Create FlashCopy relationship — Select target volumes for the 1:n relationships

Use this page to select target volumes for multiple FlashCopy^® relationships.

Introduction

If you selected a FlashCopy relationship type that included a single source with multiple targets (this is known as multiple relationship FlashCopy), you can select a maximum of 12 (hence 1:n) target volumes for each source volume. This page repeats for each source volume that you selected. That is, each time through the wizard, you can create multiple 1:12 relationships.

Fields

Select by resource type

The type of resource (LSS, Volume group, Host attachment, Show all volumes) from which to select target volumes. The type of resource that defaults corresponds to the selection that you made on the select source volumes page.

Specify (LSS, Volume group, Host attachment, Storage type)

The type of resource (LSS, Volume group, Host attachment, storage type) from which to select target volumes. The type of resource that defaults corresponds to the selection that you made on the select source volumes page.

Select target volumes

The storage type of the target volumes must be the same as that of the source volumes. That is, both must be either fixed block (FB) or count key data (CKD).

Consider the following guidelines when you select target volumes:

The size of the target volume must be at least as large as the source volume that you selected.
The storage type of volume that you select for the target volumes must be the same as the source volumes. That is, the target volumes must be the same type of format: fixed block or count key data as the source volumes.
Target volumes that are already involved in other FlashCopy relationships are not eligible volumes for selection.

OK

Reads and stores the current selection and takes you to the next step of the wizard.

Note: If you used the < Back button in the wizard to arrive at this page, the previous selection remains in effect. If you then change the selection and click the OK button, the current selection replaces the previous selection and takes you to the next step of the wizard.

Cancel

Ends the wizard and returns you to the main page without completing the task.
