•
The application’s installation or upgrade utility does not involve changes to files or
databases on the data disks while the system is in split mode. (For example, the
utility cannot create new databases or convert existing data records to be
compatible with the new version of the application). The Upgrade Side has no
access to the data disks while the system is split.
Active Upgrade technology does not support the following types of upgrades:
•
Any upgrade that requires network connectivity during the upgrade process.
For example, you cannot use an installation program that downloads its installation
files from the Internet as the upgrade progresses. If possible, you must download
the complete installation package to the system prior to initiating split mode.
•
BIOS, BMC, or VTM firmware updates, which you can already perform while the
system is duplexed and online. See the Express5800/320Fc: User Guide
for more information.

System Prerequisites
Active Upgrade technology is supported only on Express5800/320Fc
systems that:
• Are running in duplex mode prior to starting the upgrade process.
The CPU- I ⁄ O enclosures must be duplexed, and all critical resources in the
enclosures must be duplexed.
A critical resource is a device (such as a CPU, hard disk, or host bus adapter) that
is necessary to maintain fault tolerance. Non-fault-tolerant resources (such as tape
drives) connected to the system do not affect the Active Upgrade process.
•
Contain teamed embedded Ethernet PCI adapters.
All embedded Ethernet PCI adapters must be teamed with the Intel PROSet utility,
and each Ethernet team must contain at least one Ethernet PCI adapter from each
CPU- I⁄ O enclosure. Furthermore, at least one team of embedded Ethernet PCI
adapters must have an active network link in each CPU- I⁄ O enclosure.
