  Unfortunately it's no chance to do it. And, to be honest, no point to do so as the purpose of the whole thing is to support porting from AXP 7.3-2 to I8.4

  I removed DISK_QUORUM and QDSKVOTES from Alpha and it booted successfully. Integrity entered later with quorum disk. So now two nodes and quorum disk are in the cluster, but Alpha doesn't know about quorum disk.  So network was proven to work normally. The configuration is working but looks somewhat ..inaccurate. Yes, I can live with it and can connect Alpha and Interity directly with crossover ethernet cable to leave network folks out of game. But I still have no idea why Alpha doesn't want to work with fibre quorum disk.

  Yes, it's my first cluster and there is a lot of fun here for me.
Thank you very much, Hoff, for your comments. Yes, I searched your site forth and back before asking here :)
