5283.0. "SCSI Clusters with Cluster Client Software" by FJIV01::KAY () Wed Apr 16 1997 06:18

    Is it possible to configure a SCSI cluster using two Alphastation 255's 
    using the internal SCSI controller and the Cluster Client Software that 
    come with NAS150?
    
    According to the Cluster SPD everything is supported except the client 
    cannot vote in the cluster or act as an MSCP server.
    
    Would the inability to Vote prevent the cluster from forming a quorum
    and booting. 
    
    Also what would happen should one Alphastation fail.
    
    Thanks
    Barry

	You need at least one full VMScluster license. : Would the inability to Vote prevent the cluster from forming a quorum : and booting. I'm not sure if there are currently any technical prohibitions that would prevent this from a technical standpoint, but there certainly _are_ licensing prohibitions -- the customer would be in violation of the software license agreement. And technical prohibitions that might limit or might prevent this configuration may be added at any time in the future. : Also what would happen should one Alphastation fail. If there are sufficient votes on the remaining node (either directly, or via a quorum disk), processing would continue. If not, the VMScluster would initiate a "user data integrity interlock" -- better known as a "quorum hang".
