Cluster communication issue

UNIX AIX
1

Hi,

I am using Power HA7.1.1 SP5 AIx 7.1

My both cluster nodes are independently working. RG informations are not updating each other. Node A shows that node B is down and vice versa.

RG1 is running node A, RG2 running on node B.

=== clRGinfo From Node B ===
RG01               OFFLINE                      NODE-A
                      OFFLINE                      NODE-B

RG02_Sapvg     ONLINE                       NODE-B
                      OFFLINE                      NODE-A
=== clRGinfo from Node A===

RG01        ONLINE                       NODE-A
               OFFLINE                      NODE-B

RG02        OFFLINE                      NODE-B
               OFFLINE                      NODE-A

====clstat output from node B====

           Interface: NODE-A_B (0)           Address: 10.x.x.x
                                                State:   DOWN

====clstat output from node A ====

  Node: NODE-B		State: DOWN
  Node: NODE-A  	State: UP

========================
I have done cluster verification and sync. No error was triggered on that and it completed normally. i have stop and started the cluster services but same issue.

What does a clmgr sy cl say?

There are so many possible causes that without further information it is virtually impossible to guess. Do an "Extended Verification and Synchronization" and post the results here.

I hope this helps.
