About support for InfoScale upgrade using YUM
InfoScale (9.0 onwards) provides an additional method to upgrade the product using the Yellowdog Updater Modified (YUM) tool. This method does not require the use of the InfoScale Common Product Installer (CPI). The YUM upgrade method is designed to accommodate minor OS version upgrades as well as application upgrades.
This method employs a single-node reboot to finalize the upgrade process, thus eliminating application downtime and the need to evacuate the Cluster Server (VCS) resource, if applicable.
Consider the following requirements and limitations before you use YUM to upgrade InfoScale:
The YUM upgrade method is available on the RHEL platform only.
With InfoScale 9.0, the method supports upgrades from InfoScale 8.x to 9.x only.
With InfoScale 9.0.2, the method supports upgrades from InfoScale 7.4.x to 9.x. Specifically, you can upgrade from the 7.4.1.3100, 7.4.1.3300 (additional patch for RHEL 8.7), and 7.4.2.5600 patches through 9.x.
The method supports rolling upgrades or full upgrades.
The method does not support rollback operations like yum history rollback and yum history undo.
The method is compatible with YUM and DNF commands, both. Dandified YUM (DNF) is a successor to YUM and employs a similar command structure.
In the pre-reboot phase, where you have run the yum update command but have not yet rebooted the node, InfoScale continues to work as the previous version. The features and functionality of the upgraded InfoScale version are not available until the node has rebooted successfully.
The pre-reboot phase may also enforce other restrictions. For example, in InfoScale storage environments, you cannot update the VxVM tunables.
During the pre-reboot phase, if the following services are not running before you run the yum update command, make sure that you do not start them before the node reboots:
veki
vxfs
vxglmservice
vxgmsservice
vxodm
During the execution of the yum update command, any scheduled Secure File System (SecureFS) jobs and File Replicator (VFR) jobs are temporarily skipped. After the command completes its execution successfully, the jobs resume and run as per the configured schedule.
