Figured so. Thanks for the response. I recall, a long while ago (6.2 version days) that there was some chatter to have an alternative to the raw partitions for cluster node state sharing for Piranha. Something along the lines of how IBM's HACMP (for AIX) accomplishes it - along the heartbeat networks (serial, network and/or across SSA loops) via cluster daemons. Each node has a local memory store of the state of the cluster, resource groups and nodes and all shares with all. It was unofficial chatter, but the discussion did come up. Do you know if there is any current discussion for that? Thanks again for your speedy response. Tim Burke wrote: > Philip Greer wrote: > >> My initial thoughts is 'yep'.
