When you perform a discovery request and choose to discover platforms by platform type, the available platforms appear in a drop-down menu. This drop-down menu is located under the Filters tab in the New Discovery Request dialog box.
The drop–down menu does not include entries for the following Sun Enterprise Ultra servers:
Sun Enterprise Ultra 2
Sun Enterprise Ultra 5
Sun Enterprise Ultra 10
Workaround: If you need to perform a discovery request for any of the preceding Sun Enterprise Ultra servers, perform the request manually.
