Chapter 2 Installing Bundled Software
(1) Software Upgrade Support
Active Upgrade technology supports the installation or upgrade of application software that meets the following
criteria:
•
The application’s executable files, configuration files, and temporary files (for example, cache files) reside on
internal system disks that are mirrored with RDR.
•
The application’s data files reside on data disks.
Data volumes that reside on the same physical disk as a system volume are not supported.
•
The application’s installation or upgrade utility does not involve changes to files or data on the data disks
while performing upgrade (the system is in split mode).
The Upgrade Side has no access to the data disks while the system is split.
•
You must download the software upgrade package to the system before initiating split mode. Network
connection is disabled during upgrade because the system is in split mode.
•
BIOS, BMC firmware updates are unavailable.
(2) Prerequisites
To use Active Upgrade, the following conditions must be satisfied:
(a) Prerequisites on Express5800/ft series
•
In the environment where the backup software such as ARCServe and BackupExec is installed, ensure to
stop the backup software service before performing Active Upgrade.
•
When BackupExec is installed, Upgrade Side must be restarted after Split is completed.
•
The CPU/IO modules must be duplexed, and running in duplex mode prior to starting the upgrade process.
•
Embedded LAN must be duplexed.
Embedded LANs must be duplexed between LAN ports of each CPU/IO module, and must have an active
network link in each CPU/IO module.
•
You do not need to duplex optional LAN cards, but it is recommended. The readiness check in Active
Upgrade Console will display a warning for each non-duplexed LAN cards, but the warnings will not prevent
you from proceeding with the Active Upgrade process.
Important
•
To use Active Upgrade, a duplexed LAN not assigned to the virtual network by
Hyper-V is required.
•
If you need to modify duplexed LAN that are actively providing network
connectivity, this could affect network connectivity and should be scheduled to
minimize impact to your applications.
Tips
See
Chapter 1 (3.9 Duplex LAN Configuration)
for more information.
•
Has one new IP address for Active Upgrade ready.
You need to prepare one IP address to communicate between the Production Side and the Upgrade Side
via LAN 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, mouse, and server switch unit.
In Active Upgrade, if you are using the devices connected with USB other than the keyboard, mouse, and
server switch unit, be sure to remove them physically before performing Active Upgrade.
