You only need to vary off/on when the "to" device volser changes. This is to let CP know to update the incore copy of the volser info.
This is not required if the "to" volume wasn't changed, nor is it required if you flash minidisks. But if you flash minidisks the guests that are using those minidisks need to be made aware that they need to process that vcua as if it is a new pack. (reaccess in CMS), Perhaps IPL VSE or online the mindisk. etc. Tom Duerbusch THD Consulting >>> Mark Pace <mpac...@gmail.com> 2/24/2010 1:27 PM >>> I found that the devices you want to flash need to be varied off and on once in order for the flash code to work.
