Explanation:
Boot Load Failed
If the AI client starts downloading the boot_archive, but then fails with the error, “Boot load failed,”
that indicates that the client DHCP information is configured incorrectly.
Rebooting with command: boot net:dhcp – install
Boot device: /pci@7c0/pci@0/network@4:dhcp File and args:
1000 Mbps FDX Link up
HTTP: Bad Response: 500 Internal Server Error
Evaluating:
Boot load failed
This error could happen if another DHCP server is responding to the client. Check the DHCP
configuration for this client. If the configuration appears to be correct, determine whether there is
another DHCP server in the subnet.
