Hi Sahana R.
Thank you for all the information and assistance.
I am trying to create a Virtual disk group with the SSD's. I have as a test created a Linear Disk group and that works. But with Linear disk group it looses alot of functionalty so need to create virtual disk group. So it looks like it could be tiering license issue.
Other thing I notices is when I create a Virtual disk group from the SAS disks in the expansion enclosure, it does not create disk type as "SAS(standard). It creates it as "SAS MDL(archive). Is this also related to tier license?
