I would ask what type of hardware is your SAN?  I am running on 2 DMX3000
Storage Arrays by EMC.  We share the box but not the disks with the open
system folks.  They have the SAN stuff.

One storage array is the primary DASD that we normally run off of.  The
second is populated by EMC's Replication process and therefore all of the
SYSRES data is constantly being updated on the second Storage Array incase
the primary array fails.  If it does, the EMC software will "swap" us up to
the replicated string and we are still running.  Coming back is more fun, as
we use the Autoswap software to do that.

We are always on Mainframe dasd never SAN.  And as RS pointed out, the
mainframe does not use SAN.  We live on a DMX where SAN and mainframe share
the box but not the disks.
