Thank you all for your replies.... I guess I've got it ;)
Well.... when I stared adding my own volumes my intention was to use device addresses that are "far away" from the addresses of the IBM supplied volume (so my volumes will probably never conflict/use addresses that will be used by IBM supplied volumes). So I've thrown an eye into the HCD and found a device address range for 16 devices, starting at address AF0. Well... the Online/Offline switch was completely new to me so I've not payed attention to this parameter. And yes, I took the wrong address range :-( AF0,16 is configured to be completely offline at startup..... I use addresses starting at AD0 now and everything is working like a charm.... Thank you guys!

It may be something in here which is inhibiting initial online status, although I defer to the IODF comments made by more knowledge folk than I in that area. As others have said if you wish to automate the change to online then including a VARY command in COMMNDnn would be prefereable to IEACMDnn which conventionally is reserved for IBM issued commands.
