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.
