Red Hat High-Availability Clustering without SAN, HP MSA 2052 Storage

Hello,
I"m trying to configure budget saving HA clustering for Oracle.
The idea is to get rid of 2 SAN switches, but directly attach FC HBA connection from servers to HP MSA 2052 storage.

Basically, I have following and please check the attached image of layout. Will this work?

Servers:
1 pair of HP servers for WAS, each server has single dual FC HBA card
1 pair of HP servers for Oracle DB, each server has single dual FC HBA card
1 HP MSA storage with 5TB. It will host two datastores, Oracle DB and WAS data. It also has redundant controllers, each controller has 4 FC HBA ports.

Wit this setup, will I be able to configure RHEL clustering Active-Passive for Oracle DB?
Will there be any issue sharing LUN between the server pairs and failover?
