This extension command can only be used with an Itanium-based target computer.

Remarks

This extension displays the interrupt history record without referencing the program counter symbols. To display the interrupt history record using the program counter symbols, use the !ihs extension. To enable the interrupt history record, add /configflag=32 to the boot entry options.

Here is an example of the output from this extension:
