   Select a volume or a group to be joined to the master volume or the master group from the [Available Groups/Volumes].

   Volumes or groups conforming to all of the following conditions are selectable.

   Object	Volume	Group
   Conditions	Belongs to the class of the master volume Equal to the master volume in size Mirror type or single type (Volumes created in hierarchized mirror groups are also selectable. Any mirroring multiplicity is supported.)

Any mirroring multiplicity is supported.) Includes no volume Is not related to other master objects or proxy objects

   Status of Proxy Volumes That Can Be Joined
   "active" proxy volumes cannot be joined. To join an "active" proxy volume, stop the proxy volume in advance.

   When joining volumes, select a volume to be joined to the master volume and click <OK>.

   When joining groups, select a group to be joined to the master group and click <Next>.

   Clicking <Cancel> cancels the join process.

   
   

4. Defining attributes of proxy volumes created in the proxy group

   When joining groups, the Volume Attributes Definition dialog box appears.

   [Figure: Proxy Volume Attributes Definition]

   

   When a proxy group is joined to a master group, proxy volumes are created within the proxy group and joined to corresponding master volumes within the master group. In the Volume Attributes Definition dialog box, set attributes of such proxy volumes.

   1. Proxy Volume Name

      Assign volume names of proxy volumes. [Proxy Volume Name] shows default volume names. To change the default value, click and edit the volume name.

      For the volume naming conventions, see "Object Name."
      
      Automatically Generated Proxy Volume Names
      Proxy volume names are automatically generated as "master volume name" + "_" (underscore) + "proxy group name" (e.g. volume0001_group0002).

      
      

   2. JRM

      Set JRM (Just Resynchronization Mechanism) for volumes. The default value is "on." To turn "off", uncheck the [JRM] box.
      

      JRM for Volumes
      The JRM setting in the Proxy Volume Attributes Definition dialog box is the "JRM for Volumes" of the proxy volume. Note that it is not the "JRM for Proxies." For details, see "Just Resynchronization Mechanism (JRM)."

      When the settings are complete, click <OK>. Clicking <Cancel> cancels the join process.

      
      
      

5. Confirming

   A confirmation dialog box appears asking you whether to join the proxy.

   [Figure: Confirming "Join" (Groups)]

   A message window appears informing you that the join process is complete.
