Hello Vijay Ayar,

Do you have both your Adapt & R10 in the same pool or are they in different pools?  Are you using Virtual storage or Linier storage? Can I get a support log from your ME4024 so that we can look into how you have configured your system?

Please let us know if you have any other questions.

[Vijay Ayar]

 We have setup Adapt on Pool A with Virtual storage And  we have setup Raid 10 on Pool B with virtual storage.
