I have a Linux server running RedHat 6.7 and when I run powermt display dev=all command all the devices masked to this server their pseudo names show up as being ???. Per KB455716 i have run the ctree utility to fix the corruption and removed the 2 files /etc/emcp_devilishness, /etc/emcp_devicesDB.dat. I am running Powerpath 6.0 SP1 and have glibc 2.12-1.92 installed. I have also uninstalled and reinstalled PowerPath. Has anyone seen this issue before and been able to fix it?
