Re: Explanation of powermt display dev=all command output in HP-UX

Hello,

the 0/0/10/1/0.1.0.0.0 is HPUX hardware path notation. What exactly each number means depends on the type of the hardware you are using. Basically this string represents the entire path to the device from controller over PCI bridges, bus adapters, PCI slots to particular disk. Maybe you could post the type of your server. Use this command:

# model

I haven't used Powerpath yet, but would assume that "optimal" in the above output means that the particular device works allright and load balancing is in effect. Degraded would mean that one or more paths have failed. That's what I think.
