Reporting Problems

If you are unable to solve a problem with HP APA, do the following:

1.Read the release notes for HP APA to see if the problem is known. If it is, follow the solution offered to solve the problem.

2.Determine whether the product is still under warranty or whether your company purchased support services for the product. Your operations manager can supply you with the necessary information.

3.Access http://www.itrc.hp.com and search the technical knowledge databases to determine if the problem you are experiencing has already been reported. The type of documentation and resources you have access to depend on your level of entitlement.

NOTE: The ITRC resource forums at http://www.itrc.hp.com offer peer-to-peer support to solve problems and are free to users after registration.

If this is a new problem or if you need additional help, log your problem with the HP Response Center, either on line through the support case manager at http://www.itrc.hp.com, or by calling HP Support. If your warranty has expired or if you do not have a valid support contract for your product, you can still obtain support services for a fee, based on the amount of time and material required to solve your problem.

4.If you are requested to supply any information pertaining to the problem, gather the necessary information and submit it. The following section describes the information that you might be asked to submit.

Gathering Information

To gather information to report a problem, complete the following steps:

1.Write a complete description of the problem. Describe the events leading up to and including the problem. Attempt to describe the source and symptoms of the problem.

Include in your description: HP-UX commands used; communication subsystem commands used; job streams; result codes and messages; and data that can reproduce the problem. Also provide a network map with the host name, IP (Internet address), and station address of each system connected to the HP system.

Illustrate as clearly as possible the context of any message(s). Prepare copies of information displayed at the system console and user terminal.

2.Obtain the version, update, and fix information for all software. To check the HP APA version number, enter the following command:

# what /stand/vmunix grep -i -e hp_apa -e pagp -e lacp

To check the version of your kernel, enter uname -r.

This information enables HP to determine if the problem is already known and if the correct software is installed at your site.

3.Prepare copies of the following files:
