Hi AIX 6.1 HA 5.5 Oracle rdbms/clusterware: 10.2.0.4 A network outage on the public interface led to the VIP status becoming 'unknown' in one cluster of 2 LPARs. What exactly does the STATUS=UNKNOWN signify in the crs_stat output ? Why doesn't the status go OFFLINE instead ? The 'unknown' status doesn't kead to the vip failing over with a simple 'srvctl start'. Instead we need to crs_stop the 'unknown' resource and then crs_start it. What could be causing the status to go 'unknown' instead of 'offline' ? I've hunted around, but there are plenty of docs detailing what needs to be done to make it online, but I havn't been able to locate anything on the reasons. Any pointers / suggestions ? Thanks Sanjay
