Except for older CF stuff like TYPE=CFR, adding/deleting partitions and devices not defined with the dynamic feature I don't recall having to perform many PORs...
Paths to the control unit should be unique. See CUADD, etc. What do your CNTLUNIT and IODEVICE statements look like? What is the total disk capacity (ADDRESSes) you desire?

After adding additional disk capacity it will appear to be four control units on those four channels. I would like to dynamically activate the two new control units and associated I/O devices. When I tried to do this, it failed to activate. It seemed that the channels had to be offline, but the existing Shark DASD has to be online; so we took an outage and did a POR. Was the POR unavoidable? I ask because now I have to change the definitions of the new CUs, giving them different LCUs, and I fear that we'll have to do another POR unless one of you can show me how I can do a dynamic activation here.
