HP Lefthand Multisite cluster

I have two sites site A and site S.

Site A has Nodes 1 and 2 and Site S has Nodes 2 and 3.
The four nodes are part of a multisite cluster.

Nodes 1 and 2 are on subnet 172.16.123.0/24 (Primary)
Nodes 2 and 4 are on subnet 172.16.124.0/24
FOM is also on 172.16.123.0/24

When perfroming tests like taking one node down at a time all works fine, also if i take two nodes down which means a site is down all works fine and by this i mean that the storage volumes presented are still accessable, once reconnected all syncronizes and is back to normal.

I only experaince problems when i bring a Node down from each site at the same time..the volumes are lost and marked as Not Availabile. (Please see attached)

Any ideas?

What was the answer? Move the FOM to a 3rd subnet?
