System Prerequisites

All ports on any dual-port adapter must be either teamed or not teamed. You cannot have only one port on an adapter teamed.

You do not need to team non-embedded Ethernet PCI adapters for the Active Upgrade process, but it is best to do so to ensure that the network connectivity provided by these adapters continues to be available throughout the upgrade process. The readiness check in Active Upgrade console displays a warning for each unteamed Ethernet PCI adapter, but the warnings do not prevent you from proceeding with the upgrade process.

N O T E

If you modify the configuration of your Ethernet PCI adapters and Ethernet teams to meet these prerequisites, it could impact network connectivity for the system. You should schedule this work to minimize impact to your critical applications.

See the Express5800/320Fc: User Guide for more information about configuring Ethernet PCI adapters and Ethernet teams.

•Contain Virtual Technician Modules (VTMs).

The VTMs provide the connection between the Production Side and Upgrade Side during the Active Upgrade process. Both VTMs must be configured properly and connected to the same subnetwork, preferably on a dedicated maintenance network.

•Can tolerate running in simplex mode for a brief period during the upgrade.

Because each side of the system runs in simplex mode during the upgrade, an interruption on the side that is actively running your critical applications can result in downtime.

!C A U T I O N

You cannot restart the operating system on the Production Side during an upgrade (though you can restart the Upgrade Side as many times as necessary.) Also, it is unsafe to pull an enclosure from a split-mode, simplexed system because doing so terminates all processes running on that enclosure.
