Manually changing configuration of a replication group - assure_mimix - 6.0

To change a replication group, do the following:

1. Navigate to the Replication Group portlet.

2. Click Configuration.

   The Configuration Window displays. For detailed information refer to the Assure MIMIX for AIX online help.

   

3. Click Change Replication from the Actions dropdown. The following messages may appear:

   1. The Change Replication Group dialog displays with a warning:

      “Replication group cannot be changed because it is either failed over or the partition has been migrated using Live Partition Mobility.”

   2. The Change Replication Group Servers panel displays with a warning.

      “Replication group is currently active. Configuration changes cannot be saved until the replication group is stopped.”

      Configuration changes cannot be saved until the replication group is stopped. However, when you click Finish on the Summary panel, a message will appear that instructs you to stop the replication group. To stop the replication group, navigate to the Replication Groups portlet in the Assure UI portal window and stop the replication group.

   If these issues do not occur, the following panel displays.

   
4. Click Next.

   The Change Replication Group Servers Login panel displays if you are not logged in. Use this panel to log into the server specified in the panel.

   
5. Specify the username and password and click Log In. Log in to each server to retrieve information. When you run commands, context IDs are used to identify the replication group. The context IDs specified have been defaulted to unique IDs on the servers in this replication group.
6. The Change Replication Group Servers panel displays again showing the login status of each server.

   

7. Click Next.

   The Change Replication Group Names panel displays.

   
8. Click Next.

   The Change Replication Group Default Volume Groups panel displays.

9. Click Next.

   The Change Replication Group Logical Volumes panel displays.

   1. Click Add to add a logical volume using the Add Logical Volumes dialog, shown below. For detailed information, refer to the Assure MIMIX for AIX online help.

      

   2. Select one or more logical volumes to protect on the production server.

   3. Select the volume group on the recovery servers where the replicated data will be located.

      Note: The Add Logical Volumes dialog will not contain any logical volumes that are in use by other replication groups on the node.AIX standard logical volume types (such as, raw, jfs, jfs2, jfslog, and jfs21og) are allowed. AIX system internal logical volume types (such as, aio_cache, boot, copy, paging, sysdump) are not allowed. Any other non-standard logical volume types are allowed as “raw” logical volumes. If a jfs or jfs2 logical volume is presented without an associated filesystem path, it will not be available for protection.

      Click OK.

      The Change Replication Group Logical Volumes panel displays with the selected logical volumes you want protected.

      

      • Select the logical volume(s) you wish to change for this replication group and click Change.

      Use the Change Logical Volumes dialog, shown below, to choose a different volume group for the replica logical volumes, on the recovery servers. By default, the default volume group specified is used for this purpose. For detailed information refer to the Assure MIMIX for AIX online help.

      

      • Select the logical volume(s) you wish to change or remove for this replication group and click Remove.

      Use the Remove Logical Volumes dialog, shown below, to remove the selected logical volumes from the replication group. These logical volumes will no longer be protected. For detailed information refer to the Assure MIMIX for AIX online help.

      
10. Click OK on either the Change or Remove Logical Volumes dialogs.

    The Change Replication Group Logical Volumes panel displays.

11. Click Next.

    The Change Replication Group Replication IP Addresses panel displays. By default, replication uses the IP addresses of the servers. You can specify IP labels or addresses that will be used specifically for replication. There are two options:

    • If you select, Use server IP addresses for replication, the following panel appears.

    

    • If you select, Use specified IP addresses for replication, the following panel appears.

    
12. Click Next.

    The Change Replication Group Containers panel displays. Containers are used by internal processes and replication to move changed data between servers.

    
    Note: If you make configuration changes on the Container panel you could lose CDP. For example, if you change the Size of each container field, you will lose CDP. This will be reflected in the Change Replication Group Summary panel displays, as shown page 150.
13. Click Next.

    The Change Replication Group Container Options panel displays. Use this panel to specify if you want to:

    • Use compression during replication.

    • Use encryption during replication. See Support for data encryption in Assure MIMIX DR for AIX.

    • Send partially filled containers after a specified amount of time. Otherwise, containers are sent when they become full.

    
14. Click Next.

    The Change Replication Group Snapshot Buffer panel displays. When a snapshot is created, the snapshot buffer is used to hold the changes between the location in the rollback window where the snapshot was created and the current time. As changes are replicated, the snapshot buffer fills up.

    
15. Click Next.

    The Change Replication Group Ports panel displays. Port numbers are used for communication by the agents on each server. If you enter a port number value that is already in use, the service name that is using the port will be displayed in an error message.

    
16. Click Next.

    The Change Replication Group Tivoli Storage Manager panel displays. Tivoli Storage Manager (TSM) can archive containers which allows you to rollback or take snapshots farther back in time. Full backups of the server where the TSM client is running can also be performed.

    
17. Click Next.

    The Change Replication Group Summary panel displays and shows a summary of this replication group's configuration. If you have made configuration changes on the Containers panel (see #XREF_47011_Manually_changing__XREF_18264_If_you_makepage 147), proceed to Configuration changes will reset the rollback window (CDP is lost).

    Note: When you decide to make configuration changes to the replication group, they can only be saved if the replication group is stopped. Use the Replication Group portlet on the Replication page to stop the replication group.
    
18. To save and initialize this configuration on the specified servers, click Finish.To view a summary of the changes you made, refer to Configuration window for Replication Groups. The content of this panel is the same as the Configuration Summary section in the Configuration Window. Refer to the Assure MIMIX for AIX online help for additional information for the Configuration Window. Refer to Configuration window for Replication Groups.
