Installing Veritas Cluster Suite version 6.0.2 on RedHat Linux 6.4

VERITAS Cluster Server (VCS) from Symantec connects multiple, independent systems into a management framework for increased availability. Each system, or node, runs its own operating system and cooperates at the software level to form a cluster. VCS links commodity hardware with intelligent software to provide application failover and control. When a node or a monitored application fails, other nodes can take predefined actions to take over and bring up services elsewhere in the cluster.

Below are the efforts and challenges we had while Installing Veritas Cluster Suite on a Redhat Linux Server.

Pre-requisites for Installing Veritas Cluster Server Suite 6.0.2 on Redhat Linux 6.4

  1. 2 Nodes, RHEL6.4 in this case.
  2. 3 Nics on each node.
  3. Shared Storage.
  4. Add both node name in /etc/hosts file and they should be communicate between each other.
  5. VCS setup, I have used: VRTS_SF_HA_Soolutions_6.0.2_RHEL.tar

 Installation Steps include:

  1. The first thing is to copy the VCS setup file VRTS_SF_HA_Soolutions_6.0.2_RHEL.tar on one of the node and untar it.
  2. cd /dvd1-redhatlinux/rhel6_x86_64
  3. Run the installer script which sparks the installation
    vcs1

    Selected P, which will perform a Pre-Installation Check

    VCS installation

    I opted option 2 as it will install the Veritas Volume Manager also.

    vcs4

    Above RPMs failed, So the next step would be to install it on both the nodes

    vcs3-1

    Using the YUM Repository, I installed the missing packages.

    vcs5

    installed one of the missing rpm

    vcs6

    Restarted the Installation after installing missing rpms and it passed the pre-installation check after that. To continue with the installation I selected Y as it will automatically setup the communication between both nodes. Note: You have to setup ssh manually before starting the installation in case you are using the older version of Veritas Cluster Suite

    vcs6-1

    Selected Option 1 above

    vcs7

    I selected option 2 and it will install recommended RPMs by VCS

    vcs8

    Above RPMs will get installed on the system

    vcs9

    In above case, Veritas Cluster suite has failed to install VRTSvxfs rpm on both the nodes. But I didn’t opted to exit the installer. I will be installing the failed RPM later.

    vcs10

    Selected ST Standard HA in above screenshot

    vcs11

    The installation has been completed. Run the command /opt/VRTS/install/installsfha602 -configure in order to start configuring it.

    vcs12

    Opted not to enable I/O Fencing at this point of time

    vcs13

    Enter cluster name and cluster ID as per your choice

    vcs14

    Option 2 Selected

    vcs15

    Enter the network information as per your environment

    vcs16

    Enter username and password for the VCS

    vcs17

    vxportal, fdd and vxodm has been failed to start on both nodes

    vxportal, fdd and vxodm failed to start because of the rpm VRTSvxfs failed earlier during the installation. After digging around, we find out the reason is kernel incompatibility issues between the RHEL 6.4 and VCS 6.0.2. In order to fix it, we downloaded a patch from internet: https://sort.symantec.com/patch/detail/8227 and downloaded the patch fs-rhel6_x86_64-6.0.3.300-rpms.tar.gz

    vcs18

    unzipping the downloaded patch

    vcs19

    installed above rpm to fix the kernel incompatibility issue.

    vcs20

    configuring the VCS again after installing the patch fix

    vcs21

    vcs22

    vcs23

    VCS Configuration Completed successfully

    vcs23-1

    Check the status of the Cluster using hastatus -sum command

    The VCS Installation has been completed succesfull. You can login and verify cluster related information on any node using following commands.
    # lltconfig
    # lltstat -nvv |less                                                                                                    # gabconfig -a

Now, the cluster has been configured and try creating service group, disk group resource, volume, filesystem resource and application resource and see hows the cluster works.
