No HP performance agent running and PPATH devices are not usable. Would you please advice?

The Sun Bugid  6912703 was a Solaris 10 bug that was fixed with Kernel patch 144500-19. I do not see an equivalent reference for a Solaris 11. I verified that there were no HP agent running but neither complete re-scan at the OS level followed by "powermt config" and "powermt check force reconfig", "powermt save", etc resolved the issue. Solaris 11 SRU 2q2014 - HPOvPerfMI -  11.11.025 and PPATH 5.5P2.

So ctds were configured and the format can see them but neither /devices/pseudo/emcp@xxxx nor the emcpower a entries in the format utility are there for the new disks.

Thanks. Hugo
