Troubleshooting Boot Errors

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: Swarm Storage 15.3.1 Release

These symptoms could indicate a hardware compatibility issue with the hardware. Contact DataCore Support with the details of the hardware setup.
