NOTE: The disks in a head server unit are different to those in the expansion shelf. Be sure to
order the correct replacement disk.
The following example shows the Hardware tree expanded to show the disk failure in a disk

Using the StoreOnce CLI
The following StoreOnce CLI commands can also be used to identify hardware problems and to
walk through the hardware tree to obtain more details about a specific component.
• hardware show problems
• hardware show status <Dev-id>
The following example illustrates how to use the StoreOnce CLI commands to find out more about
the disk failures we have identified on the StoreOnce GUI.
1. Run the StoreOnce CLI command:
hardware show problems
This will display warnings for all hardware components and assist you in identifying the storage
cluster 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
