Upgrading a System To Release 7.4.x with a DVD

You can upgrade a system, with or without external storage, from everRun Release 7.3.4.0 to Release 7.4.x using a DVD.

Caution: If your system has external storage, you must call Stratus Customer Assistance to perform an upgrade to everRun Release 7.4.x.

Prerequisites:

All PMs and VMs in must be in good health before performing an upgrade of everRun software. Before starting an upgrade, examine the everRun Availability Console to verify that there are no alerts indicating PM or VM problems.
Upgrading from Release 7.3.4 to 7.4.x requires up to 10GiB of additional disk space for the LVM physical volume that is on the boot disk. Before you begin the upgrade, make sure that your system has at least 10GiB of additional disk space.

Note: Upgrading from Release 7.3.4 to 7.4.x may take approximately two hours depending on the complexity of your configuration. You cannot use the everRun Availability Console while the upgrade is in progress, but the everRun Availability Console may display informational or error messages as part of the procedure.

The procedure includes shutting down VMs and then sequentially on each node: putting the node in maintenance mode, shutting down the node, powering on the node and using the BIOS setup utility to boot from DVD and then recover the node. Note that you cannot use the UEFI setup utility to upgrade from a DVD.
