Make a note of the controllers listed. Use this information to identify the unknown controller.
The controller pairs appear with the known controller listed first followed by the unknown controller. The name or IP address
of the known controller appears, with its associated storage subsystem and a description of the location of the known controller.
The known controllers are identified as the controller in either slot A or slot B.
Perform one of these actions, depending on the type of storage subsystem that you are correcting:
You are correcting an out-of-band managed storage subsystem – Go to step 4.
You are correcting an in-band managed storage subsystem – Go to step 12.
Click Add More.
On the Add Storage Subsystem dialog, specify the name or the IP address of the controller that was listed in the Partially Managed Storage Subsystems dialog with an Unknown designation, and click Add.
Perform one of these actions, based on what appears on your screen:
The Add Storage Subsystem dialog appears again, and the “Added successfully” message appears: You have resolved the partially managed condition for
the particular controller. Go to step 9.
A Connection Problem dialog appears with the message “The specified storage subsystem was not accessible. Do you want to add it as an Unidentified
Storage Subsystem?”: Click No. Either a problem exists with the physical connection or the controller has a problem. Go to step 7.
Make sure that these conditions are met:
The Ethernet cable into the controller is not visibly damaged and is securely connected.
The applicable network configuration tasks have been performed, for example, IP address assigned to the controller, and so
on.
The controller is network accessible. One way to make sure that the controller can be reached is to type one of these commands
on a command line and press Enter.
ping Host_name_of_the_controller
ping IP_address_of_the_controller
Perform one of these actions, depending on the problem:
A cable or network accessibility problem occurred – Fix the problem, and go to step 9.
A cable or network accessibility problem did not occur – Turn off the power to the controller module, turn on the power to the controller module, and go to step 5. If the Connection Problem dialog appears again, you might have a faulty controller. Contact your representative.
Repeat step 5 for each controller that is associated with a directly managed storage subsystem that was listed with an Unknown designation.
When you are finished, go to step 10.
When you have added all names or IP addresses, from the Add Storage Subsystem dialog, click Close.
Perform one of these actions, depending on the result of the previous step:
The Partially Managed Storage Subsystems dialog appears again – Either you have not resolved all of the directly managed storage subsystems or the remaining controllers are associated
with in-band storage subsystems. Go to step 12.
The Partially Managed Storage Subsystems dialog does not appear again – You have resolved all partially managed situations. You have completed this procedure.
On the Partially Managed Storage Subsystems dialog, click Exit.
The host-agent software could not detect the controller due to one of these reasons:
A connection problem exists.
The controller was installed or replaced since the last time the host-agent software was started.
Check the connections, and rescan the controller by using this procedure.
Check the external cable between the host bus adapter and the controller to make sure that it is securely connected.
Restart the host-agent software on the host through which you are having problems detecting the controller.
Highlight the host in the Tree view of the Enterprise Management Window.
To try to detect the controller in the storage subsystem, select Tools >> Rescan.
Perform one of these actions, depending on what appears on your screen.
The menu option is grayed out (unavailable) or the controller associated with this in-band storage subsystem is no longer
listed. You have completed this procedure.
The controller and its associated storage subsystem are still listed. Go to step g .
Use the hot_add utility to register the logical drives so that the host-agent can communicate with both controllers, and repeat step 12. To use the utility, type hot_add on the command line and press Enter.
Turn off the power to the controller module, turn on the power to the controller module, and repeat step 12. If the controller continues to be listed in the Partially Managed Storage Subsystems dialog, you might have a faulty controller. Contact your representative.
Repeat step 12 for each controller associated with an in-band storage subsystem that was listed with an Unknown designation.
