Correct. Each step will require a different IODF: 1. Config channels 1 and 2 offline. 2. Activate IODF+1 that redefines channels 1 and 2. 3. Config channels 1 and 2 online. 4. Be happy with what you see so far. 5. Config channels 3 and 4 offline. 6. Activate IODF+2 that is your desired endpoint. 7. Config channels 3 and 4 online. 8. Humbly accept accolades from coworkers and management :-)
Note: at step 4, you should have four paths to your old DASD as well as two paths to your new. You can stop there for a while if you like. -----Original Message----- From: IBM Mainframe Discussion List [mailto:[EMAIL PROTECTED] On Behalf Of Tom Sipusic Sent: Monday, January 08, 2007 10:49 AM To: IBM-MAIN@BAMA.UA.EDU Subject: Re: Dynamically Activate additional CUs on Shark It seems to me that Hal Merrit's stepwise approach will work. I think it will, however, require an intermediate IODF, in which the 2 new CUs are only defined to the two channels that will be offline when I do the first activation. (Also the two CUs I want to get rid of will only be deleted from the two off line channels.) Then I vary those two channels online and the other two channels offline and activate the configuration I really want, the one with the two new CUs that will handle the new DASD and the two CUs that have been handling all the old DASD volumes. and with the two new CUs defined to all four channels. (Gone too will be the two CUs that I am deleting.)
