Sharing the IBM Enterprise Storage Server between a host and the SAN Volume Controller

The following restrictions apply when you share the IBM Enterprise Storage Server between a host and a SAN Volume Controller:

• If an IBM Enterprise Storage Server port is in the same zone as a SAN Volume Controller port, do not put that same IBM Enterprise Storage Server port in the same zone as another host.
• A single host can have both IBM Enterprise Storage Server direct-attached and SAN Volume Controller virtualized disks that are configured to it.
• If a LUN is managed by the SAN Volume Controller, it cannot be mapped to another host.
