The arbitrated loop topology is not supported by the Tru64 UNIX
or TruCluster Server products.
When support for Fibre Channel arbitrated loop is announced in
the TruCluster Server Software Product Description (SPD), the
technical update version of this information will be modified to
include arbitrated loop. The SPD will provide a pointer to the
technical update.
