Exercise 4: Resource Discovery - Beginner-Friendly Instructions
|
|
This script demonstrates how to discover and work with resources in your Zerto environment.
|
|
|
|
PREREQUISITES (Complete these first):
|
|
1. ✅ Completed Exercise 3 (Site Discovery)
|
|
2. ✅ Make sure you have the zvml package installed
|
|
3. ✅ Updated prerequisites/config.py with your ZVM details
|
|
|
|
WHAT YOU NEED TO DO:
|
|
In this exercise, you will:
|
|
1. Create a ZVMLClient to connect to your ZVM (same as previous exercises)
|
|
2. Get a list of all available sites
|
|
3. Identify your local site and a peer site
|
|
4. Discover different types of resources:
|
|
- Local site: Virtual Machines (VMs)
|
|
- Peer site: Datastores, Hosts, Folders, Networks
|
|
|
|
STEP-BY-STEP INSTRUCTIONS:
|
|
1. Look at the TODO comments below - they tell you exactly what to do
|
|
2. Replace the placeholder code with the actual code
|
|
3. Each step has hints and examples to help you
|
|
4. If you get stuck, check the solution file in the solution/ directory
|
|
|
|
WHAT ARE RESOURCES?
|
|
- **VMs**: Virtual machines that can be protected/replicated
|
|
- **Datastores**: Storage locations where VMs are stored
|
|
- **Hosts**: Physical servers that run the VMs
|
|
- **Folders**: Organizational containers for VMs
|
|
- **Networks**: Network connections for VMs
|
|
- **Local Site**: Your current ZVM location
|
|
- **Peer Site**: Another location you can replicate to/from
