Tom - Think of the DLM as the head of string Tape controller (from the old days) that provides the UCB's. Then there is some form of Storage attached (think the physical tape that got mounted) - in our case this is a DD4500 as an example. EMC allows only certain Storage to attach to the DLM.

There is no storage on it. The needs to be another piece of equipment to provide the storage for the actual tape usage. I think you are asking can you use a storage device other than EMC equipment to hold the actual tape data. Is that correct? If so, I have not seen any documentation that would indicate anything other than EMC equipment can be used for the DLm for their actual tape data. This link does not show anything other than EMC equipment. Currently, VMAX, VNX, DD are the only devices I have seen that works with the DLm. https://www.emc.com/collateral/hardware/data-sheet/h4207-disk-library-mainframe- ds.pdf So, you are probably trying to see if anyone used something other than EMC equipment with the DLm and was successful.
