Jake are you updating one or more HMCs as well as the SEs? I would say if you are updating the Driver level on the SEs then you need to update the HMCs that talk to them. Updating an HMC can take a little time. As Dave said the update to the SEs can take some time. The dynamic process takes longer than if you turn over the box to IBM. I've had IBM do it both ways. In our case we can move workload around between two CECs so we could take one CEC down. I'm know when we gave the box over to IBM the process was done in well under 6 hours, which is our normal maintenance window. That time takes into account shutting down our lpars and restarting them plus the POR time.
So maybe the IBM person is taking into account the time to update one or more HMCs plus the SEs. Thanks..

I will tell you though that it was a lengthy process. Probably 8-10 hours if I remember right when we made that jump a year or so ago. We normally allot 5-6 hours of time for IBM to complete before our maintenance window, and in this particular case, we almost blew through our window of work because the updates ran so long. WE now schedule a 12 hour window for IBM to do their work just because of this. My team mate, might see this post and offer up a bit more information. _____________________________________________________________________________________________________ Dave Jousma AVP | Manager, Systems Engineering Fifth Third Bank | 1830 East Paris Ave, SE | MD RSCB2H | Grand Rapids, MI 49546 616.653.8429 | fax: 616.653.2717 -----Original Message----- From: IBM Mainframe Discussion List <IBM-MAIN@LISTSERV.UA.EDU> On Behalf Of Jake Anderson Sent: Wednesday, December 18, 2019 3:24 AM To: IBM-MAIN@LISTSERV.UA.EDU Subject: SE/HMC driver update duration **CAUTION EXTERNAL EMAIL** **DO NOT open attachments or click on links from unknown senders or unexpected emails** Hello We are updating our HMC/SE driver level. Our CE says the update takes 2 days to complete. I am trying to understand what are the factors which delays or takes time to complete the process.
