12 Node cluster abend.
All member nodes of the cluster experienced an abend at the same time.
In the abend.log file it shows the following entry: Abend 1 on P00: Server-5.70.05-0: VLL: VllInvokeCallbacks() called with empty bitmasks
TheEIP of this abend is in CLSTRLIB.NLM

This happend just after a node tried to join the cluster. The attempt to join the cluster failed with a fatal SBD error.


Make sure that the HBA card(s) is inserted properly in the slot on the server mainboard.
In one of the nodes the HBA card was not inserted properly, it was halfway in the slot.
This caused a chain reaction throughout the cluster when this node tried to join the cluster and access the SBD partition.

Additional Information

The VllInvokeCallbacks is a function in the VLL.NLM module. This module is an infrastructure that integrates GIPC and SBD and provides an application programming interface (API) according to the VI Architecture industry standard, which is the standard for high-performance cluster communication.VLL is also responsible for handling node join and leave by coordinating with other cluster modules.
