We had a cluster service 'lost' for several minutes yesterday
(& this is a repeat incident): refer to attached screens.

Q1:
What could be the cause of the issue?

Q2:
Any resolution or workaround for this issue?

Q3:
Currently the heartbeat goes thru Production network.
Will setting up dedicated heartbeat (ie a direct cross-
cable between the 2 member servers of the cluster
resolve this?

Q4:
Or can we tune/tweak the heartbeat interval & the number
of missed heartbeat to make the cluster more resilient
ie to address this issue?  If so, can point me to a link or
provide instructions on how to tune these?

Q5:
Can this be due to differences in the various firmware
(UEFI, versions between the 2 member servers as IBM
found the versions to be different but can't pinpoint that
this issue is due to differences in firmware version of
the member nodes.

I prefer not to attach the Event Viewer logs here as it
contains sensitive info
