How to Correct a Partially Managed Condition for a Directly Managed Storage Subsystem

The following procedure is only for directly managed storage subsystems. For host-agent managed devices, see How to Correct a Partially Managed Condition for a Host-Agent Managed Storage Subsystem.

Note: If you already have the Partially Managed Devices dialog displayed, you can skip step 1 below.

1

Select the View >> Partially Managed Devices pull-down menu option.

Result: The Partially Managed Devices dialog displays.

2

Make a note of the controllers listed (both known and unknown). Use this information to identify the unknown controller.

Note: The display shows controller pairs with the known controller listed first followed by the unknown controller. The display shows the known controller's name or IP address, its associated storage subsystem, and a description of the known controller's location (controller in Slot A or Slot B).

3

On the Partially Managed Devices dialog, select Add More.

Result: The Partially Managed Devices dialog closes. The Add Device dialog is displayed.

4

On the Add Device dialog, specify the Name or IP Address of the controller that was listed in the Partially Managed Devices dialog with an Unknown designation, then select Add.

Result: The Connecting message dialog is displayed while the Enterprise Management software attempts to contact the specified Name or IP address.

If...

Then...

The Add Device dialog is displayed again and the message "Added successfully" appears

You have resolved the partially managed condition for the particular controller, go to step 6.

A Connection Problem dialog displays as follows:

"The specified device was not accessible. Do you want to add it as an Unidentified Device?"

Select No.

There is either a problem with the physical connection or a faulty controller. Go to step 5.

5

Check to make sure:

  • The Ethernet cable into the controller is not visibly damaged and is securely connected.
  • The appropriate network configuration tasks have been performed (for example, IP address assigned to the controller, and so on). Refer to the storage management software installation guide for details.
  • The controller is network-accessible. One way to do this is to use the ping command to verify that the controller can be reached. Use the form ping <Host name or IP address of the controller>.

If...

Then...

There was a cable or network accessibility problem

Fix the problem and then repeat step 4.

There wasn't a cable or network accessibility problem

Turn the power to the controller enclosure off and then on and then repeat step 4. If you continue to receive the Connection Problem dialog, you may have a faulty controller. Contact your technical support representative.

6

Repeat step 4 for each controller that is associated with a directly managed storage subsystem that was listed with an Unknown designation, then go to step 7.

7

When you have added all names or IP addresses, select Close from the Add Device dialog.

If...

Then...

The Partially Managed Devices dialog is displayed again.

Either you have not resolved all of the directly managed storage subsystems or the remaining controllers listed are associated with host-agent managed storage subsystems. For more information, see How to Correct a Partially Managed Condition for Host-Agent Managed Storage Subsystems.

The Partially Managed Devices dialog does NOT display again

You have resolved all partially managed situations.

YOU ARE FINISHED WITH THIS PROCEDURE.

How to Correct a Partially Managed Condition for a Host-Agent Managed Storage Subsystem

Note: If you already have the Partially Managed Devices dialog displayed, you can skip step 1 below.

1

Select the View >> Partially Managed Devices pull-down menu option.

Result: The Partially Managed Devices dialog is displayed.

2

Make a note of the controllers listed (both known and unknown). Use this information to identify the unknown controller.

Note: The display shows controller pairs with the known controller listed first followed by the unknown controller. The display shows the name or IP address of the host, the associated storage subsystem, and a description of the known controller's location (Slot A or B).

3

On the Partially Managed Devices dialog, select Exit.

Result: The Partially Managed Devices dialog is closed.

4

The two most likely reasons that the host-agent software could not detect the controller are:

  • There is a connection problem.

-OR-

  • The controller was installed or replaced since the last time the host-agent software was started.

Verify the connections and rescan the controller using the following procedure:

A

Check the external cable between the host adapter and the controller to make sure that it is securely connected.

B

Restart the host-agent software on the host through which you are having problems detecting the controller. Refer to the storage management software installation guide on how to restart the host-agent.

C

Highlight the host in the Device Tree View of the Enterprise Management Window and then select the Tools >> Rescan option to attempt to detect the controller in the storage subsystem.

D

Determine if the problem has been corrected by selecting the View >> Partially Managed Devices option.

If...

Then...

  • The menu option is grayed out (unavailable)

-OR-

  • The controller associated with this host-agent managed storage subsystem is no longer listed.

You are finished with this procedure.

The controller and associated storage subsystem are still listed.

Try the following procedures, one at a time:

  • Use the hot_add utility to register the access logical drive so the host-agent can communicate with both controllers, and then repeat step 4. (To use the utility, type hot_add at the command line.)
  • Turn the power to the controller enclosure off and then on and then repeat step 4. If the controller continues to be listed in the Partially Managed Devices dialog, you may have a faulty controller. Contact your technical support representative.

5

Repeat step 4 for each controller associated with a host-agent managed storage subsystem that was listed with an Unknown designation.
