Exercise 6: Failover Testing - Solution
|
|
This script demonstrates how to perform a failover test on a VPG.
|
|
|
|
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 failover.py --vpg-name "My-VPG"
|
|
|
|
This solution demonstrates:
|
|
- Finding a VPG by name
|
|
- Starting a failover test with default settings
|
|
- Monitoring test progress
|
|
- Stopping the test when requested
