The results of executing RDACUninsUtil are similar to performing the Windows "Add or Remove Programs" RDAC driver uninstaller. RDACUninstUtil's intended use is for uninstalling disk and bus driver registry entries after an unexpected interruption of the uninstall or install of RDAC driver. A failed RDAC driver uninstall/install can result in a failed reboot of the Windows Operating System. In addition to removing RDAC disk/bus registry entries in the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet, RDACUninstUtil supports the same actions on a failed system hive. In the case where a Windows reboot after RDAC driver uninstall results in a blue screen, the failed Operating System disk can be attached to a similar Windows system and repaired by specifying the location of the failed system hive. IMPORTANT: Due to an uninstall problem in Windows RDAC v8.4 driver on SAN boot (root boot) Windows 2000 systems, RDACUninstUtil.exe must be executed prior to performing uninstall of RDAC driver via Windows "Add or Remove Programs". After the RDACUninstUtil.exe utility has finished execution, complete RDAC driver uninstall by executing the "Add or Remove Programs" uninstaller. Failure to run this utility before uninstalling the RDAC driver might result in Windows system blue-screen during server reboot. Before using RDACUninstUtil.exe read the help information accessed by entering RDACUninstUtil ? at a command window prompt. 1.2 Limitations 1. RDACUninstUtil.exe does not repair installer application registry entries or history files. After an interrupted RDAC driver installation or uninstallation, it is necessary to check "Add or Remove Programs" for an existing RDAC driver uninstaller. If the uninstaller exists, it must be executed following use of RDACUninstUtil.exe utility. 2. RDACUninstUtil.exe utility supports the Microsoft Windows 2000 and Windows Server 2003 32bit and IA64 edition operating systems only. The RDACUninstUtil.exe utility for Microsoft Windows Server 2003 IA64 edition must not be executed on an AMD64 or EM64T servers. 1.3 Enhancements N/A 1.4 Level of Recommendations and Prerequisites for the update: N/A 1.5 Dependencies: The following code levels must be used. Deviations from the listed code levels are not supported. 1. RDACUninstUtil.exe is supported for the uninstallation of RDAC driver versions 8.4 and above. The IBM FAStT Storage Manager RDAC driver version 8.4 is installed as a single package. In the later versions of the IBM DS4000 Storage Manager, the RDAC driver is included in the IBM DS4000 Storage Manager installer package. 2.0 Change History -------------------- Version 09.01.35.12 - 06/29/2005 - This is the initial release of the IBM TotalStorage� DS4000 RDACUninstUtil.exe. This utility is required to be run before the uninstallation of the RDAC driver version 8.4x in servers that are in SAN boot (root boot) environment. 3.0 Installation and Setup Instructions ----------------------------------------- 3.1 Prerequisites N/A 3.2 Installation RDACUninstUtil.exe is a command line utility. Refer to the help information provided with the utility. Help information is accessed by entering RDACUninstUtil ? at a Microsoft Windows command prompt window. 3.3 Usage Note: You MUST be logged on as local Administrator to run RDACUninstUtil utility. Open the Microsoft command prompt window and enter either the following command RDACUninstUtil [-l logname] [-f hivename] or RDACUninstUtil [-l:logname] [-f:hivename] where the Options / Parameters are as follows: -l logname = the file path and name where you would like the RDACUninstUtil log saved. If this option is not entered, a log will not be written. The directory path and directory where the log is to be saved, must exist prior to running RDACUninstUtil. -f hivename = the file path and name of the SYSTEM Hive to be repaired. The SYSTEM Hive, in this case, is not the local system's hive but is a hive copied from a different system or located in an attached system disk. The location of a SYSTEM Hive can be found at: drive:(WINDOWS or WINNT)\system32\config\system. ex: C:\WINDOWS\system32\config\system C:\WINNT\system32\config\system If this option is not entered, the local system's HKEY_LOCAL_MACHINE SYSTEM key will be the target of the repair. Examples: RDACUninstUtil -l C:\regrepair.txt -f E:\WINDOWS\system32\config\system The above command will repair the SYSTEM Hive located at E:\WINDOWS\system32\config\system and log status/errors to C:\regrepair.txt. RDACUninstUtil -f D:\Temp\badsystem The above command will repair the SYSTEM Hive that was copied from a different system and renamed 'ba
