Hi
Yes. You need to install latest available support for HBA adapters and the latest available firmware for your HBA adapter. The same way you have to install the recommended firmware for DS4400 storage subsystem (please check the compatibility matrix on ibm.com).
No matter if you don't have more than one HBA you should install the rdac support.
Hope this helps
