You had 2 failures. No real way to design around that.
GAB "visible" would prevent bad things from occurring.

Subject: [Veritas-ha] LLT heartbeat redundancy

Hi,

As far as I understand the manuals, the LLT heartbeat links should be
isolated 
from each other. Now, consider the following scenario  - Node1 is
connected 
with two links, each one to a sperate switch. We will call them 
li...@node1@sw1 and li...@node1@sw2.
Node4 is also connected with 2 links: li...@node4@sw1 and
li...@node4@sw2.

Now, if Node1 lose li...@node1@sw1 and Node4 lose li...@node4@sw2, they
can no 
longer see each other, although they still have a valid heartbeat link.

Am I missing something? Is there a way around this issue?
