Deleting a HyperMetro Pair

Deleting a HyperMetro Pair

If a HyperMetro is no longer needed, you can delete it.

Prerequisites

You can delete the HyperMetro pair only when its Pair Running Status is Paused, Force Start, Invalid, or To be synchronized, and its secondary LUNs are not mapped.

NOTE:

If the Pair Running Status is Invalid, you can only delete the local storage system's configuration information. To delete the remote storage system's configurations, you must perform this operation on the remote storage system separately.

Procedure

  1. Log in to DeviceManager.
  2. Choose Data Protection > HyperMetro > HyperMetro Pair.
  3. Select a HyperMetro that you want to delete and click Delete.

    The security alert dialog box is displayed.

  4. Optional: If the Pair Running Status is Invalid or the local and remote storage systems are disconnected, select Only delete the configuration information about the local device if the HyperMetro vStore pair fails or the remote device is disconnected.

    NOTE:

    You must select this item to delete the HyperMetro pair.

  5. Optional: Select Stop the LUN service of this device based on site requirements.

    NOTE:

    This operation must be performed on the local site or remote site (it is advised to set "Local Resource Host Access Status" as an "Access denied" storage device). After this operation, the WWN of the LUN on the storage device will change. Rescan the LUN on the host. If the LUN service is not stopped on both HyperMetro sites, there is risk of data inconsistency.

  6. Select I have read and understand the consequences associated with performing this operation and click OK.
  7. The Execution Result dialog box is displayed indicating that the operation succeeded.

    NOTE:

    After deleting a HyperMetro pair, scan for storage resources on the host to ensure that the host can correctly identify the storage resources mapped to it.
