Create Metro Mirror relationship — Select target volumes (manual pairing)

Use this page to select target volumes to participate in Metro Mirror relationships. The target volumes at your recovery (or remote) site receive updates that are written to the source volumes at the production (or local) site.

Introduction

This page displays only if you selected the Manual volume pair assignment option when you selected the method for selecting volume pairs. You have to assign to each source volume a target volume, one after the other. You have to repeat the process for each selected source volume.

Fields

Storage complex

The nicknames of storage complexes that are available for selection. If you want to use target volumes from another storage complex, you can specify a different storage complex (and storage unit and LSS, for example) from which to select target volumes.

A storage complex describes a group of storage units such as the DS6000™ that is managed by a single management console.

Note: Nicknames are user-specified when resources are created and can be used as part of an overall scheme or naming convention for making resources easier to identify and manage.

Storage unit

The nicknames of storage units that are available for selection. This list can include any nickname that is associated with any 2107, 1750, and 2105 Model 800 currently displayed in the Storage units main page. A storage unit consists of a single DS6000.

Resource type

The type of resource (LSS, Host, Volume group, Show All Volumes) from which to select volumes for remote mirror and copy functions. The value of the selection in this field determines the field that is displayed to the right of this field. The default value for Resource type is LSS. The following resource type values and the respective field names are displayed:

For LSS: Specify LSS
For Host: Specify Host attachment
For Volume Group: Specify Volume group
For Show All Volumes: Specify Storage type

Specify LSS

The list of LSS identifiers that are available for selection. An LSS is a group of up to 256 logical volumes that have the same disk format, either count key data (CKD) for zSeries environments, or fixed block (FB) for open-system environments.

Specify Host attachment

The list of host attachment identifiers that are available for selection. A host attachment identifies the type of interface, such as Fibre Channel Arbitrated Loop (FC-AL), that is used to connect open-systems and zSeries hosts to invoke and manage remote mirror and copy functions.

Specify Volume group

The list of volume groups that are available for selection. A volume group, specified as a nickname, is a collection of logical volumes.

Show All volumes

"All FB Volumes" or "All CKD Volumes" that are available for selection. If "None selected" is selected, the table is empty.

For the zSeries^® environments, the data that is stored in a storage unit is arranged in a count-key-data (CKD) format. For the open system environments, the data that is stored in the storage unit is arranged in a fixed-block (FB) format.
