using the existing IP address. This step
must be performed before you insert the upgrade controller into the DS4000
storage subsystem.
14. Install each of the new RAID controllers, as follows:
a. Slide the RAID controller all the way into the empty slot.
b. Close both levers until the latch locks into place.
15. Insert the SFPs according to the instructions in "Installing SFP modules" on
page 33.
16. Connect the fibre-channel cables to their original locations on both of the
upgraded controllers, according to the instructions in Chapter 3, "Cabling the
storage subsystem," on page 29.
17. Turn on the DS4300 storage subsystem.
18. Wait approximately one minute, and then check the green Host Loop LED,
green Expansion Loop LED, and amber Fault LED on the new RAID
controllers.
Note: If the Host Loop LED or the Expansion Loop LED is off, the RAID
controller might not be inserted correctly. Remove the RAID controller
and reinsert it.
19. Check that the controller is online. Use either of the two following methods:
v Use the Storage Manager client to verify that the controllers are online (up)
and running by selecting the menu option to display the properties of the
