displaying it in the topology. Refer to Oracle documentation for information on how to remove the deleted Oracle instance from the TNS listener port.

Requirements for Discovering Oracle

To discover Oracle:

•The management software for Oracle must be installed. For information about installing the management software for Oracle, refer to the Installation Guide.

•By default, the software sets the TNS Listener Port to 1521. If you use another port, you can change the port number on the Discovery Targets tab.

•Oracle discovery relies on the TNS networking substrate on which Oracle is built (TNS is Oracle's proprietary protocol). The software does not use TNS listener password. If you have set a TNS Listener password, the software is not able to discover the Oracle instances serviced by the listener.

Do Not Run Overlapping Discovery Schedules

If you are creating multiple Discovery schedules, care must be taken to avoid scheduling conflicts—concurrently scheduled Discovery tasks—and that each scheduled task has enough time to start and finish before the next Discovery task is scheduled to start. For example, if a scheduled Discovery is still in progress when another scheduled Discovery attempts to start, the Discovery task that attempts to start will not start because the first Discovery is still running. The Discovery that is unable to start is re-scheduled according to its recurring rule. If the Discovery task is scheduled to run on a daily basis for example, then the Discovery will start again on the next day. To check the status of scheduled Discovery tasks, view the appiq.log file in the following directory:

[Install_Dir]\jbossandjetty\server\appiq\logs

"This storage system uses unsupported firmware. ManagementClassName: ???"

Message

The following message is displayed when an Engenio storage system is discovered, and is running unsupported firmware:

“This storage system uses unsupported firmware. ManagementClassName: ???”

The management class name for the unsupported array is displayed in the message.

New releases of storage system firmware are supported with each new release of this software. See the Support Matrix for the latest information on supported firmware.
