Configuring LLT, GAB, VCSMM, and VXFEN drivers

 To configure LLT, GAB, VCSMM, and VxFEN drivers

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

   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 systems in the cluster. For example, on saturn, enter:

   # scp galaxy:/etc/llthosts /etc/llthosts

3. Create an /etc/llttab file on the new system. For example:

   set-node saturn

   set-cluster 7

   link en1 /dev/dlpi/en:1 - ether --

   link en2 /dev/dlpi/en:2 - ether --

   Except for the first line that refers to the system, the file resembles the /etc/llttab files on the other two systems. The cluster ID must be the same as that for the existing cluster.

4. Use vi or another text editor to create the file /etc/gabtab on the new system. It should resemble the following example:

   /sbin/gabconfig -c -nN

   Where N represents the number of systems in the cluster. 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. Set up the /etc/vcsmmtab and /etc/vxfendg files on the new system by copying them from one of the other existing nodes:

   # rcp galaxy:/etc/vcsmmtab /etc

   # rcp galaxy:/etc/vxfendg /etc

7. Run the following commands to start LLT and GAB on the new node:

   # /etc/init.d/llt.rc start

   # /etc/init.d/gab.rc start

8. On the new node, start the VXFEN, VCSMM, and LMX drivers. Use the following commands in the order shown:

   # /etc/init.d/vxfen.rc start

   # /etc/init.d/vcsmm.rc start

   # /etc/init.d/lmx.rc start

9. On the new node, start the GMS and ODM drivers. Use the following commands in the order shown:

   # /etc/rc.d/rc2.d/S99odm start

10. On the new node, verify that the GAB port memberships are a, b, d, and o. All systems should be in the membership. Run the command:

    # /sbin/gabconfig -a

    GAB Port Memberships

    ===============================================================

    Port a gen 4a1c0001 membership 01

    Port b gen g8ty0002 membership 01

    Port d gen 40100001 membership 01

    Port o gen f1100002 membership 01
