It has always been the case that for a given system (e.g. z9), there is one and only one LPAR that should place the IOCP online; and only one LPAR that should be doing dynamic IOCP changes. This is somehow enforced by that "tokens" are used, and when z/OS is the master, a VM LPAR can no longer do dynamic changes. This is not related to z/VM having access to the IOCP source or not.
As fa as I know, HCP can even create IOCPs for other systems than the LPAR it runs on; in that case, it is useful to ship the IOCP source created by HCD to a VM on another system and use the IOCP command to place it online there. 2007/12/3, RPN01 <[EMAIL PROTECTED]>: > > Our I/O configuration is done completely via z/OS.
