[ironic] Failed when writing image to the device file /dev/sda

Hi all,

I have been exploring ironic, with a simple setup. However, I get the following error messages whenever I attempt to deploy an ISO image to my baremetal node.

1. An agent token generation request is being refused as one is already present for the node 2. Writing image to device /dev/sda failed with exit code 32. stdout: . stderr: lsblk: /dev/sda2: not a block device 3. Invalid or missing agent_token received for node

I am not quite sure what is required to be set on my node's property other than vendor and cpu_arch. Any help would be appreciated.

Best, James
