Before to connect the HDS Storage to AIX, yo need install the ODM FIleset.
HDS provide 2 types of ODM, the first to work with native AIX MPIO, the second to work with HDLM software.
You need install only one of ODM types.
You need review with HDS professional services, the correct flags in the Hostgroup, you need the correct flags to avoid reservation conflicts betwen the cluster nodes.
After to made the zonning and assing the LUNS, if you AIX servers use HDLM, install the software.
at finish you need adjust the mqueue and rw_timeout values for each LUN,
In the cluster scenario probably you need set the "reserved" flags for each LUN in the aix enviroment
Probably you need adjust many parameters in cluster enviroment.
I recommend that you read the "Hitachi HDLM AIX users guide", to review all this themes.
