Merge Two Groups

  • Check array cabling. For more information about cabling, refer to the Storage Quick Start Guide for your arrays.

  • Ensure that the network configuration is correct.

  1. Log into the group leader array for the group into which you will merge a second group.
    The group that you log into is the destination group. It has the group leader array and up to two other arrays, one of which might be the backup group leader. This group will merge with a second group, which is the source group and has only a single array.
    NOTE: The merge operation takes the following actions with regard to backup group leaders and the destination group and source group.
    • If the destination group includes a secondary management IP address, the merge operation ignores any secondary management IP on the source group.
    • If the destination group does not have a secondary management IP address, but the source group has one, the merge operation gives you the option to use the source group secondary management IP address.
  2. Go to Hardware.
  3. Click Actions → Add Array to Group.
  4. In the Add Array to Group dialog box, locate the array that you want to add to the group and check it.

    The group to add (source) must contain an array that runs the same array OS version and the same iSCSI or Fibre Channel data protocol as the group leader array (destination).

    A list of arrays is displayed. The GUI displays error icons for incompatible arrays in the groups. Hovering over an error icon displays a list of error that must be resolved before you can add the array to the group.

  5. Type the Administrator password in the Password field, then click Connect.
  6. Click Add.

    A dialog is displayed to validate what is needed to successfully complete merging the two groups. The dialog also identifies the consequences of the merge. Be sure to read this information carefully and take all recommended actions. Some of the notifications include:

    • Any merge conflicts, such as common initiators with user-assigned alias conflicts.
    • Logical Unit (LU) number conflicts — For the same initiators accessing volumes on both the source and destination groups, it is possible that the same LU number could be assigned to volumes on both the source and destination groups. Because different volumes cannot be exposed to the same initiator using the same LU number, the merge validation will fail. The validation report will show the conflicting LU numbers, and these must be changed manually before the merge can be successful.
  7. In the Validation successful dialog box, click Finish.

    A progress bar identifies the progress of the merge process. If the process completes successfully, a subsequent message provides status about the successful completion of the group merge.

  8. Click Close.

    Both arrays appear in the Arrays panel as members of the destination group. Make sure that you now use the management IP address of the Group Leader array.

  9. Select Manage → Array to verify that the two groups have been merged.
  10. If applicable, register the HPE vCenter Plugin again.
    NOTE: If you unregistered the HPE vCenter Plugin before completing the merge of the two groups, you must register the HPE vCenter Plugin again.

    To learn more about registering the HPE vCenter Plugin, see the VMware Integration Guide.
