Using the StoreOnce CLI
1. Run the StoreOnce CLI command:
hardware show problems
This will display warnings for all hardware components and, in our example, assist in identifying
the RAID controller and component that is causing a problem.
2. To drill down to the hardware component causing the problem run the StoreOnce CLI command:
hardware show status <Dev-id>
# hardware show status
