Create Metro Mirror relationship — Verification

Introduction

After you create Metro Mirror relationships and select copy options for the volume pairs that are participating in these relationships, the information that is displayed on this page allows you to verify your selections. After you click the Finish button, a relationship is created between the source and target volume and the copy options are enabled for the volumes that you have selected.

Fields

Source Nickname

The nickname of the source volume that is used when the volume pair is created.

Source Number

The volume number of the source volume that is used when the volume pair is created.

Source Storage Complex

The nickname of the storage complex from which the source volumes for this relationship are selected.

Source Binary GB

The size, in gigabytes, of the selected DS source volume for the specified relationship. The DS volumes are configured in binary format, where 1 GB (2³⁰) = 1 073 741 824 bytes.

Source Decimal GB

The size, in gigabytes, of the selected ESS source volume for the specified relationship. The ESS volumes are configured in decimal format, where 1 GB (10⁹) = 1 000 000 000 bytes.

Target Nickname

The nickname of the target volume that will be used when the volume pair is created. If the target volume is a 2105 volume, Not applicable displays in place of the nickname.

Target Number

The volume number of the target volume that is used when the volume pair is selected. This is the storage unit serial number that is combined with the volume ID (for example, FA123:1E3B).

Target Storage Complex

The nickname of the storage complex from which the target volumes for this relationship will be selected.

Target Binary GB

The size, in gigabytes, of the selected DS target volume for the specified relationship. The DS volumes are configured in binary format, where 1 GB (2³⁰) = 1 073 741 824 bytes.

Target Decimal GB

The size, in gigabytes, of the selected ESS target volume for the specified relationship. The ESS volumes are configured in decimal format, where 1 GB (10⁹) = 1 000 000 000 bytes

Size Inconsistency

This option indicates whether there are size inconsistencies with the volumes that you selected for the Metro Mirror relationships. The volume size that you select must be the same size and type for the operation to process successfully. The capacity of the target volume must be greater than or equal to the capacity of the source volume.

Note: If you proceed by selecting the Finish button and there are volumes in relationships with an inconsistent size, an error is generated that indicates that the relationship cannot be created because of the volume size inconsistency.

If the volume pairs are created successfully, you can view the main page to see status of the volume pairs.
