These sorts of messages would indicate that LVM was updated without the device-mapper RPM also being updated. Digging deeper, it looks like a version of LVM was installed that is at a higher level than we've shipped for SLES11 SP3. According to http://upstream-tracker.org/compat_reports/lvm2/2.02.84_to_2.02.89/abi_compat_report.html the symbol in the error message was introduced in LVM version 2.02.89, and SLES11 SP3 is at 2.02.84. I have a SLES11 SP3 test system that has the latest lvm2 and device-mapper packages on it. That symbol doesn't show up in either of them. > I am not sure if the latest maintenance has anything to do with it or it > is just coincidence.

I would try booting from an installation kernel/ramdisk and see if I could assemble the VG from there, mount the root file system, and any other file systems on that, and chroot into the environment to see just what RPM thinks is installed.
