IBM FlashSystem storage only supports IBM configured drives - these drives have IBM special configuration and firmware levels and must be purchased from IBM, a certified IBM reseller or GARS.
We don't sell drives by Vendor, we sell them based on qualified parts for a capacity and technology type, but you should be able to purchase the MES drive (which is the drive and carrier) for the tech type and capacity you are looking for.
If you purchased this Samsung drive in the open market it will not be supported in your FlashSystem. I hope this helps.
update:
@Ibraheem Zia - No we don't support third party drives that have not been configured for IBM in Manufacturing (so if you buy a drive direct from Samsung and plug it in, the FlashSystem will reject the drive and refuse to use it).
This is in the documented for our other products, but appears to be missing from the documentation for the 5015, I'll see if we can get that corrected.
