23.2 Grid Configuration Basics

23.2.1 Peer Configuration Overview

In the simplest case, establishing a peer relationship can be accomplished with as few as two configuration lines: one line to indicate how to contact the peer and one line to indicate how to authenticate the server. However, data migration issues, credential mapping, and usage policies must often be addressed in order to make a peer-based grid effective.

To address these issues Moab provides facilities to control how peers inter-operate, enabling full autonomy over both client and server ends of the peer relationship.

23.2.2 Initial Configuration

At a minimum, only two parameters must be specified to establish a peer relationship: RMCFG and CLIENTCFG[<X>].  RMCFG allows a site to specify interface information directing Moab on how to contact and inter-operate with the peer. For peer interfaces, a few guidelines must be followed with the RMCFG parameter:

# moab.cfg on MoabServer01

SCHEDCFG[MoabServer01] MODE=NORMAL SERVER=hpc-01:41111
RMCFG[MoabServer02]    TYPE=moab   SERVER=hpc-02:40559

Configuring the CLIENTCFG parameter is mandatory. When specifying the CLIENTCFG parameter for peers, the following guidelines must be followed:

# moab-private.cfg on MoabServer01

CLIENTCFG[RM:MoabServer02] KEY=3esfv0=32re2-tdbne
# moab-private.cfg on MoabServer02

CLIENTCFG[RM:MoabServer01] KEY=3esfv0=32re2-tdbne AUTH=admin1
