Upgrading everRun From Release 7.3.4.0 with a DVD
You can upgrade everRun software from everRun Release 7.3.4.0 to a later release a using a DVD.
Prerequisites:
- Before upgrading an everRun system, you should perform various system checks. For detailed information, access the Knowledge Base to search for the article Pre-upgrade system check for everRun (KB-4061). See Accessing Knowledge Base Articles.
- All PMs and VMs in must be in good health before performing an upgrade of the software. Before starting an upgrade, examine the everRun Availability Console to verify that there are no alerts indicating PM or VM problems.
- Eject any VCDs or USB media from the VMs before upgrading the software. If VCD or USB media is still connected to the VMs, it prevents the system from migrating the VMs and putting the PMs into maintenance mode for the upgrade process.
- Upgrading from Release 7.3.4 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 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.
