Disk Sharing for High Availability
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
Unassigned disks are those not visible to the server nodes.
Dedicated
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.
Note
Shared
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.
Note

If this option is selected, you will need to set the value for the Slot Range for the disk.
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 Cisco UCS Manager Storage
Management Guide.
