 hi Experts,we have 2 node rac 10gr2(10.2.0.4) running on AIX6.1 with GPFS3.4, yesterday we face an issue of node eviction on 2nd node. at this moment we have only Db alert log and Cluster alert logs. in cluster alert log we can just review that heart beat of 2nd node is going down and at last its eviction happened. now we are confuse about how to find out which is cause for this node eviction . we have 2 major possibilities
                1- interconnect ethernet goes down  of 2nd node
2-gpfs ethernet goes does down     of 2nd node(gpfs used for OCR.VOTING,Datafiles,FRA)
