Compare_report

The compare_report command is a very useful utility to compare the software installed on two systems, for example for making sure the same software is installed on two nodes of a PowerHA cluster.

First, create the necessary reports: 

# ssh node2 "lslpp -Lc" > /tmp/node2
# lslpp -Lc > /tmp/node1
Next, generate the report. There are four interesting options: -l, -h, -m and -n:
  • -l   Generates a report of base system installed software that is at a lower level.
  • -h   Generates a report of base system installed software that is at a higher level.
  • -m   Generates a report of filesets not installed on the other system.
  • -n   Generates a report of filesets not installed on the base system.
For example: 
# compare_report -b /tmp/node1 -o /tmp/node2 -l
#(baselower.rpt)
#Base System Installed Software that is at a lower level
#Fileset_Name:Base_Level:Other_Level
