Rafael,
multipath.conf seems to be correct as per HPE guide.
I have few queries:
1. Do we have volumes created under each controller ?
The preferred data path for controller A owned volume would be controller A host ports.
Similarly, The preferred data path for controller B owned volume would be controller B host ports.
2. If there are different volumes under controller A and controller B, are the hard drives used in each volume of the same type ?
ex: 10K SAS, 15K SAS)
