No, it doesn't. To IPL CP you have to IPL *something*. That *something* must be in the active I/O configuration. You need a tape drive and enough dasd volumes to restore a basic VM system, plus a console. This is the nice thing about having an emergency 1-pack micro-system. Sysres, paging, spooling, a directory, OPERATOR and MAINT, DDR, IOCP, all on one volume, with the console pointing to the integrated console (on modern machines, integrated 3270). Or, also on modern machines, the ability to IPL the z/VM DVD. IF you authorized the LPAR to perform dynamic I/O operations and you have dynamic I/O enabled in VM, then CP, once up, can start to add chpids, control units, and devices to the I/O config.
