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.

scconf_transp_adap_sci(1M) System Administration Commands scconf_transp_adap_sci(1M)
NAME
scconf_transp_adap_sci - configure the sci cluster transport adapter
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.
You can configure sci SCI-PCI adapters as cluster transport adapters. These adapters can be used with the dlpi transport type.
The adapter name is sciN, for example, sci0. Do not use scidN as the adapter name.
An sci adapter can only be connected to another sci adapter or to an SCI switch. When an sci adapter is connected to an SCI switch, it is
important that you specify the correct port name when referring to a port on the switch as an endpoint argument to the scconf or scinstall
utility. The port name must match the port number on the SCI switch (the number that is printed on the switch itself). Failure to give the
correct port name could result in the operation failing. The result of providing an incorrect port name will be the same as you would see
if the cable between the adapter and the switch were removed.
There are no user-configurable properties for cluster transport adapters of this type.
