The lvm2 package in 13.04, 12.10, and 12.04 needs to be patched so that it recognizes the mtip32xx controllers that ship in many Dell PowerEdge systems. This is the Micron PCIe SSD disk controller.

Currently, LVM does not recognize these devices, so when you go to create a physical volume on them, you are met with the following error:'

"Device /dev/rssda1 not found (or ignored by filter)"

The issue can be worked around by adding the following line to /etc/lvm/lvm.conf:

devices {
...
           types = ["mtip32xx", 16]

}

However, in order to avoid confusion with users and to ensure that these devices 'just work' with LVM, the following patches have been requested:

These fixes have been incorporated into RHEL6 already.
