Exercise 5: VPG Operations - Solution (Part 1: VPG Creation)
|
||||
This script demonstrates how to create and configure VPGs in your Zerto environment.
|
||||
|
||||
Prerequisites:
|
||||
1. Install the zvml package in development mode:
|
||||
cd /path/to/zvml-python-sdk
|
||||
pip install -e .
|
||||
2. Update prerequisites/config.py with your ZVM details
|
||||
|
||||
This solution demonstrates:
|
||||
- Creating a new VPG with basic settings
|
||||
- Configuring journal, recovery, and network settings
|
||||
- Adding VMs to the VPG
|
||||
- Proper error handling and logging
