红帽全球峰会25.2. Disks are not detected
If the installation program cannot find a writable storage device to install to, it returns the following error message in the Installation Destination window: No disks detected. Please shut down the computer, connect at least one disk, and restart to complete installation.
Check the following items:
- Your system has at least one storage device attached.
- If your system uses a hardware RAID controller; verify that the controller is properly configured and working as expected. See your controller’s documentation for instructions.
- If you are installing into one or more iSCSI devices and there is no local storage present on the system, verify that all required LUNs are presented to the appropriate Host Bus Adapter (HBA).
If the error message is still displayed after rebooting the system and starting the installation process, the installation program failed to detect the storage. In many cases the error message is a result of attempting to install on an iSCSI device that is not recognized by the installation program.
In this scenario, you must perform a driver update before starting the installation. Check your hardware vendor’s website to determine if a driver update is available.
For more general information about driver updates, see the Updating drivers during installation.
