Create FlashCopy relationship — Verification

Introduction

After you specify FlashCopy relationships and select the copy options for the volume pairs, use the information that is displayed on this page to verify your selections. When you click the Finish button, a FlashCopy relationship is created between the source and target volumes, and the copy options are applied to the FlashCopy volumes that you selected.

Fields

Sequence number

Displays the sequence number that is defined for a FlashCopy relationship. The FlashCopy sequence number corresponds to a particular relationship that is being created. The sequence number is a maximum of eight hexadecimal digits in length.

Copy options

Displays the copy options that are enabled and disabled for the FlashCopy relationships that are created if the Finish button is clicked.

FlashCopy relationships created

The characteristics of the FlashCopy relationships that are created if the Finish button is clicked.

Source nickname

The nicknames of the FlashCopy source volumes.

Source Number

The volume number of the FlashCopy source volumes. The volume number is a 4-digit hexadecimal value that consists of the logical subsystem (LSS) number and the volume device number, LLVV, where LL is the LSS number and VV is the volume device number.

GB(2^30)

The size, in binary gigabytes, of the volume. One binary GB (2^30) = 1 073 741 824 bytes. Volumes of Type DS are configured in binary format. This method provides volumes that fully use the capacity in every extent.

GB(10^9)

The size, in decimal gigabytes, of the volume. One decimal GB (10^9) = 1 000 000 000 bytes. ESS 2105 volumes are configured in decimal format.

Target nickname

The nicknames of the FlashCopy target volumes.

Target number

The volume number of the FlashCopy target volumes. The volume number is a 4-digit hexadecimal value that consists of the logical subsystem (LSS) number and the volume device number, LLVV, where LL is the LSS number and VV is the volume device number.

GB(2^30)

The size, in binary gigabytes, of the volume. One binary GB (2^30) = 1 073 741 824 bytes. Volumes of Type DS are configured in binary format. This method provides volumes that fully use the capacity in every extent.

GB(10^9)

The size, in decimal gigabytes, of the volume. One decimal GB (10^9) = 1 000 000 000 bytes. ESS 2105 volumes are configured in decimal format.

Size inconsistency (Yes/No)

Indicates whether there is a size inconsistency with the volumes that you selected for the FlashCopy relationships. The capacity of the target volume must be greater than or equal to the capacity of the source volume. If the value of the Size inconsistency field is Yes, that FlashCopy relationship is not created.

Note: If you click the Finish button and there is a target volume in a FlashCopy relationship that is not the same type (fixed block [FB] or count key data [CKD] format) as the source volume, an error message indicates that the relationship cannot be created.
