Exercise 4: Resource Discovery - Solution
|
|
This script demonstrates how to discover and work with resources 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:
|
|
- Discovering local site resources (clusters, hosts, datastores)
|
|
- Working with peer site resources
|
|
- Proper error handling and logging
