About this task

This task removes a member from a replicated consistency group on an InfiniBox system.

Prerequisites

• The link has to be up

Following the removal

• A new snapshot group is created, depicting the member removal (that is, no longer containing a snapshot of the removed member)
• When the last member is removed from a replicated consistency group, the consistency group retain the replication properties

Before you begin

The purpose of the consistency group is to group datasets in a way that will allow taking consistent snapshots for all of them. When a member is removed from a consistency group, it is no longer consistent with the other members of the group. If needed, the member can be moved to a pool other that the pool of the consistency group.

Instructions

1. Click on a replicated consistency group on the Consistency Groups tab.
   The Consistency Groups screen opens. 
2. Select a member (or several members) and click Remove Members. Three options are made available on screen: 
   
   1. Keep replicating the member individually - the member stays replicated and preserves its synchronization status
   2. Stop replicating the member - the member stops replicating and the staging area (the replication-associated snapshots) is deleted
   3. Stop replicating the member, but retain the staging area - the member stops replicating but the staging area (the replication-associated snapshots) is preserved
3. Click Remove. The member is removed from the consistency group.
