Increment of space are for data collection

Ds8K are used in big and complex environment, and Copy Services solution are increasing in size and mode (Multi-site, different Copy Set, Topology, etc)

In case of Test performed by Client or also during the workday operation , if an error in encountered, a specific data collection is required

Recently I've seen different scenario where Data collection performed has been collected too late compared to the event and due to a combination of Big solution, plus time elapsed, the data collection is useless because doesn't contain necessary data (over-written)

Request is to have space increased to be able to contain a larger time window or possibly have this area enlarged on Customer based request (example when performing a functional test like site swap or DR Test)

An event detected during test if well analyzed and corrected cold improve solution and reduce Impact in case of real scenario


Thanks

    I'm not able to provide additional technical comment

    Idea arose because several Copy Services case are returning with reason of lack of data or data insufficient, because over-write caused by reduced "log area"
    So the request is to have the log area enlarged 
    See as reference case CSP TS022170532 where Customer had to recreate the event because data collection (ODD Dump) collected at time of problem where gone due to lack of space in area log
