HP-UX with PPath only uses 1 path
I've got an HP-UX machine with PowerPath installed and when we type "powermt show dev=all" we only see 1 active path per LUN.
I was thinking PP license or perhaps wrong registration in Navisphere.
Does anyone have any ideas what could be wrong here ?

On the array ensure you are using "No Auto Trespass"
In the agent.config file comment out the "OptionsSupported AutoTrespass" line.
