Verifying the Configuration

Verifying the Configuration

After a volume mirror is created, you can remove the mirror copy to judge whether the volume mirror can ensure continuous host services when the mirror copy is faulty.

Prerequisites

  • The connection between the storage system and the application server is normal.
  • At least one volume mirror has been created in the storage system, and the Health Status is Normal and the Running Status is Normal.

Context

Only system administrators are allowed to verify the configuration.

Procedure

  1. Map the mirror LUN to the application server.

    1. Log in to DeviceManager. Choose Provisioning > LUN > LUN Group. Click Create to create a LUN group and add the mirror LUN to the LUN group.
    2. Choose Provisioning > Mapping View. Choose the mapping view that the host group which holds the application server belongs to. Then add the newly created LUN group to this mapping view.

  2. Log in to the application server and write X.txt to the mirror LUN.
  3. Log in to DeviceManager. Choose Data Protection > HyperMirror.
  4. Select the mirror LUN and then the mirror copy that you want to delete and click Delete to delete the mirror copy.

    After the mirror copy is deleted, the Health Status of the mirror LUN is Degraded.

  5. Check whether host services are interrupted.

    • If yes, the volume mirror configuration is incorrect. Check DeviceManager to find out whether there is any volume mirror–related alarm. If yes, clear the alarm, create a volume mirror again, and repeat the preceding verification steps. If no, contact technical support engineers.
    • If no, the volume mirror is correctly configured and can be used normally.
