Exercise 5: VPG Operations - VPG Creation
|
||||
This script demonstrates how to create and configure a VPG.
|
||||
Exercise 5: VPG Operations - Template
|
||||
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
|
||||
|
||||
Usage:
|
||||
python create_vpg.py --vm-names "vm1" "vm2" "vm3" [--vpg-name "My-VPG"]
|
||||
|
||||
Your task:
|
||||
1. Implement the find_vms_by_names function to locate VMs by their names
|
||||
2. Complete the VPG configuration with appropriate settings
|
||||
3. Add the found VMs to the VPG
|
||||
4. Implement VM removal functionality
|
||||
|
||||
The script should:
|
||||
- Create a new VPG with basic settings
|
||||
- Configure journal, recovery, and network settings
|
||||
- Add specified VMs to the VPG
|
||||
- Allow removing VMs from the VPG
