16. Wait up to 5 minutes for the Storage Manager software to recognize the controller.
17.
Check the LEDs on the controller to make sure that the controller is fully operational.
18. Use the Subsystem Management window to check the status of all components in the storage
subsystem.
v
If the controller is online and the Subsystem Management window indicates normal operation, go
to step 21.
v If the controller is online and the Subsystem Management window indicates a problem status, go
to the Troubleshooting section of this document.
v
If the controller is offline, continue with step 19.
19.
If the newly inserted controller is in an offline state, see the Storage Manager online help for
instructions on bringing the controller online. If necessary, open the Subsystem Management window
and place the controller online; select the offline controller and click
Advanced → Recovery → Place
controller online .
20. Verify the state of the LEDs on the newly inserted controller. See the "Controlling LEDs" section in
this document. 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 21.
21. Use the Storage Manager software to print a new storage subsystem profile.
Removing an optional host interface adapter
To remove a host interface adapter that is installed in a controller that is still installed in the storage
subsystem, complete the following steps, otherwise, go to step 5 on page 100.
1. Before you remove a controller from the storage subsystem, read “Safety” on page xi.
Attention: If the host interface adapter is going to be removed from both controllers, then you will
need to power off the subsystem. See “Turning off the storage subsystem” on page 83.
2. Disconnect the cables that are connected to the controller.
3. Remove the controller from the chassis.
