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

Chassis Global Hot Spare

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
