Comparing Cluster Members

Does anyone know of a good utility that will do a binary compare of all the files on two cluster members? We are looking for something we can run on a monthly batch basis to monitor for configuration drift between AIX/HACMP and Solaris/VCS cluster member pairs, use as an ad hoc diagnostic tool when an app runs fine on one cluster node but not the other, or to compare test and prod systems to figure out why a problem cannot be reproduced in the test environment.

I realize tight system management procedures are the best preventative, but when you have eight sysadmins with root (sudo) access and another dozen people with varying access to app directories, some type of drift is inevitable. We need something that can at least help us prove that the machines are identical so we can direct diagnostic efforts back to the application.

sc_zonesd

sc_zonesd(1M)						  System Administration Commands					     sc_zonesd(1M)

NAME

       sc_zonesd - Sun Cluster zone administration daemon

SYNOPSIS

       /usr/cluster/lib/sc/sc_zonesd

DESCRIPTION

       The  sc_zonesd  daemon  is a system daemon that is used by Sun Cluster software to track and manage non-global zones. This daemon initially
       starts when the system comes up.

       The daemon runs in the global zone only.

DIAGNOSTICS

       All diagnostic messages are logged through the syslog function.

NOTES

       The sc_zonesd daemon must be started in superuser mode.

       The sc_zonesd daemon is controlled by the SMF service sc_zones. The cluster software requires this daemon to run for non-global	zone  sup-
       port. If the daemon is killed or if the SMF service is disabled, the cluster node will panic.
