VCS cluster 6.2 LAB : Installing VCS

If you have followed the first 4 posts of this series then you are ready to install the SFHA on the 2 nodes. We would also configure the I/O fencing using the installer. Unlike older version the I/O fencing can be configured with the help of installer. We don’t even have to initialize the disks or create diskgroup for fencing.

Makes sure you have fulfilled all the pre-requisites before proceeding with the installation. Download the trialware from the Symantec website which can be installed using the keyless licensing option. First, copy the installation media to the VM node01. Extract the contents and run the installer.

[root@node01 tmp]# gzip -d VRTS_SF_HA_Solutions_6.2_RHEL.tar.gz
[root@node01 tmp]# tar -xvf VRTS_SF_HA_Solutions_6.2_RHEL.tar
[root@node01 tmp]# cd /dvd1-redhatlinux/rhel6_x86_64
[root@node01 tmp]# ./installer

Select the install and upgrade option (I).

Select SFHA as the product to be installed.

Select Install recommended rpms option and specify the nodes in the clsuter.

Installer would run some pre-checks. If there are any missing dependent rpms like pam, glibc etc, it would notify the same. If you have configured the public yum repo properly, the installer would install the missing rpms for you.

After successful installation of SFHA rpms, installer would ask for the license keys, for which we would choose the keyless licensing.

The next screen would be about I/O fencing and cluster related information like cluster name, ID and information about llt links.

We would not configure any virtual IP for the cluster.

Configure the cluster in secure mode. Do not enable SNMP and SMTP notifications. The cluster would stop and start SFHA processes after this to reconfigure SFHA. The next step is to configure fencing.

After the configuration of fencing, installer would restart the SFHA processes again. This would complete the installation of SFHA on 2 nodes of OEL. Check the hastatus and gabconfig output to verify the same.

[root@node01 ~]# hastatus -sum
