One more thing for clarification.......I can manually failover the
resource group (using the scswitch command) from the host with both I/O
paths disconnected, to the 2nd host in cluster. The problem is in
automated failover within cluster.
Thanks

Subject: failover through Sun Cluster 3.1 when both I/O paths are
disconnected
I have a 2 node cluster running SC 3.1, on V880s with Solaris 9. Both
systems are dual connected to HDS9970 through redundant brocade
switches. We are using MPXIO for path failover and SVM for disk
management. I have appropriate resource groups setup for failover with
resources (devices for Informix DB, application filesystems) depending
on SUNW.HAStoragePlus. Problem is that when I disconnect both paths to
the storage from a host, it does not failover resources to the 2nd node
on the cluster....the resource group remains online on the host with
both fiber channels disconnected. Do I need to change some resource
properties to get this failover working?
Rest of cluster integrity tests (there is a list of nearly 40 tests to
certify the cluster install.....bring a host down hard, soft,
disconnecting public/private network, etc.) all ran fine.
Thanks
Shadman
