ACU don't see MSA1000 controller

Hello everybody!

I have a such problem:

When I launch HP ACU, I can see only internal controller...

About my hardware:

I have two servers DL580G3 with HBA adapters, they connected with two storage systems MSA1000 (throught SAN switches). This scheme is attached to this message.

Some time ago this cluster has RHEL 4 update 4 installed on, and ACU was working properly, it detects the both controllers (internat and external) from the both nodes.

I install RHEL 4 update 8, and now ACU from fisrt node work properly, but from the second node detects only internal controller.

I tried to install other versions of ACU to the second node, but situation is the same.

I don't understand what is the reason of this problem, because the both nodes has the same version of RHEL and ACU, but only one of them detects external controller(MSA1000) from ACU.
The operation system works with MSA1000 storage properly, I'm using multipath and can see the alll path avialable, but onle ACU don't want to work ...

Sorry for my bad English.
