Adding shared memory

Use the following workflow to add shared memory to a storage system in which TC pairs already exist:

1. Identify the status of the TC volumes in the storage system.
2. If a TC volume is in the COPY status, wait until the status changes to PAIR, or split the TC pair.

   Do not add shared memory when any volumes are in the COPY status.

3. When the status of all volumes has been confirmed, shared memory can be added to the storage system by your service representative. Contact customer support for adding shared memory.
4. After the addition of shared memory is complete, resynchronize the pairs that you split in step 2.
