We have a customer installation where we try to install a HANFS
cluster.
The nodes are Model 370s. The shared disks are in one 9334-501.
The hardware is correctly installed, the disk takeover works fine
when it is done manually.
However, if they try to start HANFS, the message
hanfsd: Cannot get valid configuration information (227)
appears, and hanfsd terminates.
I have appended configuration information, configuration files and
the contents of the log file.
What is wrong here? Thanks in advance.

ANSWER
Thank you for your very complete description of your configuration. The
error code number 227 that you are getting in your hanfsd error message
means that the configuration of your tertiary interface is missing or
invalid. You might want to redo the configuration of your tertiary
interfaces on both machines, and also check to see that you have IP
labels (hostnames) and IP addresses for those interfaces defined in
your /etc/hosts file on each machine. Since you have given such complete
information, I have also found some other things that will cause
problems for you, so I have the following suggested actions to make sure
you can get HANFS successfully running.
1. In your section where you list the contents of your /etc/hanfs
configuration file on each machine, there is a problem in your first
3 entries (ptwin, stwin, ttwin) on each machine. These are supposed
to be filled in with the addresses of the other machine in the pair,
not for the machine itself. For instance, your corrected entries
should be:
RS6DBS RS6ONT
ptwin = 193.58.99.154 ptwin = 193.58.99.152
stwin = 193.58.99.155 stwin = 193.58.99.153
ttwin = 192.1.1.2 ttwin = 192.1.1.1
NOTE: If you were using the example in the redbook "High Availability
Strategies for AIX" as a guide, I must apologize. The example
in that book has made the same mistake. This will be corrected
in an update to the book.
2. It is not shown in your information, but one step that is easily
missed is as follows. On each machine, the primary network interface
(in your case tr0) must be in a detached state when HANFS is started.
This can be done through the "smit chinet" panel.
3. In your "Configuration Information" listing that you have provided,
you say that "tok1" is the Primary Adapter on RS6ONT. I think this
is probably just a typing mistake, but it should of course be "tok0".
Also, in this section, I would suggest that you assign unique IP
names to your secondary interfaces (for instance RS6DBS_sec and
RS6ONT_sec). These unique names should also be reflected in the
/etc/hosts files on both machines.
I hope these suggestions help to get your HANFS configuration running
successfully.
