    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
