IMPORTANT: The IP addresses of excluded elements appear in the discovery (Tools > Storage Essentials > Home > Discovery > Setup), topology (Tools > Storage Essentials > Home > Discovery

>Topology), and Discovery Data Collection (Options > Storage Essentials > Discovery > Run Discovery Data Collection), lists. The management server does not display additional information about excluded elements in the user interface. The management server, however, does mention in the logs (Tools > Storage Essentials > Home > Discovery > View Logs) that a provider instance has been created for an excluded element. You can ignore this log message.

To modify the cimom.mcdata.exclude property:

1.Select Options > Storage Essentials > Manage Product Health, and then click Advanced in the Disk Space tree.

2.Click Show Default Properties at the bottom of the page.

3.Copy the cimom.mcdata.exclude property.

4.Click Close to return to the Advanced page.

5.Paste the copied text into the Custom Properties box.

6.Make your changes to the text in the Custom Properties box. Remove the pound (#) symbol in front of the property to make sure it is not commented out.

7.Add the WWNs corresponding to the switches you want to exclude from discovery. Separate additional WWNs with a comma, as shown by the following example:

cimom.mcdata.exclude=1000080088A07024,1000080088A0D0B6

where 1000080088A07024 and 1000080088A0D0B6 are the WWNs for McDATA and Connectrix switches.

8.When you are done, click Save.

Managing McDATA and EMC Connectrix Switches

Whenever you add, remove or replace McDATA or EMC Connectrix switches in an already-discovered service processor, you must make the management server aware of those changes by performing Discovery Data Collection to obtain information about the new switches from the service processor. For more information about adding switches, see, ”Adding McDATA and EMC Connectrix Switches” on page 132.

When you remove switches from the service processor, you must remove them from the management server. For more information about removing switches, see ”Removing McDATA and EMC Connectrix Switches” on page 133.

When you replace McDATA or EMC Connectrix switches, you add and remove the switches as described previously. For more information, see ”Replacing McDATA and EMC Connectrix Switches” on page 133.

Adding McDATA and EMC Connectrix Switches

After you add switches to an existing service processor, you must perform Discovery Data Collection, as described in the following steps. If you are adding switches to a service processor that has not been discovered yet, see the topic, ”Discovering McDATA and EMC Connectrix Switches” on page 124.
