    Turn on a resource group:

    scswitch -Z -g nfs-rg
    

    Switchover a failover resource group:

    scswitch -z -g nfs-rg -h new_primary_node
    

    Change list of primaries for a scalable group:

    scswitch -z -g nfs-rd -h node1,node2,...
    

    Restart a resource group:

    scswitch -R -h node,node -g nfs-rg
    

    Evacuate all resources and resource groups from a node:

    scswitch -S -h node

    Disable a resource and its fault monitor:

    scswitch -n -j nfs-res
    

    Enable a resource and its fault monitor:

    scswitch -e -j nfs-res
    

    Disable fault monitor for a resource:

    scswitch -n -M -j nfs-res
    

    Enable fault monitor for a resource:

    Maintainance Operations[edit]

    Boot node outside of cluster

    boot -x (from prom)
    

    Place node into maintenance mode (NB, node will lose it's vote so primary node will not failure fence, ensure primary node is up and available before resuming secondary from maint)

    scconf -c -q node=nodename,maintstate

    scdidadm -r
    

    Switch disk devices between nodes

    scswith -z -D dgname -h nodename
    

    View cluster ntp config

    cat /etc/inet/ntp.conf.cluster
    

    Disable interface in IPMP group

    scswitch -c -j resource -h node -f STOP_FAILED
    

    Replaced a removed transport cable, this doesn't seem to work in the menu on SC3.2

    scconf -a -m endpoint=<hostname>:bge1,endpoint=<switch>@3
    

    Other Cluster Notes[edit]

    Oracle Logs[edit]

    Oracle Logs are at /var/opt/SUNWscor/oracle_server|listener sometimes only one node gets the logs tho so check both.

    Changing NFS shares[edit]

    See this document for how to change NFS share options: http://docs.sun.com/app/docs/doc/817-6999/6mmbmf9vc?a=view

    Basically, disable the fault monitor, test the change with 'share' update the cluster dfstab file (NOT /etc/dfs/dfstab!), then reenable the fault monitor.
