If you are at the right software levels then you could even use the zFCP support to talk directly to the SAN to non-ECKD type disks.
-----Original Message----- Hello Tim, We have a HDS 9960 for both mainframe and Open systems usage. To use Linux/390 your 9900 will need to be configured with ESCON or FICON adapters and some of your existing disks formatted for mainframe use, or if you have none that can be freed up, acquire additional disk and have it formatted for the mainframe (3390 ECKD format).
