Changing the Leading Interface on Multi-Domain Server or Multi-Domain Log Server

This procedure lets you change the current Leading Interface on a Multi-Domain Server or Multi-Domain Log Server.

1. Connect to the command line on the Multi-Domain Server.
2. Log in to the Expert mode.
3. Stop the Multi-Domain Server:

   # mdsstop

4. Modify the $MDSDIR/conf/LeadingIP file:
   1. Back up the file:

      # cp -v $MDSDIR/conf/LeadingIP{,_BKP}

   2. Edit the file:

      # vi $MDSDIR/conf/LeadingIP

   3. Change the current IP address to the new IP address.
   4. Save the changes and exit the Vi editor.
5. Modify the $MDSDIR/conf/mdsdb/mdss.C file:
   1. Back up the file:

      # cp -v $MDSDIR/conf/mdsdb/mdss.C{,_BKP}

   2. Edit the file:

      # vi $MDSDIR/conf/mdsdb/mdss.C

   3. Find the Multi-Domain Server object that has the source Multi-Domain Server's IP address.
   4. Change the object's IP address to the new IP address.
   5. Do not change the Multi-Domain Server's name.
   6. Save the changes and exit the Vi editor.
6. Install a new license on the target Multi-Domain Server issued for the new Multi-Domain Server IP address.
7. For multiple Multi-Domain Server environments, repeat Steps 1 to 5 for each Multi-Domain Server that has a changed IP address.

If your target machine and the source machine have different interface names (for example, eth0 and eth1), follow the steps listed below to adjust the restored Multi-Domain Server to the new interface name.

To change the interface:

1. Change the interface name in file $MDSDIR/conf/external.if to the new interface name.
2. For each Domain Management Server, replace the interface name in the $FWDIR/conf/vip_index.conf file.
