19. Check the LEDs on the new controller to make sure that the controller is fully
operational.
20. Use the DS3000 Storage Manager Subsystem Management window to check
the status of all components in the storage subsystem.
v If the new controller is online and the DS3000 Storage Manager Subsystem
Management window indicates normal operation, go to step 23.
v If the new controller is online and the DS3000 Storage Manager Subsystem
Management window indicates a problem status, go to “Troubleshooting the
storage subsystem” on page 51.
v If the new controller is offline, continue with step 21.
21. If the newly inserted controller is in an offline state, see the DS3000 Storage
Manager online help for instructions on bringing the controller online. If
necessary, open the DS3000 Storage Manager Subsystem Management
window and place the controller online; select the offline controller and click
Advanced → Recovery → Place controller online.
22. Verify the state of the LEDs on the newly inserted controller. See “Controller
LEDs” on page 53. You can also use the DS3000 Storage Manager
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 23.
23. Use the DS3000 Storage Manager software to print a new storage subsystem
profile.
Installing an optional SAS host port adapter
Note: The DS3200 SAS 2-Port Daughter Card option is referred to in this
document as host port adapter.
This section explains how to install an optional SAS host port adapter into a
controller.
Attention: If you install a host port adapter in a controller, you must make sure
that an identical host port adapter is installed in the other controller on the DS3200,
for correct operation of the controllers.
The SAS host port adapter adds two additional host ports to the controller.
To install a SAS host port adapter, complete the following steps.
Attention: To prevent data loss, you must shut down the storage subsystem
before you remove the controller from the chassis. For the correct shutdown
sequence, see “Turning off the storage subsystem” on page 55.
1. Read the safety information that begins on page xi and “Best practices
guidelines” on page 6.
2. Turn off the storage subsystem (see “Turning off the storage subsystem” on
page 55).
3. Disconnect the cables that are connected to the controller.
