System Prerequisites
2-4 Express5800/320Fc: Active Upgrade™ User’s Guide
• Can tolerate a potential decrease in performance during the upgrade.
For example, if your system contains teamed network adapters that are configured
for load balancing or link aggregation, there might be a decrease in network
performance when the system is split because the network adapters on the
Upgrade Side lose access to the network.
• Are running Express5800/320Fc System Software Release 5.0 or higher.
• Have been updated with the latest firmware to support Active Upgrade technology,
including required BMC and VTM updates.
Furthermore, the Active Upgrade process has the following storage requirements:
• All internal hard disks must be configured with RDR and must be duplexed
(synchronized) before the upgrade process starts.
• The operating system boot volume and all active Windows operating system
components must be located on internal RDR disks. This includes any volumes
that contain paging (virtual memory) files for the operating system.
•
Any disk that contains software you want to upgrade cannot contain persistent
data files for your business-critical applications (those applications that continue to
run during the upgrade process). You must store your data files on separate data
disks , either internal or external. (Data volumes that reside on the same physical
disk as a system or paging volume are also not supported.)
•
External storage devices are always considered data disks. You cannot upgrade
software on external storage devices, as these devices not available to the
Upgrade Side of the system while the system is in split mode.
