Script Execution details
The script will specifically work for Linux Standalone
server. It is a menu based system providing us with 3
options namely Pre-Checks, Post-Checks and Compare_Pre_Post.
Both Pre-Checks and Post-Checks will generate files related
to the configurations within the server and place it into a folder that is
provided as per the script
Pre-Checks option will be selected before the start of data
migration activity to capture configuration details of the Linux machine which
will be used at a later stage. Once the storage activity is completed, we will
run second option which is Post-checks.
The 3rd option (Compare_Pre_Post) will be used to
verify if there are any changes in the configurations or command outputs. This
will help us in identifying details requiring our attention for further
troubleshooting.
Script
#!/usr/bin/env python
# Purpose :
To Collect information from the server before and after migration
activity.
# To compare pre and post
migration information for any discrepancies.
# Author :
Sri Krishna Chirumarri
# Version :
1.6
# Details :
This is a menu based script that will ask you to enter your choice of
preference.
# Execution :
Interactive Menu to choose your option for the respective activity
