Sometime ago, in my contribution to another thread, I uploaded an EMC (copyright acknowledged) document detailing their storage use with Solaris. Although the context of this was iSCSI, this document covers SCSI and FC SAN's too.
Find the pdf attached to this thread:
Iscsiadm issue
You don't say the model of your EMC storage but the document covers most things.
Heavy reading but I hope it helps. (Perhaps not).
