System Prerequisites2-2 Express5800/320Fc: Active Upgrade™ User’s Guide• The application’s installation or upgrade utility does not involve changes to files ordatabases on the data disks while the system is in split mode. (For example, theutility cannot create new databases or convert existing data records to becompatible with the new version of the application). The Upgrade Side has noaccess 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 installationfiles from the Internet as the upgrade progresses. If possible, you must downloadthe complete installation package to the system prior to initiating split mode.• BIOS, BMC, or VTM firmware updates, which you can already perform while thesystem is duplexed and online. See the Express5800/320Fc: User Guidefor more information.Related Topics• Overview• “System Prerequisites”• “Recommendations” on page 2-5• “Managing Critical Applications During the Upgrade Process” on page 2-6• “Pre-Upgrade Tasks” on page 2-7System PrerequisitesActive Upgrade technology is supported only on Express5800/320Fcsystems 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 theenclosures must be duplexed.A critical resource is a device (such as a CPU, hard disk, or host bus adapter) thatis necessary to maintain fault tolerance. Non-fault-tolerant resources (such as tapedrives) 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 eachCPU- I ⁄ O enclosure. Furthermore, at least one team of embedded Ethernet PCIadapters must have an active network link in each CPU- I ⁄ O enclosure.
