Increase Safeguarded Copy Backup Capacity per volume beyond the current limit of 14.6 TiB for CKD volumes

See this idea on ideas.ibm.com

When using maximum sized CKD EAV (Extended Address) volumes on the DS8K it would be useful to to have more than 14.6TiB of safeguarded volume capacity available.  If these large volumes experience high change rates they can easily use up all of the allowable safeguarded capacity for them.  This becomes a limiting factor on safeguarded copy retention when the desire is to have complete copy sets that includes all volumes within it.   With the limit in place it seems our only choice if we extend retention is to have partial SGCs with internal roll-offs for these large volumes.  Increasing the limit will relieve the constraint and allow customers to take advantage of complete SGCs for a longer retention period, as long as the overall SGC capacity on the DS8K is available.
