rSeries and tenant upgrades
I manage four r5900 appliances, hosting 16 tenants. The appliances are running F5OS-A 1.5.0; the tenants all run BIG-IP 15.1.10.2. We all know, of course, that the most recent QSN was released today. Normally, I'd upgrade everything to the latest version. However, where F5OS-A 1.7.0 is concerned, there is a "Known Issue" that raises a big red flag. In the release notes,
1380705-1 : BIG-IP tenant is stuck during boot up after doing tenant upgrade from 15.1.x to 17.1.x
The issue description says this will not happen with every tenant. But it just has to happen once to ruin a day, right?
In the past, I have always upgraded the appliance OS before upgrading the tenants. That just seemed to make sense. Given this issue, though, I am considering upgrading all of the tenants to BIG-IP 17.1.1.3 first, then upgrading the appliances to F5OS-A 1.7.0. Does anybody know of any pitfalls to this approach?
