This morning, I upgraded OnTAP from 8.2.4P6 to 8.2.5P1 on our 3270 HA Pair which only serves as a SnapMirror destination system for the few systems we have still running 7-mode.
Inexplicably, all SnapMirror jobs are now failing. The system indicates it cannot connect to the source filers. From what I could tell, the change might have happened after a subsequent, automatic upgrade of the service processor to version 1.4.4. I noticed I could no longer connect in System Manager via the replication IPs like we had for years, and I had to switch to using the managment IP's. I'm showing no errors when running ifconfig -a.
We have made numerous upgrades on this system for the past seven years, and never have we had snapmirror suddenly stop working like this. Any recommendations or suggestions?
