The latest 11.31 HP-UX version uses native multipathing with the help of the new IO stack. However if you’re on an older version, it was common along many customers to get a Powerpath license from EMC. It is to be used for building an active/active solution. Now here is a quick’n'short cheatsheet for the most useful powerpath commands on HP-UX:
-
# powermt config - initialise the configuration
-
# powermt save - save the configuration
-
# powermt check - discover luns
-
# powermt display dev=all - display the complete config
