CA Performance Manager 3.5 includes Vertica 8.1. Vertica added support for LVM's late in the 8.1 release so specific support was not included in CA Performance Manager 3.5 installation guide or installation scripts.
There is very specific guidance in the Vertica docs that outline how LVM's need to be configured. As long as these are followed, we have support from Vertica. So CA Technologies will support LVM's on CAPM 3.5. providing the guidelines from Vertica are met.
