The short answer is this is going to get ugly. You will need to convert an LSS from S390 usage to OPEN access. This is a totally destructive process, so you will need to get the S390 data off the LSS before starting the conversion.
You will need to define the host systems to the ESS that will access that LSS. This is roughly the same process that you went through for the S390 side. Cache will be shared between all accessors of the box. This could lead to problems if the non-S390 systems become very active, which could lock out the mainframe, causing further problems.
