Upgrading a Common Disk to a HyperMetro Disk

Prerequisites

The HyperMetro DESS device contains a common disk that is in the Available state.

Context

• Common disks and HyperMetro disks can be created on HyperMetro DESS devices. A HyperMetro disk pair consists of a preferred disk and a non-preferred disk, which are located on the two associated DESS devices in a HyperMetro resource.
• A common disk can be upgraded to a HyperMetro disk. After the disk is upgraded to a HyperMetro disk, the disk becomes a preferred disk. The system automatically generates a non-preferred disk.

Procedure

1. Log in to the management console. For details, see Logging In to the Management Console.

2. Click and select the wanted region.

     2. In the row of the desired DESS device, click the number in the Number of Disks column to go to the Disks tab page.
        

        The device is the HyperMetro DESS device. If HyperMetro is enabled, it is a HyperMetro DESS device array.
