The following list summarizes information about SANMAN:
SANMAN can be run in any processor. The process pair must be configured to be
started by the persistence manager. You add the ServerNet SAN manager process as
a generic process using the SCF Kernel subsystem ADD PROCESS command. This
task is described in Section 3, Installing and Configuring a ServerNet Cluster. See the
SCF Reference Manual for the Kernel Subsystem for complete command syntax for
the ADD PROCESS command.
As an alternative, you can use the ZPMCONF macro to automate the process of
adding MSGMON, SANMAN, and SNETMON to the system-configuration database.
For a description of the macro, refer to Appendix E, TACL Macro for Configuring
MSGMON, SANMAN, and SNETMON.
The ServerNet SAN manager process must be configured:
•
To be persistent (set the AUTORESTART attribute to a nonzero value).
•
To have the process name $ZZSMN (set the NAME attribute to $ZZSMN). The
recommended symbolic name is ZZSMN.
•
So that the $ZPM persistence manager stops the process by sending in an internal
system message (set the STOPMODE attribute to SYSMSG).
•
To run under the super group user ID (by default the USERID attribute is set to the
user ID of the current SCF session).
•
To have at least two processors (preferably more) in the CPU list (defined with the
CPU attribute).

The Expand subsystem is the networking software that connects NonStop S-series
servers and other NonStop servers. It extends the operation of the fault-tolerant
operating system to dispersed nodes.
In an Expand network, system resources can communicate with one another as if they
were running on the same local system. This communication is achieved by using the
NonStop Kernel message system as the common interface to access system
resources.
