NIS Migration

[Manoj Sivan]

Hi,

We are having two NIS servers( each having slaves seperately) under HP-Ux 11.11. We would like to consolidate as one server (and slave)

Can anyone guide me in migration, by steps (both master and slave side).

Thanks in advance

Manoj

Hi Arun,

Those doc links are not active now. I will explain my setup.

I do have

NIS Master-A NIS Master-B
NIS Slave-A NIS Slave-B

I want to remove NIS Servers-B from network as a part of server reduction. So i need to migrate all databases from B to A. SO i am requesting the procedure for that. Also what are the necessary changes i need to impliment at clinet side ?

Thanks and regards

Manoj

Manoj,

I assume that these are two different NIS domains and are also on the same subnet. What you will need to do depends on how you have your NIS-B domain set up, with respect to your NIS-A domain.

At a minimum, you will need to make sure all the host, passwd, group and netgroup files on NIS-B are included in NIS-A. If you are also using auto.master, auto.direct, auto.indirect or auto.home maps on NIS-B, these will also have to be included in the appropriate NIS-A files.

Once that is done, you will have to run /var/yp/ypmake to create the new NIS maps. Then you would probably want to reboot the NIS-A master, or stop and start the ypserv daemon with /sbin/init.d/nis.server stop|start.

On the client side, you will need to update the /etc/rc.config.d/namesvrs file to the new NIS-A domain name. Then you can either reboot the clients, or execute /sbin/init.d/nis.client stop
/sbin/init.d/nis.client start

If you have any security set up in your /etc/exports file on any NFS servers that are specific to NIS-B, this will have to be updated on the NIS-A server as well. Then you would re-export all exported NFS filesystem on all NFS servers.

If all that goes well, your clients should connect to the NIS-A domain.

A valuable resource is the HP website: Administering NFS services. This is available at:
