** Description changed:
- 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.
+ [Impact]
+
+ * Out of the box lvm does not work on some devices:
+ - Quantal: Micron PCIe SSD devices
+ - Preicse: Micron PCIe SSD and FusionIO devices
+
+ * This is hardware enabled backport, specifically to avoid forcing
+ people to manually modify lvm.conf to enabled those devices to be
+ visible by lvm.
+
+ [Test Case]
+
+ * Create VG group on a Micron PCIe SSD and/or FusionIO device
+ * Note that vgchange -a y, does not automatically activate that VG group,
unless this update is installed or /etc/lvm/lvm.conf is manually modified.
+
+ [Regression Potential]
+
+ * This is adding an additional default filter, which one could add
+ manual in lvm.conf. Tested and included upstream as well as other
+ distributions.
+
+ [Other Info - Original bug report]

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:
+ or for Fusion
+
+ devices {
+ ...
+ types = ["fio", 16]
+
+ }

These fixes have been incorporated into Fedora / RHEL.
