Compaq ProLiant 1000 PCI Bus Numbering in a Microsoft Windows NT Environment - Page 12

PCI Bus Numbering in a Microsoft Windows NT Environment 12 where as, the Compaq Network Teaming and Configuration Utility supports Compaq 10/100 and Gigabit NICs, discussed in this document. Note: When configuration changes are necessary due to server maintenance or upgrade, Compaq recommends that you plan your changes carefully, document all original settings and bindings, and backup the system. Physical controller modifications made after the initial configuration can adversely affect the original bindings. To make the controller functional again, you must reset the controller and device driver bindings. Network controllers must bind to device drivers to be functional and provide connectivity on a network. System Administrators unaware that new bus number assignments were made after a configuration change might falsely believe that the hardware is broken. Compaq and Microsoft provide several utilities you can use to reset device driver and controller bindings. As long as the System Administrator knows bus numbers are assigned in a server, the Windows NT registry can be reset with minimal effort. See the section titled "PCI Test Configurations with ProLiant Servers" in this document. Disk Renumbering Disk reordering can complicate an administrator's ability to identify what a particular disk volume The Windows NT Disk Administrator located under Start#Programs#Administrative Tools (Common) contains a graphical tool provided with the operating system to manage disk drives. This tool contains when the numbers change allows Disk Administrators to display and track disk devices. Windows in Disk Administrator. However, NT lists drives and volumes in this utility in the order discovered at disk number reordering does not affect the contents of the disk volume. system startup. Each drive detected during discovery shows in the Disk Administrator with a disk number (starting at 0). The hard drive that boots the system must have one partition designated as the active partition and that loads as Disk 0. Compaq recommends running the Disk Administrator after completing a Windows NT installation to ensure that the boot drive receives a signature properly (Drive C:) and locks the drive letter to the partition. The Compaq SCSI and Array Disk Controllers have a Windows NT Registry entry used to determine disk controller-loading order. If disk numbers/drive letters become reordered because of a changed drive load order, the operation of the applications on the disk should not be affected. When you create a partition on a disk drive; Windows NT Disk Administrator should be run to permanently lock the drive letter to the partition even if Drive C: is the only disk in the system. In simple configurations, identifying contents on a particular drive or volume might not be an issue. In more complex configurations consisting of multiple drives and volumes, the order in which the drives/volumes are listed can change when a physical modification is made to the disk configuration. As mentioned earlier, Windows NT Disk Administrator lists drives and volumes in the order they are discovered. Disk ordering in a simple example: Order of detection (Before Change) Drive Letter and Label Disk 0 Disk 1 C: NT OS D: ACCT files 13UK-1200A-WWEN
