•
Setting for the remote management function is completed.
By using the remote management function, the connection between the Production Side and the Upgrade
Side by the remote KVM becomes possible during the Active Upgrade process. The setting of the
management LAN required for using the remote management function needs to be completed.
•
Restrict each user to a single session
is cancelled.
By OS default settings, the connection is restricted to one session per user. When you access the Upgrade
Side from the Production Side using a remote desktop under the split mode, the connection may fail due to
this restriction.

•
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 applications can result in downtime.
Important
•
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.
•
Can tolerate a potential decrease in performance during the upgrade.
For example, if load balancing is configured for LAN, there might be a decrease in network performance
when the system is split because the network adapters on the Upgrade Side lose access to the network.
(b) Storage requirements
•
Mirror volume (RAID-1)/RAID-5 volume are not configured in dynamic disk.
•
All internal hard disks must be configured with Rapid Disk Resync (RDR) and must be duplexed
(synchronized) before the Active Upgrade process starts.
•
The operating system boot volume and all active Windows operating system components must be located
on internal RDR disks.
This includes any volumes that contain paging (virtual memory) files for the operating system.
•
Any disk that contains software you want to upgrade cannot contain persistent data files for your
applications (those applications that will continue to run during the Active Upgrade process). Data file must
not reside on the same physical disk as a paging file.
You must store your data files on separate data disks.
•
Do not upgrade software on external storage devices.
External storage devices are always considered data disks. You cannot upgrade software on external
storage devices, as these devices not available to the Upgrade Side of the system while the system is in split
mode.
(3) Recommendations
When preparing your system for the Active Upgrade process, also consider the following recommendations:
•
Use static IP addresses for duplexed LAN.
•
If your system is protected by Windows Firewall, enable the exception for Active Upgrade Console as shown
in
Chapter 2 (1.5.2 (9) Configuring Windows Firewall for the Active Upgrade Process)
. If Windows Firewall is
running, and the exception for Active Upgrade Console is not enabled, communication between the
Production Side and Upgrade Side might fail during the Active Upgrade process.
