Hey all. I'm in the process of testing a conversion process of an ERP system from physical to virtual. At this time, the system runs on Red Hat Enterprise 5.6 using PowerPath 5.6 to connect 8 SSD LUNS in an LVM volume group. My plan is to connect these LUNs to a Red Hat virtual machine (vSphere 5) and use RDM (raw device map) to connect the individual LUNs the the VM. When I do this, I see the new disk(s) appear, but they show no valid partitions and pvscan doesn't show any exported volume group. However, if I connect these LUNs via raw device mapping using physical mode and start up PowerPath, I see the /dev/emcpower device and I am able to import the volume group using the pseudo device names (even though powerpath only shows a single SAS connection to the device). Is there any way to import these LUNs without having PowerPath running/installed? Is my only option to migrate the data to a new volume group? Any help in this matter would be greatly appreciated. I would like to keep the LUN configuration in tact if at all possible.

Thanks!
