Hi The only way to connect 10 zOS machines to a TS3500 library is to split the library into 10 logical libraries unless you have one zOS machine that can act as a library manager (through TSM for example). This is done through the admin interface of the 3500 and basically means you will have 1 drive for each zOS machine.
I'm no zOS specialist, so i'm not sure if DFSMS can handle library sharing. But only 1 machine can control a logical library, which means that you cannot have all zOS machine trying to act as library managers over a single control path. According to the DFSMS manual (http://publib.boulder.ibm.com/infocenter/zos/v1r9/index.jsp?topic=/com.ibm.zos.r9.idarc00/c8026.htm) it looks like you should be able to do this library sharing in DFSMS so that you can dynamically use the drives between all zOS machines, but like I said, I'm no zOS guy. Perhaps there is someone else on the list who knows this better.

How is the MPIO mechanism? P.S: 3592-C06 control unit has only four 4Gbps FICON ports for z/OS hosts path failover feature is available in the library. Thank you, Mehdi
