To configure LLT and GAB on the new node

1. Edit the /etc/llthosts file on the existing nodes. Using vi or another text editor, add the line for the new node to the file. The file resembles:

   0 galaxy
   1 nebula
   2 saturn

2. Copy the /etc/llthosts file from one of the existing systems over to the new system. The /etc/llthosts file must be identical on all nodes in the cluster.
3. Create an /etc/llttab file on the new system. For example:

   set-node saturn
   set-cluster 101

   link bge1 /dev/bge:1 - ether - -
   link bge2 /dev/bge:2 - ether - -

   Except for the first line that refers to the node, the file resembles the /etc/llttab files on the existing nodes. The second line, the cluster ID, must be the same as in the existing nodes.

4. Use vi or another text editor to create the file /etc/gabtab on the new node. This file must contain a line that resembles the following example:

   /sbin/gabconfig -c -nN

   Where N represents the number of systems in the cluster including the new node. For a three-system cluster, N would equal 3.

5. Edit the /etc/gabtab file on each of the existing systems, changing the content to match the file on the new system.
6. For the following files on the new node:

   /etc/default/llt
   /etc/default/gab 
   /etc/default/vxfen
   /etc/default/vcs

   Verify if the attributes in each file are set as follows before using smf on Solaris 10 to start the related processes and to load drivers:

   LLT_START/LLT_STOP=1
   GAB_START/GAB_STOP=1
   VXFEN_START/VXFEN_STOP=1
   VCS_START/VCS_STOP=1

7. Use vi or another text editor to create the file /etc/VRTSvcs/conf/sysname on the new node. This file must contain the name of the new node added to the cluster.

   For example:

   saturn

8. Create the Unique Universal Identifier file /etc/vx/.uuids/clusuuid on the new node:

   # uuidconfig.pl -rsh -clus -copy \
   -from_sys galaxy -to_sys saturn

9. Start the LLT, GAB, and ODM drivers on the new node:

   For Solaris 10:

   # svcadm enable llt

   # svcadm enable gab

   # svcadm restart vxodm

10. On the new node, verify that the GAB port memberships are a and d:

    # gabconfig -a
    GAB Port Memberships
    ===============================================================
    Port a gen df204 membership 012
    Port d gen df207 membership 012
