Samples for Determining HAF Message Numbers

As described earlier, the mm portion of message number HAFImmnn is associated with HMC event message types. The following samples show how to determine HAF message numbers for an IBM HMC.

This sample shows 14 different event types that are listed in IBM manual SC28-8141-09. The following names and hexadecimal values of the event types are listed in numeric order with the associated HAF message number included at the end in parenthesis:

• HWMCA_EVENT_COMMAND_RESPONSE 0x00000000 (01)
• HWMCA_EVENT_MESSAGE 0x00000001 (02)
• HWMCA_EVENT_STATUS_CHANGE 0x00000002 (03)
• HWMCA_EVENT_NAME_CHANGE 0x00000004 (04)
• HWMCA_EVENT_ACTIVATE_PROF_CHANGE 0x00000008 (05)
• HWMCA_EVENT_CREATED 0x00000010 (06)
• HWMCA_EVENT_DESTROYED 0x00000020 (07)
• HWMCA_EVENT_EXCEPTION_STATE 0x00000040 (08)
• HWMCA_EVENT_ENDED 0x00000080 (09)
• HWMCA_EVENT_HARDWARE_MESSAGE 0x00000100 (10)
• HWMCA_EVENT_OPSYS_MESSAGE 0x00000200 (11)
• HWMCA_EVENT_NO_REFRESH_MESSAGE 0x00000400 (12)
• HWMCA_EVENT_STARTED 0x00000800 (13)
• HWMCA_EVENT_HARDWARE_MESSAGE_DELETE 0x00001000 (14)

Other code levels for an IBM HMC could number these event types differently or could have more or fewer event types. In those cases, the HAF message numbers would change accordingly, but you would use the same process to determine what they should be.

Keep in mind that the event portion of a HAF message contains the event type for the message. For example, the third word of a HAFI05nn message for the previously mentioned level of IBM HMC would be ACTIVATE_PROF_CHANGE.
