InfoScale™ 9.0 Cluster Server Configuration and Upgrade Guide - Linux

To upgrade VCS with the yum tool

1. Configure a VCS repository on a node.

   • Create a repository file (.repo) under /etc/yum.repos.d.

     Run the following command:

     # cat /etc/yum.repos.d/infoscale90.repo

   • Add the following contents to the repository file:

     [repo-VCS9.0]
     name=Repository for VCS 9.0
     baseurl=file:///<image_dir>/rpms/
     enabled=1
     gpgcheck=1
     gpgkey=file:///<image_dir>/rpms/RPM-GPG-KEY-veritas-infoscale

     The values for the baseurl attribute can start with http://, ftp://, or file:///. The URL you choose should be able to access the repodata directory. It also needs to access all the VCS RPMs in the repository that you create or update.

   • Save the changes and exit the file editor.

   • Update the yum repository.

     Run the following commands:

     # yum repoList

     # yum updateinfo

2. If applicable, perform a minor OS version upgrade as follows:

   • Disable the VCS repo.

     Run the following command:

     # yum update --disablerepo=[Infoscale repo]

   • Update the operating system minor version.

3. Temporarily freeze the Cluster Volume Manager (CVM) and other service groups that contain the CVMVoldg or DiskGroup resources, or forcefully stop the Cluster Server (VCS) high availability daemon HAD.

   Run the following commands:

   # /opt/VRTSvcs/bin/hagrp -freeze cvm

   # /opt/VRTSvcs/bin/hagrp -freeze <service_group>

   Or,

   # /opt/VRTSvcs/bin/hastop -local -force

4. Upgrade VCS.

   Run the following command to update the VCS rpms:

   # yum update VRTS*

   Note:

   Arctera recommends that you update the OS and the VCS rpms separately.

5. Unfreeze the service groups or start HAD, if you had stopped the daemon earlier in step 3.

   Run the following commands:

   # /opt/VRTSvcs/bin/hagrp -unfreeze cvm

   # /opt/VRTSvcs/bin/hagrp -unfreeze <service_group>

   Or,

   # /opt/VRTSvcs/bin/hastart

6. Run the following command to manually generate and install the installer scripts for configuration:

   # /opt/VRTS/install/bin/UXRT9.0/add_install_scripts

7. Reboot the cluster nodes, one node at a time.

   Do the following:

   • Before you reboot a node, ensure that you fail over the application service group to an alternative cluster node.

     Run the following commands on the node you want to reboot:

     # /opt/VRTSvcs/bin/hagrp -switch <app_service_group> -to <alternate_node_name>

   • Stop the VCS high availability daemon (HAD) locally on the node.

     Run the following command:

     # /opt/VRTSvcs/bin/hastop -local

   • Gracefully reboot that node.

     Run the following command:

     # shutdown -r now

   • Repeat these steps on each subsequent node.

8. Repeat steps 1 to 7 on each VCS cluster node, one node at a time.
9. After all the nodes are upgraded, update the Cluster Server (VCS) protocol version from any one node in the cluster.

   Run the following command:

   # /opt/VRTSvcs/bin/haclus -version -update 9.0.0.0000

10. Update the type definition from any one node in the cluster.

    Run the following command:

    # /opt/VRTSvcs/bin/hatrigger -updatetypes 1 <node_name> 1

11. Update the CVM protocol version, the disk group version, and the file system disk group layout version (DLV).

    Run the following commands:

    # vxdctl upgrade

    # vxdg upgrade <diskgroup>

    # vxupgrade <mount_point>
