I believe when you don't specify a candidate list it assumes the contents of the access list. Since a CVC channel can only have one partition in its access list the candidate list needs to be populated accordingly in a reconfigurable channel scenario.
As for keeping it offline to VM, if the device is not used by VM and if appropriate, just exclude the applicable channel from the access/candidate list of the channel in question.

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 .
