Getting ready for the upgrade
Complete the following tasks before you perform the upgrade:
Review the Veritas InfoScale 7.4.2 Release Notes for any late-breaking information on upgrading your system.
Review the Veritas Technical Support website for additional information:
You can configure the Veritas Telemetry Collector while upgrading, if you have do not already have it configured. For more information, refer to the About telemetry data collection in InfoScale section in the Veritas Installation guide.
Make sure that the administrator who performs the upgrade has root access and a good knowledge of the operating system's administration.
Make sure that all users are logged off and that all major user applications are properly shut down.
Make sure that you have created a valid backup.
Ensure that you have enough file system space to upgrade. Identify where you want to copy the filesets, for example /packages/Veritas when the root file system has enough space or /var/tmp/packages if the /var file system has enough space.
Do not put the files on a file system that is inaccessible before running the upgrade script.
You can use a Veritas-supplied disc for the upgrade as long as modifications to the upgrade script are not required.
If /usr/local was originally created as a slice, modifications are required.
For any startup scripts in /etc/init.d/, comment out any application commands or processes that are known to hang if their file systems are not present.
Make sure that the current operating system supports version 7.4.2 of the product. If the operating system does not support it, plan for a staged upgrade.
Schedule sufficient outage time and downtime for the upgrade and any applications that use the Veritas InfoScale products. Depending on the configuration, the outage can take several hours.
Make sure that the file systems are clean before upgrading.
Upgrade arrays (if required).
To reliably save information on a mirrored disk, shut down the system and physically remove the mirrored disk. Removing the disk in this manner offers a failback point.
Make sure that DMP support for native stack is disabled (dmp_native_support=off). If DMP support for native stack is enabled (dmp_native_support=on), the installer may detect it and ask you to restart the system.
If you want to upgrade the application clusters that use CP server based fencing to version 6.1 and later, make sure that you first upgrade VCS or SFHA on the CP server systems to version 6.1 and later. And then, from 7.0.1 onwards, CP server supports only HTTPS based communication with its clients and IPM-based communication is no longer supported. CP server needs to be reconfigured if you upgrade the CP server with IPM-based CP server configured.
For instructions to upgrade VCS or SFHA on the CP server systems, refer to the relevant Configuration and Upgrade Guides.
