I am blogging this mainly so I remember how to solve this
Big thanks to fellow ICS community member and all round great guy Robert Farstad for blogging this
Again you can see a problem when patching Docs 2 to CR2 as it can’t find the FQDN of the hosts.
The code has changed so it’s not possible to use the work around that we had previously.
There is a slight twist to getting it to work which Rob has explained fabulously so thank you mate .. you saved me a lot of grief .. and even IBM point people to that blog as they did when I opened a PMR to find out how to fix it .. 🙂
