PowerPath Question

[Sunil Patil]

Hi,

I have a EMC PowerPath 5.3 software installed on my linux machine RHEL 5.2.

I am having some multipathed JBOD disks and PowerPath is not able to
detect/recognise them. Is it that PowerPath works only with EMC
storage devices like clarrion and symmetrix and few other mentioned
below?

powermt <command> [class=all|clariion|ess|hitachi|hphsx|hpxp|invista|symm]

There is something called class=all, what does this mean?

Thanks,
Sunil
