Description
Error Message
The following error can be seen in the VCS engine_A.log:
VCS WARNING V-16-10011-5611 (
Resource is OFFLINE.
Cause
It is a known AIX issue and it was first reported in AIX 6.1 environments but also affects to AIX 5.3.
There is a bug in AIX where, a bind to a newly opened AF_NDD socket fails with a EEXIST (already bound) error. This failure is random and because of this, the VCS haping binary, used by the VCS NIC to ping the NIC resource, sometimes fails as it cannot bind the socket.
Resolution
The bug has been fixed for AIX 6.1 in the IZ76058 patch. Customer should check with IBM for availability and other AIX versions and install the patch.
Applies To
This is only applicable to VCS running over AIX with VIO Server network interfaces.
