About SFCFSHA upgrade support using YUM
SFCFSHA version 9.0 introduces support for a new upgrade method using the Yellow-Dog Updater Modified (YUM) tool. This method is designed to work along with the operating system (OS) minor version upgrades and application upgrades. The YUM upgrade method uses a single node reboot to complete the upgrade process, with no application downtime or a need to evacuate the Cluster Server (VCS) resource, if applicable.
The YUM upgrade method is an additional way to upgrade SFCFSHA. This method does not require the use of the SFCFSHA installer. The other upgrade methods, for example with the Common Product Installer (CPI), continue to be supported.
Consider the following requirements and limitations before you use YUM to upgrade SFCFSHA:
YUM support for SFCFSHA upgrade is available on the RHEL platform only.
Upgrades are supported for SFCFSHA version 8.x to 9.x only.
Upgrades for older SFCFSHA versions (7.4.x onward) are not supported using the YUM tool.
Rollback (yum history rollback and yum history undo) is not supported.
Rolling or full upgrades are supported with this method.
The Dandified YUM (DNF) is a successor to YUM and uses a similar command structure. The upgrade process that is described here works with both YUM and the DNF commands.
In a pre-reboot phase where you have run the yum update command but have not yet rebooted the node, SFCFSHA continues to work as the previous version. New features and functionality of the upgraded SFCFSHA version are not available.
The pre-reboot phase may also enforce other restrictions. For example, you cannot update the VxVM tunables.
If the following services are not running before you run the yum update command, then ensure that you do not restart these services before a node reboot (during the pre-reboot phase):
vxfs service
vxodm service
vxgms service
vxglm service
veki service
All Secure File System (SecureFS) and VFR scheduled jobs are skipped for the time duration that it takes for the yum update command to complete. After the update process is complete, the jobs resume and run as per the configured schedule.
