CLuster for realtime

The Question is: 

    Where can I find information about design considerations for a VAX
    Cluster using DSSI disk sharing?  I am designing a real-time system
    which is operational 24x7 and need to know information like, what
    happens if a cluster member crashes (loses power, etc. ), how will
    other members be affected, how fast is the cluster reconfigured?My plan
    is to cluster 2 VAX 4x00 and 2 DSSI storage devices as well as several
    (up to 30) workstations.  The workstations are being clustered for
    convenience only.  The 2 VAX 4x00

The Answer is: 

    Clustering is not recommanded for realtime systems.  You need to
    consult the "DSSI Vaxcluster Installation and Troubleshooting Guide"
    order number EK-410AA-MG.  It is an older manual, that does not include
    newer DSSI adapters.  You can also consult "VMScluster Systems
    for OpenVMS" AA-PV5WB-TK.
