Jens, thanks for the reply. What should I look for in Partitioner to determine if this is an LVM setup? Unfortunately I am not familiar with how LVM sets up partitions. What I see in partitioner is as follows:

ServerName
Hard Disks
sda
sda1
sda2
RAID
Volume Management
system
root
swap
tmp

I don't know if that helps or not.

You think I should first upgrade from SLES 11 SP2 to SLES 11 SP3, then to SP4? What if I don't see the root partition listed in the SLES 11 SP3 installation process? I didn't realize that I could not upgrade directly from SLES 11 SP2 to SLES 11 SP4.
