Thank you, Jim.

I just wanted to be sure IBM was remaining open.

Scott:

And you won't see any mention of STK or EMC or HDS disk anywhere in the
publications, not just related to the SCSI FCP support. It is up to vendors
to certify their products for attachment. However, to answer your first
question, there is nothing in the code to restrict this to ESS. This is the
only disk device that IBM Storage Systems was willing to certify in this
environment.
