Question 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.

scsetup(1M)						  System Administration Commands					       scsetup(1M)

NAME
scsetup - interactive cluster configuration tool SYNOPSIS
scsetup [-f logfile] DESCRIPTION
Note - Beginning with the Sun Cluster 3.2 release, Sun Cluster software includes an object-oriented command set. Although Sun Cluster software still supports the original command set, Sun Cluster procedural documentation uses only the object-oriented command set. For more infor- mation about the object-oriented command set, see the Intro(1CL) man page. The scsetup command provides the following configuration capabilities, depending on what state the cluster is in when you issue the com- mand: o When you run the scsetup command at post-installation time, the command performs initial setup tasks, such as configuring quorum devices and resetting the installmode property. If you did not use automatic quorum configuration when you created the cluster, run the scsetup command immediately after the cluster is installed. Ensure that all nodes have joined the cluster before you run the scsetup command and reset the installmode property. If you used automatic quorum configuration when you created the cluster, you do not need to run the scsetup command after clus- ter installation. The automatic quorum configuration feature also resets the installmode property of the cluster. o When you run the command during normal cluster operation, the scsetup command provides a menu-driven utility. You can use this utility to perform most ongoing cluster-administration tasks. o When you issue the command from a node that is in noncluster mode, the scsetup utility provides a menu-driven utility for chang- ing and displaying the private IP address range. You must reboot all nodes into noncluster mode before you start this form of the scsetup utility. You can issue the scsetup command from any node in the cluster. You can use this command only in the global zone. OPTIONS
The following options are supported: -f logfile Specifies the name of a log file to which commands can be logged. If you specify this option, most command sets that the scsetup utility generates are run and logged, or only logged, depending on user responses. ATTRIBUTES
