Changing domain name

Popular topic these days, eh?

Anyway I'm getting around to cleaning up the domain names on our 14 lpars
of IBM i. Seems we have quite a few varieties of domains. Some are set to
dekko.com, some corp.dekko.com and some dekko-1. Dekko-1 was our original
from some decades back.

Another issue was if you have a H/A (software) pair like TEST1 and TEST2
with their shared alias of TEST I found that the primary was TEST and not
TEST1. I'm going to clean that up too.

All LPARs should have all three domains in their domain search list.

I will ensure the Windows based DNS has the appropriate host and
alias/cname entries to support all three domains.

Generally we restrict the number of shares supported by IBM i, and
willingly accept any shares on the root as a letter of resignation. I'm
hoping this doesn't cause any issues with the few shares we have.

The manual doesn't mention any nastygrams about changing these at

Any of you been through this? Any thoughts to share?
