All devices masked to Linux server show as pseudo name = ???
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?

powermt display dev=sdij
Pseudo name=emcpowercb

Logical device ID=0D0B
Device WWN=
state=alive; policy=BasicFailover; queued-IOs=0

Hello Ian. I am good now. The command you gave was very helpful. Also I found in a document all of the files and directories that are created when you install powerpath. After uninstalling powerpath I went in to the server and removed any of the files and directories that still remained. I then did a clean install of powerpath and the pseudo names showed up correctly.
