Verify the PowerPath
Commands Are in
Your Path
Verify PowerPath Devices Are Configured on the Host
Check that the PowerPath commands are in your path. PowerPath installation modifies the /etc/profile and /etc/.login files to run the PowerPath setup scripts, which modify the PATH, LD_LIBRARY_PATH, LD_LIBRARY_PATH_64, and MANPATH variables on the host.
If you find that the PowerPath commands are not in your path, check the /.profile, /.login, and /.cshrc scripts to see if they are overwriting the changes made by the PowerPath setup scripts.
To verify that PowerPath devices are configured on the host:
1.Enter:
powermt display dev=all
You should see output like the following:
Pseudo name=emcpower0a Symmetrix ID=000000003269; Logical device ID=048
state=alive; policy=SymmOpt; priority=0;
