CPG change disk filter of active CPG with exported VV

[Sagi]

Hi all,

I would like to know if it's possible to change disk filter of active CPG with exported live virtual volumes?
Somehow I missed this step and CPG now take all FC disks and I want to take FC that the chunklets grater than 546GB, attached print screen with existing CPG,

Thanks in advance!

Yes, but change will only have any effect on new LDs created. Just changing it will not fix existing layout without running tunesys.

Is the "tunesys" has impact on performance or latency during this operation? any impact of SQL DB performance?

As with every question relating to performance, it depends. It will read and re-write all data that needs to be changed.

My experience is that tunesys will have a measurable but not severe impact. It's easy enough to cancel if it turns out to be unacceptable..
