3.Verify that the PowerPath and PowerPath Volume Manager kernel extensions are loaded on the host. Enter:

modinfo grep -i emc

You should see output like the following:

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; queued-IOs=0
