Will the following SAN setup work? Storage controller A is disk array 1 and Storage controller B is disk array 2 however...

When I disconnect the fiber cable from the switch to storage controller A, I can no longer see disk array 1 from the OS.  The zoning is setup identical on both switches and I believe it's correct.

From the PDF I've attached, will this cabling work or do I need to run ANOTHER fiber cable from each switch to the opposite storage controller to provide for redundancy?

Fiber Storage Enclosure is a IBM 4100, switches are IBM 2005-H08 (like a Brocade 3250 8 Port)

Both controllers should be connected to both switches so you do need 2 more cables normally but IBM's documentation is very strange. http://www.redbooks.ibm.com/redbooks/pdfs/sg246363.pdf - I would wire it as per fig 3.14 but some of the other examples show both controller host ports going to the same switch.
