Hi all, We installed a RH 5.2 system where the root file system is on a logical volume comprising a single physical volume which is on zFCP LUN. Later we added another zFCP LUN, updated zfcp.conf and added the physical volume to the LV. This appeared to be OK until we had a scheduled reboot of the system. The boot starts OK until: Scanning logical volumes Reading all physical volumes. This may take a while... Couldn't find device with uuid 'YD0yYY-Ty0J-I303-2jqQ-4bYs-SSFx-QyzQzc'. Found volume group "VolGroup00" using metadata type lvm2 Eventually it gives up because it cannot mount the root file system because the logical volume is incomplete.I was able to access both LUNs from another system and I ran vgimport on that system to check the zfcp.conf. It seems to be OK. Does anyone know if I need some entries in the zipl.conf file for the zfcp LUNs?. The RHEL 7 (beta) documentation states that if the root file system is on a logical volume using zFCP then entries are needed in zipl.conf but I cannot find any instructions for RHEL 5, or indeed any documentation of the syntax for zipl.conf. The zipl.conf which was generated by the RHEL 5 installer does not have any zfcp entries in zipl.conf.We could just install a new system with a larger root file system but I would like to be able to fix this if possible.Keith Gooding
