>From mvs (master console) you'd cf(config) the chipid online(on),then vary the path and the devices online. What I don't know is what you'd do to have it offline to VM so those devices wouldn't rec an interrupt from VM.
Mace -----Original Message----- From: The IBM z/VM Operating System [mailto:[EMAIL PROTECTED] On Behalf Of Shimon Lebowitz Sent: Wednesday, December 20, 2006 5:02 AM To: IBMVM@LISTSERV.UARK.EDU Subject: IOCP dynamic reconfiguration This looks like an MVS question, but it's really not - I do all the IOCP preparation from VM, for both the VM and the MVS boxes, and have to explain to the MVS people why it's not necessary to do it in MVS for that box. In my IOCP I have CVC channels (ESCON Converter to parallel [bus/tag] devices) defined with PART=(MVSPROD,REC) so that they will be reconfigurable. In the IOCP listing, these channels show up with MVSPROD as the Accesslist, and all other LPARs as 'C' - the Candidate list. In order to move the channel from MVSPROD to a different LPAR, we used the 'Reconfigure' item in the HMC, but our MVS consultant says we should have been able to just vary the path online in the other MVS. He suggested that I change the PART= to read like this: PART=((MVSPROD),(MVSTEST,SYSTST),REC) I tried compiling an IOCP like that, and it looked to me like all I achieved was to *decrease* my candidate list from *all* LPARs, to only the named ones. Does anyone here have experience with moving reconfigurable paths from within an O/S, without going to the HMC? What needs to be done to enable that function? It occurs to me that perhaps I just need to change the IODF of the other MVS to know about this channel, even though it finds it offline. Would that do the trick? If so, what would be the solution for VM LPARs? (Hmm.. put the offline channels in DMKRIO?? <g>) Thanks, Shimon -- ********************************************************************** ** Shimon Lebowitz mailto:[EMAIL PROTECTED] VM System Programmer .
