Because we have 3 HMCs that are configured to control all 3 of our CECs, IBM suggested we upgrade the HMCs ahead of the CECs. I don’t' recall the exact problem, but I do know that after upgrading the first CEC, we could no longer control that one using an HMC that wasn't at driver 36 yet (first CEC upgrade was completed before last HMC). So the HMCs were done ahead of time, during the day, non-disruptive to anything but the HMC itself. We had no problem accessing pre-Drive 36 HMCs with HMCs that had been upgraded to Driver 36 (backward compatible). Seems the HMC upgrades were started early in the morning, and completed by noon. I don't recall the specific times for these upgrades. But this is activity that can be done prior to the CEC Driver 36 upgrade. Our first CEC upgrade to Driver 36 took over 18 hours elapsed. The CE completed the upgrade to Driver 36 and was trying to get to a higher bundle level and spent a lot of time on the phone with the support center, as well as a break for another service call. Long day... The 2nd and 3rd CEC upgrades to driver 36 were about 9 and 7 hours. We did not have the problem getting to the next bundle level with these. Not sure if the time since last MCLs were applied makes a difference, but we had applied MCLs about 6 months before we went to Driver 36, so we were fairly current. If you are way behind, maybe this could be a reason for the longer estimated time. Getting to Driver 36 was a non-disruptive process, IBM performed this work while all systems were up and running. I guess if your CE wants 2 days, just start 2 days before you plan the disruptive POR.

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.
