5-106 Installing and Using Utilities
Prerequisites
Active Upgrade technology is supported only on NEC Express5800/ft series system that:
•
Are running in duplex mode prior to starting the upgrade process.
The CPU/IO modules must be duplexed, and all critical resources in the enclosures must be
duplexed.
A critical resource is a device (like a CPU, hard disk, or host bus adapter) that is necessary to
maintain fault tolerance. Non-fault-tolerant resources (like tape drives) connected to the system
will not affect the Active Upgrade process.
•
Contain duplexed 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/IO module .
Furthermore, at least one team of embedded Ethernet PCI adapters must have an active
network link in each CPU/IO module.
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, but it is recommended. The
readiness check in Active Upgrade Console will display a warning for each unteamed Ethernet
PCI adapter, but the warnings will not prevent you from proceeding with the Active Upgrade
process.
IMPORTANT:
•
An Ethernet team assigned to the virtual network by Hyper-V Virtual Network Manager
cannot be used in Active Upgrade.
To use Active Upgrade, at least two Ethernet teams are required.
•
If you need to modify Ethernet teams that are actively providing network connectivity,
this could impact network connectivity and should be scheduled to minimize impact to
your critical applications.
See "DUAL LAN CONFIGURATION" in Chapter 3, "Windows Setup and Operation" for
more information about configuring Ethernet PCI adapters and Ethernet teams.
•
Has one new IP address for Active Upgrade ready.
You need to prepare one IP address to communicate between the Production Side/the Upgrade
Side using PCI adapter during the Split. The IP address is allocated to the Upgrade Side
system with the Split status.
•
Do not use the devices connected with USB except the keyboard and mouse.
In Active Upgrade, if you are using the devices connected with USB other than the keyboard
and mouse, be sure to remove them physically before performing Active Upgrade.
