We have had maintenance (MCL) applied to our HMC and OSA cards, we now need to activate this maintenance. The standard way to activate the applied maintenance is to "power on reset", at this point we are unable to take an outage for this. We have a short maintenance window, too short to power down our Linux, z/VM Lpars and z/OS Lpars.
We have seen some posts on ways to individually offline and online (start and stop) the OSA's to pull in the new maintenance. Our question for anyone that has gone through something like this, is there a sequence or procedure for this scenario? If so is there a documented "step and order process" and most of all what "gotchas" should we be aware of? System: z/196 HMC 2.1.1 1. z/OS 1.12 (DB2, IMS, CICS, MQ) multiple Lpars 2. z/VM 5.4 hosting Linux 10, 11 3. OSA's (OSD, OSM, OSX and IQD) across all platforms. Any thoughts would be greatly appreciated. Do not go gentle into the good night, rage, rage against the dying of the light.
