Was wondering if possible can you change the Set Size on a CPG on the fly and if so, how much space is required to make a change like that? Thank you, Phil |

Are you saying change from, 6+2 to 14+2? If so I believe it can be done on the fly but it will only affect the allocation of new chunklets, not existing ones. If you want to change existing chunklets you'll need a new CPG, DO, and enough space to copy at least one vvol. |

That kinda depends on the code level. At 3.1.2, you can change the CPGs set size and it will re-tune existing volumes as well. So no need to create a new one and 'move' stuff about. TD |
