When booting, the node generates an error stating

a boot device is

unavailable.

The node boots into an operating system other than Swarm.

Verify the node is capable of booting from a USB device and the USB memory device is configured as the primary boot device if booting from a USB device.

Verify the following if PXE booting

:

• The server is configured to network boot.

• PortFast is configured on the switch ports

• leading to the Swarm node.
  

• 
  The extended time delay required for listening and learning Spanning Tree states can prevent netboot from delivering the Swarm image to the node in a timely manner if the above are not satisfied.

The node boots from the USB device/ CSN/ or custom PXE boot server, but Swarm fails to start.

The node begins to boot but reports a "kernel panic" error and stops.

If using a CSN or custom PXE boot server, update the ramdisk size as mentioned at the bottom of this page: https://perifery.atlassian.net/wiki/spaces/public/pages/3298918413/Swarm+Storage+15.3.1+Release%E2%80%8B%E2%80%8B%E2%80%8B%E2%80%8B%E2%80%8B%E2%80%8B%E2%80%8BACE

These symptoms

could indicate a hardware compatibility issue with the hardware. Contact

DataCore Support with the details of
