Disk Zoning Policies

You can assign disk drives to the server nodes using disk zoning. Disk zoning can be performed on the
controllers in the same server or on the controllers on different servers. Disk ownership can be one of the
following:
Unassigned
Dedicated
Note
Shared
Note
Chassis Global Hot Spare
Important Disk migration and claiming orphan LUNs: To migrate a disk zoned to a server (Server 1) to another server
(Server 2), you must mark the virtual drive (LUN) as transport ready or perform a hide virtual drive operation.
You can then change the disk zoning policy assigned for that disk. For more information on virtual drive
management, see the Disk Groups and Disk Configuration Policies section of the
Management

Creating a Disk Zoning Policy

Procedure
Step 1
Unassigned disks are those not visible to the server nodes.
If this option is selected, you will need to set the values for the Server and Controller for the disk slot.
A disk is visible only to the assigned controller.
Shared disks are those assigned to more than one controller. They are specifically used when the servers
are running in a cluster configuration, and each server has its storage controllers in HBA mode.
Shared mode cannot be used under certain conditions when dual HBA controllers are used.
If this option is selected, you will need to set the value for the Slot Range for the disk.
