Problem with PXE Boot over LACP on Aruba Switches

Hello!

I ran into an issue regarding PXE Boot over trunked Interfaces (LACP). A server is connected to a Aruba 5406R zl2 running ArubaOS over 2 interfaces, which are configured into a lacp-trunk and runs fine so far during normal operation. But sometimes the server needs to be reinstalled over PXE. This doesn't work, because during the pxe-boot the server doesn't send LACP BPDUs and therefore the connection doesn't come up. On Juniper-EX Switches there was a solution with the option 'lacp force-up', which enabled one of the trunked interfaces as a single link.

I can't find a solution for this on the Aruba Switches. Any help would be appreciated!
