Hi,
You can find instructions how to log a case in the following link: http://support.openview.hp.com/pdf/HP_Software_Customer_Support_Handbook.pdf under the chapter: Submit and Manage Service Requests and Change Requests
You can open an incident by phone or after logging in https://softwaresupport.hp.com/ you can submit a request under the section submit a New Service request. You will need to link your SAID to your account. Details are described in the Software Customer Support Handbook and under About -> Getting Started -> Service Request
Kind regards,
Vesela
