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
-
Log into the new system as superuser.
-
Create a directory in which to mount the software disc and mount the disc using the appropriate drive name. For example:
# mkdir -p /cdrom
# mount -V cdrfs -o ro /dev/cd
X /cdrom
where x is the device number.
-
Add
/opt/VRTS/bin
to your PATH
and /opt/VRTS/man
to your MANPATH
environment variables
See Setting PATH and MANPATH environment variables.
-
Change to the SFCFS directory.
# cd sfcfs
-
Run the
installsfcfs
script with -installonly
option to install all the required SFCFS packages on the new node.
# ./installsfcfs -installonly
-
Enter y to install SFCFS on these systems.
Do you want to install SFCFS on these systems? [y,n,q] (y)
-
Enter the system name of the new node to install SFCFS.
Enter the system names separted by spaces on which to install
SFCFS: system03
-
Enter a license key for system03.
Enter a SFCFS license key for system03:[?]
XXXX-XXXX-XXXX-XXXX-XXXX-X
-
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)
-
Enter
1
or 2
to be installed on all systems.
Select the filesets to be installed on all systems?
[1-2,q,?] (2)
-
Press Return to continue.
Press [Return] to continue:
Note
Do not reboot the machine now.
-
Create the
/etc/llttab
file the same as it looks on another node in the cluster.
-
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
-
Copy
/etc/llthosts
from one other node of the cluster and add a new line to it with the name of this node.
-
Copy the same
llthosts
file to all nodes of the cluster.
See /etc/llttab.
link en1 /dev/dlpi/en:1 - ether - -
link en2 /dev/dlpi/en:2 - ether - -
-
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.
-
Reboot the system that has been added.
# /usr/sbin/shutdown -r now
-
Start VxVM on the system that has been added.
# vxinstall
-
After starting VxVM, proceed to Configuring SFCFS and CVM agents on the new node.
