DR Protection

DR Protection

This section explains how to quickly configure DR services after creating the protected group following the service configuration process.

Adding/Deleting a Protected Object

A protected object refers to an object (such as a database or LUN) for which eReplication provides disaster recovery (DR). eReplication allows you to add, delete, and modify authentication information about protected objects of a protected group.

Adding a Protected Object

This section describes how to add a protected object to a protected group.

Prerequisites

  • At least one protected group has been created.
  • The number of protected objects in the protected group has not reached the upper limit.
  • The template type of the protected object you want to add matches the existing type.
  • If the protected group have create a recovery plan, you can only add protected objects when recovery plan is in Ready, Clear completed, Rollback completed state or Reprotection completed.
  • A remote replication relationship must be set up between the storage LUNs where log files of each database instance reside or no remote replication relationship is set up.

Procedure

  1. On the menu bar, choose Protection and select the application type of the protected group to which you want to add a protected object.
  2. Select a protected group, and in the details area, click the Protected Object tab.
  3. Click Add.

    The Add Protected Object dialog box is displayed.

  4. Select one or more protected objects, and click OK.

    NOTE:
    • If protected objects are databases, you are required to enter the database user name and password for verification.
    • If protected objects are LUN, Local File System, Exchange Server, no verification is required.
    • When the asynchronous replication (NAS) DR technology is used, ensure that all the remote replication pairs are either not or in one remote replication vStore pair.

Deleting a Protected Object

If a protected object does not need to be protected, you can remove it from the protected group.

Prerequisites
  • At least one protected group has been created.
  • Multiple protected objects have been added to a protected group.
  • If the protected group have create a recovery plan, you can only delete protected objects when recovery plan is in Ready, Clear completed, Rollback completed state or Reprotection completed.
Context
  • This operation can be performed only when the protected group status is Normal.
  • When the protected group including database and NAS protected objects, all NAS protected objects can be removed, but you cannot remove the last database protected object in a protected group.
  • When the protected group status is Normal, you can add a removed protected object to this protected group again.

Procedure

  1. On the menu bar, choose Protection and select the application type of the protected object which you want to delete.
  2. Select a protected group, and in the details area, click the Protected Object tab.
  3. Select the protected object which you want to delete and click Delete in the operation area.
  4. In the Warning dialog box that is displayed, read the content of the dialog box carefully and select I have read and understood the consequences associated with performing this operation.
  5. Click OK.

Refreshing Resource Information

If storage devices, hosts or VMs change, but the changes are not synchronized to eReplication in a timely manner, you need to refresh this changed resource information before executing DR recovery. The resource information can be refreshed in either way: periodical polling using eReplication or manual refreshing.

Context
  • Periodical polling using eReplication
    eReplication periodically refreshes resource information. Table 6-16 lists the update periods of various types of resources.

  • Manual refreshing
    Table 6-17 describes the changed list of the storage devices, hosts or VMs and the related operation.

    Changed Item

    Storage device

    Host, host group, initiator, mapping view, file system, logical port, remote replication, consistency group in a remote replication, clone, HyperMetro, HyperVault or mirroring VIS change. For example, executing adding or deleting operation, the status changed.

    VM

    • Add or delete the VMs, or move the VMs to the other storage.
    • The LUNs used by datastore change.
    • The VMs change, for example, add or delete disks on the VMs, the network card change.
    NOTE:

    If the storage devices change, you need to refresh the storage devices.

    Host

    The initiator, application or storage information change.

Procedure
  1. On the menu bar, select Resources.
  2. In the navigation tree, select the site where the network elements (storage devices, hosts, or VMs) reside and click Refresh.

    In the upper right corner of the main page, click , in Background Task, you can view details about the refreshing.

    NOTE:

    In the cluster, if the host information has changed in the host group, you can refresh the host group to refresh all the hosts information. in the shortcut button area, select the host group reside and click Refresh in the operation area.

  3. On the menu bar, select Protection, and choose the protection objects type.
  4. Click the refreshed protected group, click Refresh on the Operation list to refresh information of the protected group.

    In the upper right corner of the main page, click , in Background Task, you can view details about the refreshing.

Modifying the Authentication Information

When the properties of a storage device are changed in the system, you must synchronize the changes to the eReplication to ensure that device properties in the DR management system are correct.

Modifying a Storage Device
  1. On the menu bar, select Resources.
  2. In the navigation tree, choose the site whose storage device you want to modify and click Storage.
  3. Select the storage device whose information you want to modify and click More > Modify on the Operation list.
  4. Change the name and authentication information about the storage device and click OK.

    Before you change the authentication information, enable Modify Authentication. Adding Storage Devices lists the parameters.

Modifying a Host

    Adding Hosts lists the parameters.

    • Before you change the authentication information, enable Modify Authentication.
    • Before you change the alarm reporting parameters, enable Modify Alarm. The SNMP type and environment engine ID cannot be modified.

Modifying a VRG
