HPE 5406zl (J9642A), DT-LACP & pxe (split-LACP szenario)

[wtmkr]

Hello all,

i've got a problem with a 5406zl "Cluster" and hope that one of you can give me the final hint to solve my Problem. Unforteunatly i did not find anything in the www :/

We've got two 5406zl (K.16.02.0025). On both Switches is a Switch-Interconnect established to each other and all is working fine except in a Split-LACP szenario (e.g. PXE-Boot).

Trk25-Trk32 is a Database Cluster where the first Server is a DHCP/TFTP-Server and the last seven are "PXE-Clients". The seven DB-Nodes are only bootet via PXE - they don't have a own OS on Disk.

If both Ports are activated, the PXE-Client isn't able to bootstrap the OS. In the DHCP-Logs i can see a DHCP-Discover and the offer from the Server - thats it - not more. If i disable one, of both interfaces, than the PXE-Boot is successful. So i assume that dt-lacp isn't actually able to put both interfaces in a type of fallback-mode.

Is this a limitation of DT-Trunking or did i forget something to configure?

Config switch-1 (switch-2 is equivalent)

Hi all,

is this szenario really that uncommon that no one has a little hint?

Greetings Matthias
