Adding and removing cache memory

Use the following workflow to add or remove cache memory in 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 or remove cache memory when any volumes are in the COPY status.

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