Suspend — Select volumes

Use this page to select either a source or target volume on which to suspend. During the suspension, the storage unit does not copy data to the target volume of the volume pair.

Introduction

When a volume pair is suspended, Metro Mirror stops transferring data to the target volume, which results in the target volume becoming out of synchronization. During this time, the storage unit keeps a bitmap of the changed tracks on source target. Later, you can resynchronize the volume pair to allow only the changed tracks to be copied to the target volume.

Real-time manager > Copy services > Metro Mirror > Select a volume pair > Select Action: Suspend... > Go

Fields

Select which volumes to suspend, based on the following criteria:

Suspend at source: The suspension is issued to the source volume in a Metro Mirror relationship. As a result, the target volume will become suspended immediately afterwards
Suspend at target: The suspension is issued to the target volume in a Metro Mirror relationship. As a result, the target volume becomes suspended, but the source might not. You should use this option only in a disaster situation when the source LSS is not available anymore.
