Hi Allen, As far as I know, if you want to connect the same disk to more than 2 nodes, the protocol to be used should be SCSI3
In your case you want to connect a disk to 3 nodes and hence the QD should be using the SCSI3 protocol You do not need to delete the whole cluster. Just boot up nodes 1 and 2. Then remove the quorum device. Then boot up node 3 ( this was the node which was panicking) After all the 3 nodes are up and formed a cluster, add the quorum device again Thanks, Tirthankar On Dec 14, 2007 3:56 PM, ALLEN, David <David.ALLEN at eur.crowncork.com> wrote: > Thanks for your quick reply.
