I upgraded all of my production IOCs from autosave R4-8 to R5-1 in September 2013 and I did not have any problems.  This includes 8 vxWorks IOCs, ~20 Linux IOCs, and ~10 Windows IOCs.

Subject: Autosave upgrade issue

 


I upgraded my autosave libraries on a system being commissioned. To my surprise it stopped working.
Worse, it worked partially. we quickly realized that our new BPM calibration was wrong (non default values were restored though, obviously from an older save file). We restarted the IOC then some other values where incorrect. Autosave even turned on my kicker magnet. ( i.e. this autosave upgrade could really have been a safety hazard!)
I quickly identified autosave as the most likely culprit. Indeed autosave had been upgraded just a couple of days before.
Although I could go back to what I had before, I tried to move forward. What I found is that I had upgraded from autosave 4-5 to 5-1. Then I realized that the config files which had been generated by 4-5 were being used by 5-1.
Could this be the issue?

After rebooting a few times and correcting the incorrect values, it seems that now 5-1 is working correctly.
But is it?
How to make sure that it is the case?
Should  I wipe out all of my autosave configuration and start from scratch?
Is 5-1 ready for production?

Regards,
