Last week, I had posted the summary which follows below. Since then, I have
done IP reconfiguration
several times to refine the method.
The following steps seem to work just fine:
The general procedure is to do the following:
1. Make at least one good vdump of the contents of the ASE disk service(s).
On system A:
2. Make sure that the disk service(s) are located here
3. remove all cluster members except for this last one using asemgr
4. use asemgr to offline the disk service(s)
On Both systems:
5. asesetup -f f # to reinitialize the ase database
6. /sbin/init.d/asemember stop # to stop the ase agent
7. /sbin/init.d/aseam stop # top stop the availability manager
8. edit new addresses into /etc/hosts and /etc/rc.config
9. reboot both systems
One System A:
10. cd /etc/fdmns # if using Advfs
11. mkdir for each Advfs domain #if you are using Advfs
12. ln fs for each device, i.e. ln fs /dev/rz129c rz129c
13. showfsets ase_domain
14. mount t advfs ase_domain#ase /data
15. check that the data in /data is OK
16. asemgr on one system to reconfigure
Alternatively, and this may be better, after step 4, do steps 10 through 15,
then edit an entry into /etc/fstab for the ase disk services on system A.
Then mount them, say with mount a.
This way, when the system reboots after step 9, the data in the ase disk
services will be mounted and available.
With this approach, what is needed then is to then remove the ase disk service
entries from /etc/fstab before using asemgr to configure the cluster setup and
asedisk services, as asemgr won’t allow a service to be defined which is
already listed in /etc/fstab.

I had asked about the simplest way to change the primary IP addresses of
two members of an ASE TruCluster V1.5 system, and also for any information
about where the cluster configuration information is kept.

While some of the configuration information is kept in /etc/hosts,
/etc/routes, and /etc/rc.config, much of it kept in a binary file which can
be read by the asemgr -d -C command.
For what I need to do, the safest way seems to be to make the changes using
the asemgr menu, then check to make sure that /etc/hosts, and /etc/routes
and so forth have the right information.
