Hi,
MSA 2050 LFF enclosure is supported as a expansion enclosure to MSA 2040.
HPE MSA 2050 LFF Disk Enclosure Q1J06A
NOTE:
• The MSA 2050 LFF and SFF Disk Enclosures are the recommended disk enclosures for capacity
expansion on the MSA 2040 storage systems.
• The use of MSA 2050 LFF and SFF Disk Enclosures with MSA 1040/2040/2042 storage requires
requires GL225 array controller firmware, or newer.
This 2U enclosure is designed to support twelve HPE Storage LFF
drives and accepts MSA dual-ported 12Gb SSD and SAS Midline hard drives.
I believe you have purchased the right set of SSD and SAS drives.
Also please confirm what is the firmware version on MSA 2040 controllers.
Also you must have Tiering license installed to create create DG of different disk types in pool.You can check by running #show license
