Adding a node to a cluster

If you want to add a new node to a multi-node cluster, first prepare the new system hardware. Physically connect the new system to the cluster using private networks and attach to any shared storage. Then install the required OS software.

See Cluster platforms.

 To add a node to a cluster

1. Log into the new system as superuser.
2. If Solaris volume management software is running on your system, the software disc automatically mounts as /cdrom/cdrom0.

   If Solaris volume management software is not available to mount the DVD, you must mount it manually. After inserting the software disc, enter:

   # mount -F hsfs -o ro /dev/dsk/c0t6d0s2 /cdrom

   where c0t6d0s2 is the default address for the disc drive.

3. Add /opt/VRTS/bin to your PATH and /opt/VRTS/man to your MANPATH environment variables

   See Setting PATH and MANPATH environment variables.

4. Change to the SFCFS directory.

   # cd sfcfs

5. Run the installsfcfs script with -installonly option to install all the required SFCFS packages on the new node.

   # ./installsfcfs -installonly

6. Enter y to install SFCFS on these systems.

   Do you want to install SFCFS on these systems? [y,n,q] (y)

7. Enter the system name of the new node to install SFCFS.

   Enter the system names separted by spaces on which to install
   SFCFS: system03

8. Enter a license key for system03.

   Enter a SFCFS license key for system03:[?]
   XXXX-XXXX-XXXX-XXXX-XXXX-X

9. Enter y or n for another license key. You are prompted to press Return to continue.

   Do you want to enter another license key for system03?

   [y,n,q,?] (n)

10. Enter 1 or 2 to be installed on all systems.

Select the packages to be installed on all systems?

[1-2,q,?] (2)

11. Press Return to continue.

    Press [Return] to continue:

    ---

      Note   Do not reboot the machine now.

    ---

12. Create the /etc/llttab file the same as it looks on another node in the cluster.
    1. Change the set-node line to the name of the new node and specify that the LAN ports for the public and private networks are configured the same as on the other cluster nodes:

       set-node system03

       set-cluster 100

       link lan2 /dev/lan:2 - ether - -

       link lan0 /dev/lan:0 - ether - -

    2. Copy /etc/llthosts from one other node of the cluster and add a new line to it with the name of this node.
    3. Copy the same llthosts file to all nodes of the cluster.

       See /etc/llttab.

13. Create /etc/gabtab file the same as it is on another node in the cluster. See /etc/gabtab.

    For example,

    /sbin/gabconfig -c -n 3

    There is no need to reboot the other nodes, just update the /etc/gabtab file on the other nodes in the cluster.

14. Reboot the system that has been added.

    # /usr/sbin/shutdown -R -y 0

15. Start VxVM on the system that has been added.

    # vxinstall

16. After starting VxVM, proceed to Configuring SFCFS and CVM agents on the new node.
