The operating system of the DPU identified in the message is not ready for normal function because either the boot synchronization period has timed out or the boot synchronization timeout value is too less.

Increase the DPUOSReadyTimeout value based on your DPU configuration. If the issue persists, reinstall the DPU operating system and power on the server.

1.Follow the steps below to verify the DPU connectivity, and note down  the slot number:

2. Follow the steps below to verify DPU attributes are correctly configured:  
#ssh username@hostname-idrac or username@<iDrac_IP>
racadm>>get system.pcislot.<slot_num>.DPUTrust
[Key=system.Embedded.1#PCISlot.2]
DPUTrust=Enabled
racadm>>get system.pcislot.<slot_num>.DPUBootSynchronization
[Key=system.Embedded.1#PCISlot.2]
DPUBootSynchronization=Enabled

If anyone of them is disabled, enable it, like below:
racadm>>set system.pcislot.<slot_num>.DPUTrust 1
[Key=system.Embedded.1#PCISlot.2]
Object value modified successfully
racadm>>set system.pcislot.<slot_num>.DPUBootSynchronization 1
[Key=system.Embedded.1#PCISlot.2]
Object value modified successfully

3. Follow the steps below to check the current boot synchronization timeout value:
racadm>>get system.pcislot.<slot_num>.DPUOSReadyTimeout
[Key=system.Embedded.1#PCISlot.2]
DPUOSReadyTimeout=10

It can be increased like below:
racadm>>set system.pcislot.<slot_num>.DPUOSReadyTimeout 20
