See the VMS VAXcluster Manual, the Guide to DECnet–VAX Networking,
and the VMS Networking Manual for information on setting up systems
as members of complex networks and setting up remote printer and batch
processing queues.
A.2.3.1 Configuring for Dual-Host Systems
The VMS Installation and Operations manual tells you how to configure
a dual-host system for cluster operation. You can set up the system for
operation as a:
• Pair of boot servers for a new local area cluster to which you intend to
add satellites
• Two-node cluster to which you do not intend to add satellites
• Pair of boot servers that you want to add to an existing cluster
NOTE: You must assign the same allocation class to both systems and to the
ISEs. The allocation class must be different from that of other systems and
hierarchical storage controllers (HSCs) in a cluster. Refer to your system
Operation manual for information on setting parameters for ISEs.
The following software licenses are required to configure a dual-host system.

A.2.3.2 Checking Your Modification Work
You can use two commands to check your work after you modify FIS for a
dual-host system.
• Use SHOW DEVICE D to list the ISEs. Make sure the number of ISEs
listed matches the number in your dual-host system.
Too many ISEs indicates an incorrect allocation class setting for an
ISE.
Too few ISEs indicates an incorrect unit number for an ISE.
• Use SHOW DEVICE DI/FULL to check that the alternate host name
for your dual-host system is displayed.
