# pkginfo -l EMCpower Verify the powerpath is installed
# modinfo | grep emcp Verify the PowerPath kernel extension is loaded on the host
# powermt display dev=all Verify the PowerPath devices are configured on the host

If the output of powermt display dev=all indicates that some storage system logical devices are not configured as Powerpath devices ( Go to next command otherwise no need to exceute powercf -q and powermt config command and reboot command )
   
# powercf -q Configure any missing logical devices
# powermt config Configure any missing logical devices
# reboot — -r Reboot the system

# powermt display dev=all Verify the PowerPath devices are configured on the host
# /etc/init.d/eccmad start Start EMC monitoring agent
# inq Check disk information
   
– Finally, check whether any paths remain unlicensed:  
# powermt display | grep -i unlic  
# powermt display dev=all | grep -i unlic  
   
– If any paths above show up as unlicensed then do this:  
# powermt set policy=so  # Symmetrix optimised, to be used for Symmetrix LUNs
# powermt set policy=co  # Clariion optimised, to be used for Clariion LUNs
# powermt display | grep count You can find out the type of SAN LUNs through:
   
– Doublecheck, no unlicensed paths should be present at this stage:  
# powermt display | grep -i unlic  
# powermt display dev=all | grep -i unlic  
   
powermt set policy=so dev=all  
powermt display dev=all
