Sharing the IBM ESS between a host and a system

The IBM Enterprise Storage Server (ESS) can be shared between a host and a system.

The following restrictions apply when you share the IBM ESS between a host and a system:
  • If an IBM ESS port is in the same zone as a system port, that same IBM ESS port should not be in the same zone as another host.
  • A single host can have both IBM ESS direct-attached and system virtualized disks that are configured to it.
  • If a LUN is managed by the system, it cannot be mapped to another host.
