Well, yeah, I see to a certain degree. I have to admit the whole device-mapper stuff irritates me on Linux. I don't want my 'df' output to show:
/dev/mapper/vg00-lvol6 I want it to show: /dev/vg00/lvol6 which is how I deal with it from the LVM side. I have done a minimal amount of work with SAN on Linux, so I'm not feeling the pain of dealing with that whole arena, which I agree does not have a unified feel. But, once you are at the PV level, its all abstraction in the same way as HP-UX.

Or are you using VxVM? No we are not using VxVM. Perhaps I am not referring to LVM specifically, but to the 'unified' feeling of the stack. For example, if I want to remove an LV/PV/VG/ physical LUN combination, I don't have to do the same nonsense as on Linux: manually remove dm-multipath mappings, manually delete the luns from /sys/block, remove them from HBA driver with an echo command to the driver, etc. How many versions of RHEL will go by before that same unified feeling is developed? -Eugene
