Fabric zoning and LUN security for multiple operating systems
You can connect multiple clusters of various operating systems to the same
switch and fabric using appropriate zoning and LUN security as follows:
• Host zones must contain only homogeneous operating systems.
• Storage port zones may overlap if more than one operating system
needs to share an array port.
• Heterogeneous operating systems may share an XP array port if you
use Secure Manager and set the appropriate host group and mode.
All others must connect to a dedicated XP array port.
• Use Secure Manager for LUN isolation when multiple hosts connect
through a shared array port. Secure Manager provides LUN security
by allowing you to restrict which LUNs each host can access.
