This section provides drive bay mapping and drive replacement information for Cisco UCS servers running Qumulo Core.
Drive Hot-Swap Support
Qumulo Core supports hot-swapping drives without taking the node offline. When replacing a drive:
- Identify the failed drive using the Qumulo Web UI or CLI.
- Locate the physical drive using the drive bay mapping in the Cisco documentation.
- Remove the failed drive.
- Insert the replacement drive.
- Qumulo Core automatically detects and incorporates the new drive.
Note
For drive replacement procedures, always verify cluster protection status before proceeding. See [Replacing Hardware Components](/cisco-hardware-guide/replacing-hardware-components.html).

Identifying Failed Drives
Using the Qumulo Web UI
- Log in to the Qumulo Web UI.
- Navigate to Cluster > Cluster Overview.
- Click on the affected node.
- View the drive status to identify the failed drive slot.
Using the qq CLI
qq cluster_slots
This command displays the status of all drive slots across the cluster.
Note
Before replacing a drive, verify the serial number of the failed drive matches the serial number reported in the Qumulo Web UI or CLI output. This ensures you remove the correct drive.
