I cannot upgrade from Dell OpenManage 4.2 to the latest version of Dell OpenManage without
uninstalling and losing my
managed system software settings. Is there a way to upgrade to the latest
version while preserving my
managed system software settings?
Yes, but you must upgrade from Dell OpenManage version 4.2 to 4.3 first, before upgrading to a later
version of Dell OpenManage. If you are working with Windows Server
™ 2003, do not apply Service Pack
1 until you have completed the Dell OpenManage upgrade.
How do I perform an unattended operating system installation with the Installation and Systems
Management CD?
You can install a Windows operating system on many systems using identical settings, which allows
consistent configurations across all systems. To use this feature, it is necessary that the target Dell
PowerEdge™ systems be configured identically, with the same hardware and operating system
components. Any difference in configuration makes the replication feature unusable.
To perform unattended installations, do the following:
1
On the first system that is set up, ensure that the system’s BIOS is set to boot from the CD. Insert the
Dell PowerEdge Installation and Server Management CD and reboot your system. Follow the
installation interview, which includes setting the date and time, configuring the RAID controllers,
selecting the operating system and specifying its settings, configuring the hard drive, entering the
network settings, and configuring Windows. If any information is omitted, an unattended installation
can still be accomplished, but the system will prompt you for the missing information.
2 In the Installation Summary window, select Save Unattended Installation Script at
C:\unattended.txt, C:\txtsetup.oem
and select Save Profile for Replication at C:\replication. Click
the
Continue button.
3 Insert the appropriate operating system CD and follow the instructions to complete the installation.
Reboot the system to complete the installation.
4 When the installation is complete on the first server, copy the files from the C:\replication directory to
a diskette.
5 For each subsequent unattended installation, insert the disk containing the replication files into the
diskette drive and boot the system. The installation interview will be done automatically. Then, insert
the operating system CD to install the operating system, and reboot the system to complete the
installation.
What is the best way to use the Prerequisite Checker information?
The Prerequisite Checker is available for Windows. See the readme file
\srvadmin\windows\PreReqChecker\readme.txt on the Dell PowerEdge Installation and Server
Management CD for detailed information about how to use the Prerequisite Checker.
