Connection to CRS failed.Everything checked out on the Windows cell manager, and encrypted control was off on all nodes.
To start the Data Protector daemons on the Cell Manager host use the command
omnisv -start on the Cell Manager
or check if the communication between the Cell Manager and client is encrypted with the command
omnicc -encryption -status -all on the Cell Manager.
I ran strace on omnicc, omnicc -debug 1-200, tcpdump'ed every packet from the Linux system in question (there were none) and tried omnicc -server 220.127.116.11 (a non-existent address that should have been unroutable) which responded instantly.
Oh, and "omnicc -debug 1-200 2> /tmp/somewhere" doesn't put the same data into /tmp/somewhere as you get on stderr when you run "omnicc -debug 1-200" and stderr is a tty.
The root cause of the error message about being unable to connect to the server? The hostname of the Linux client didn't resolve correctly.
