Adding a Storage Subsystem

Related Topics

Use this option to manually add a directly managed or host-agent managed storage subsystem to the management domain .

Note: The Automatic Discovery and Rescan options provide automatic mechanisms for discovering hosts and storage subsystems .

Important:

It can take several minutes for the Enterprise Management software to connect to the specified device.
Before using this option, verify that the appropriate network configuration tasks have been performed. Refer to the software installation guide for details.
To add a directly managed storage subsystem, make sure you provide the host name or IP address of each controller in the storage subsystem. Note that the dialog only allows you to add one address at a time.
To add a host-agent managed storage subsystem, add the host through which the storage subsystem is attached to the network. The host will then display in the Device Tree along with any attached storage subsystems.

How to Add a Storage Subsystem

1

Select one of the following:

Add Device toolbar button
Edit >> Add Device menu option
Storage management station node, then Add Device from the right-mouse pop-up menu.
Result: The Add Device dialog is displayed.

2

For a directly managed storage subsystem, enter a host name or IP address for one of the controllers in the storage subsystem. For a host-agent managed storage subsystem, enter a name or IP address for the host through which the storage subsystem is attached to the network.

3

Select OK.

Result: The Connecting message dialog is displayed while the software attempts to contact the specified device.

If...

Then...

The device was successfully accessed

The device is added to the Device Tree and the Device Table. Also, the Connecting message dialog closes and the Add Device dialog is displayed again with a confirmation of the device added. You can either add another device or select Close.

NOTE: If the storage subsystem is directly managed, you must add the second controller.

The device was NOT accessed because of an unresolved host name.

The Connection Error message dialog is displayed.

Select OK to return to the Add Device dialog. You can either enter a valid host name or select Close.

The device was NOT accessed because of an unsuccessful connection to the name or IP address of a controller in the storage subsystem or an unsuccessful connection to a host.

The Connection Problem message dialog is displayed.

Select Yes to add the device to the Device Tree view as an Unidentified Node and close the dialog (see note below). Select No to close the dialog without adding the device.

Note: If you add the device as an Unidentified Node, the Enterprise Management software retries the connection to this device at future intervals. If a future connection is made to this device that allows it to be identified, the node changes to either a host or a storage subsystem node, whichever is appropriate.

After selecting Yes or No, the Add Device dialog is displayed again. You can either add another device or select Close.

Important: If a Partially Managed Devices dialog displays after you have selected Close in the Add Device dialog, then one or more of the devices you have added is only partially manageable. (That is, only one controller in a storage subsystem has been defined or, in a host-agent managed storage subsystem, it means that only one controller can be contacted.) This dialog provides you with information to assist you in determining what devices still need to be defined. To see the Partially Managed Devices dialog, select View >> Partially Managed Devices in the EMW.
