Cluster attached storage to linux .... anyone? HP MSA 1000 forexample.

[Ansar Mohammed]

Yup, its not really rocket science. 
I used to work with an EVA and RHEL.

Just install the HBA drivers. If you are using multipathing but you don't
have multipathing aware software you may be limited to only one path to the
SAN, or you may risk data corruption.
