RAID CONTROLLER PROBLEM

[machaya chivaviro_2]

have an rp4440 HP9000 running HP-UX 11.1.
My problem is that when I try to connect the disks to the RAID controller the system freezes. But this does not happen on the other controller. How can I solve this problem.
Please help.
Here is the hardware path and driver information.

Hi,

what is your disk device (MSA?)?

Did you try to connect the cable while the system is running?
