How to Aruba Clearpass (CPPM) disk is extended in m5.xlarge instance on AWS?

Hi All,

I am working on HPE-Aruba. Partner did installed Clearpass v6.11 (CPPM) of AIM on AWS. Recommanded instance of CPPM is m5.xlarge type that 4 CPU, 16GB RAM, 1000GB disk space. (https://www.arubanetworks.com/techdocs/ClearPass/6.11/Installation-Guide/Default.htm#SystemRequirements/SR-AWSRequirements.htm) If it has installed it, CPPM have not engough the disk size of requirement. (should minium 160GB but still 38.80GB leak status). so we increased more disk size on EBS volume 2 (sdf) but it still same size of 38.80GB.

(Request) How to release the disk size on m5.xlarge instance on AWS?

If you know that case, please share to me about this issue ASAP. Thanks.
