Arty, The PAV document that was pointed out already might be of some help. Failing that, you can use mdadm to create multi-pathed software raid volumes, and use those to create your PVs, etc. You'll probably have to make sure everything is backed up and do a restore afterwards, though, because I don't think you can keep your data going this route.

We use "pvpath" and LVM multipathing for a dozen Linux guests running SLES8. Using SLES9, "pvcreate" works fine, but "vgcreate" complains about duplicate "PV" identifiers (on the alternate path devices). Although "vgcreate" indicates that the volume group was sucessfully created, it isn't. I have 8 paths to each FCP LUN on an IBM ESS. So, /dev/sd[b-h] are the same devices as /dev/sda. Works just fine under SLES8. I am able to define the LUN mapping in SLES9 using YaST2 LVM. I just can't convince "vgcreate" to do the right thing. Any ideas?
