Hi Dimitre,
You have nothing to worry about, bug are everywhere. With HP-UX 11.31
you have a native multipath and agile storage stack, which means that
the device files names are based on the WWID, not based on domain id,
lun id, card instance and so on. I'm running several RAC clusters with
10.2 in prod, and 11g for test only.
Previously one had to use SGeRAC and Shared LVM to have the same
device names on all nodes, but now you don't need these. You have to
make sure that device files dedicated for the database under
/dev/rdisk/ (this will be the discovery string as GI) are owner by
oracle user. In case you delete them and rebuild device files (insf)
their ownership is changed back to root.
Personally I'm very happy with HP-UX as things are very straight
forward and can be done in only one way. Regular patches and drivers
are released, but still the prices has its word and Oracle decision to
discontinue the product for this platform. I have RAC installations
where servers are running for two years without a problem.
Regards,
Sve
