AutoPath

Software Required

If the installation of HP AutoPath software fails during the kernel compilation due to an error similar to:

This behavior is cause because the SCSI Upper Layer Module is not installed. This is a requisite software for AutoPath on HP-UX 11.11. Newer versions of HP-UX already has this component copied during Cold Install or implement multipath solutions inside the kernel (HP-UX 11i v3).

The ULM-Service bundle must be installed to correct this problem.
