I have MPIO installed on the SUN cluster servers. But I want to install PowerPath on the hosts.
PowerPath is not compatible with MPIO, and therefore cannot write to native Symmetrix devices using dd if both
PowerPath and mpxio are installed on the same host.
I don't want to uninstall the MPIO and still have PowerPath configure the symmetrix devices.
Can anyone suggest something?

MPxIO is installed by default on Solaris.  As long as you are not using it to manage the multiple paths, you can install Power Path and just use the EMCPower devices versus the cxtxdx devices.  I haven't had a problem with this at all.  You will get MPxIO messages in your /var/adm/messages file about multiple paths not being managed, but those are informational and not harmful.
