About this task

This task deletes a replica. The replica can be deleted from either the source or the target. 

Prerequisites

  • A replica

Before you begin

Deleting a replica from the source:

  • The replica definition is deleted
  • The link is not deleted
  • Optionally - the source dataset is not deleted
  • The remote dataset is deleted

Deleting a replica from the target:

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

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 group of the target consistency group. It is assumed that the target replica is consistent with the source, so the snapshot group is capable of serving future replicas.

However, this operation may fail in the following cases:

  • The consistency group is in the Initialization phase, so the target consistency group is not consistent with the source consistency group
  • A dataset was added to the consistency group and a Sync Job has not started yet, so this dataset is not consistent

Is such a case, the retained staging area may require an Initialization the next time it is used for a replica.

Best practice

It is advised to wait for the Initialization phase to complete prior to deleting the replica.
