[Linux-cluster] SCSI PR fencing



Hi,
 
Consider a two node RHEL5 cluster that is configured with SCSI PR fencing but without a qdisk. In the event of network split, nodes will attempt to fence the other one. One of the node's (node that lost the race) key will be successfully removed from the disk and key of the node that won race will be present on the disk.
 
The question I have is that, in the event of a network split, is there a possibility (even remote) for both the nodes to "successfully" fence each other? That is key of both the nodes are successfully removed from the disk. 
 
I am trying draw comparision with HP iLO fencing mechanism, where there is possibily for the nodes to fence each and hence bringing down the entire cluster. 
 
Thanks,
Rajeev Purushottam
