About this task

This task deletes a replica. The replica should be deleted from the source. However, it can be deleted locally from the target using a force flag is needed. 

Prerequisites

  • A replica

Before you begin

Deleting a replica from the source:

  • The replica definition is deleted
  • The link is not deleted
  • The source dataset is not deleted
  • The remote dataset is not deleted
  • Optionally - the staging area can be retained

Deleting a replica from the target:

  • The replica definition is deleted
  • The link is not deleted
  • The target dataset is not deleted
  • The remote dataset is not deleted
  • Optionally - the staging area can be retained

GUI Instructions

  1. On the InfiniBox GUI, right-click the Replication icon on the let toolbar to open the Replication screen.
  2. Right-click a replica and select Delete Replica from the pop-up menu.
    • An example of deletion from the source
       
    • An example of deletion from the target 
  3. Approve the warning message.
    The replica is deleted. 

InfiniShell instructions

Use the replica.delete command.

Retaining the staging area on the target

Deleting the replica with retain_staging_area creates a snapshot or a snap-group of the source and target entities. These snapshots are uniquely identified by the systems and can, later on, be used as a base for re-creating a replica on these entities.

However, this operation may fail in the following cases:

  • The replica is in Initialization phase, so the target is not consistent with the source
  • A dataset was added to the consistency group and the consistency group replica hasn't reached consistent state on the target yet

Best practice

It is advised to wait for the Initialization phase to complete prior to deleting the replica if you would like to retain the staging area.
