Request for improving pureScale reliability

In this customer environment, there are 4 power740 systems.
Customer use these 4 systems for high availability DB2 pureScale as,

DB node #1 on p740#1

DB node #2 on p740#2

CF node #1 on p740#3

CF node #2 on p740#4

Recently, power740#4 got a PCI backplane hardware issue that cause CF#2 node down and NW connection also lost between DB#2 and CF#2.

Due to the connection problem, DB#2 also gone offline as CF#2 was GPFS cluster manager at this time. The cluster manager exiled DB#2 from GPFS member.
DB#2 instance got offline because it lost GPFS resource.

We think a hardware problem shouldn't cause outage for resources on the other hardware.

Customer request us to improve pureScale system reliability.
