On the contrary.  They can all be connected to the SAN.

You need to look at either a Modular Data Router (MDR) or a Network
Storage Router (NSR).  These are both devices that allow (just about)
any SCSI device to attach to a SAN.  Both are fully supported in
OpenVMS.  The MDR has interfaces available for both HVD and LVD SCSI
buses.  The NSR has LVD interfaces (I don't remember if it supports an
HVD bus, even though I have one sitting in the other room).

Both are available on the used market (eBay, Island, PSDS, and
others).  I believe the NSR is still available new from HP.

I have one client using an MDR to connect both a TZ877 DLT loader and
an HP LTO 1 Autoloader to their SAN.  Another clients uses an MDR to
connect a TL891 and IBM LTO drive to their SAN.  Works like a charm.
Fully supported in a cluster too.  If you have multiple, non-clustered
systems attached to the same SAN then you would have to manually
prevent simultaneous access to the drives from multiple systems.  Just
like any other non-clustered systems.
