Creating CLPRs
If you have not yet created a CLPR, the entire cache appears in CLPR0 in the Partition Definition pane. To
partition the cache, create a CLPR. The created CLPR can be allocated to each SLPR, and CLPRs can be
created in a selected SLPR. Only the Administrators can create CLPRs.
NOTE:
When you create a CLPR, the default cache size is 4 GB. To create a CLPR, the desired cache size

Residency Size and Partial Cache Residence Size from the Cache Size of CLPR0, must be 8 GB or more.
