5. Unpack the new controller. Save all packing materials in case you have to return a controller.
6. Make sure that both controllers have the same host port adapter, DIMM size, and options.
7. If controller A contains an optional host port adapter, install an identical optional host port adapter
in the new controller. See “Installing an optional host port adapter or replacing a failed host port
adapter” on page 5-9 for instructions.
8. Remove the controller filler panel from the bay:
a. Open the two release levers. The filler panel moves out of the bay approximately 0.6 cm (0.25
inch).
b. Pull the filler panel out of the bay.
c. Place the filler panel in a safe place for future use.
9. Install the new controller.
Note: The following illustration shows installing controller A. Be sure to install the new controller in
the rightmost bay, as controller B.
10. Wait up to 5 minutes for the Storage Manager software to recognize the new controller.
11. Connect the host interface cables to the controller. See “Cabling the DS3500 storage subsystem” on
page 3-1 for more information.
12. Make sure that all storage enclosure connections have been completed (see the dual-controller
topologies in “DS3500 storage subsystem drive cabling topologies” on page 3-21); then, connect the
SAS drive expansion cable from the right ESM in the last storage enclosure in the chain to the drive
expansion port on controller B of the DS3500.
13. Wait up to 5 to 10 minutes for the Storage Manager software to report the drives and the redundant
drive path.
14. Verify the state of the LEDs on the newly inserted controller. See “Controller LEDs” on page 4-9. You
can also use the Subsystem Management window to identify any new faults. Do any storage
subsystems have a fault (Needs Attention) status?
v
Yes: Click Recovery Guru in the Subsystem Management window toolbar, and complete the
recovery procedure. If the problem remains, contact your IBM technical-support representative.
v
No: Go to step 15.
15. Use the Storage Manager software to print a new storage subsystem profile.
Release
levers
a. Make sure that the release levers on the controller are in the open position.
b.
Slide the controller into the bay until it stops.
c. Push the release levers to the closed position.
