Associating a data volume to an RDS

Use the Associate Volume task to associate a volume to an Replicated Data Set (RDS) even when replication is in progress. This command associates a volume to all the RVGs of the RDS.

Ensure that volumes of the same name and same length exist on the Primary and all the Secondaries of the RDS. You must create volumes of the required layout on the Primary and the Secondary.

  Caution   Failure to meet the following prerequisites may result in the Secondary data volumes having unusable data.

Prerequisites for associating a volume to an RDS

  Ensure that volumes of the same name and length as the Primary volumes exist on all the hosts in the RDS. If not, create them.

  Verify that the volume to be added is inactive.

  Synchronize the volume using the vradmin syncvol command from the command-line interface (CLI).

  Note   By default, the Associate Volume task associates Data Change Maps (DCMs) to the volumes being added to the RDS, if DCMs have not been associated already. If any of the data volumes contains a DRL, this operation removes the DRL before associating the DCM to the volume.

 To associate a volume with an RDS

1. Select the name of the RDS to which you want to associate the volume. For example, hr_rvg.
2. Choose Replication > Associate Volume. To use the pop-up menu, right-click the name of the RDS in the tree-view and select Associate Volume.
3. In the Associate Volume dialog box, select the name of the data volume to be associated with the RDS. If the RVG contains VxVM ISP volumes, the list displays VxVM ISP volumes only.
4. Click OK. The result box displays a message, which indicates whether or not the operation succeeded.
5. In the result box, click OK.
