Preparing the Host System Hsz/HsxDisk Driver Note: HsxDisk refers to the Windows 2000 device driver. HszDisk refers to the Windows NT device driver. The Hsz/HsxDisk driver works with the Hsz/HSG-family of RAID controllers to enhance the Windows 2000/Windows NT online storage availability and fault-tolerance. Hsz/HsxDisk works in single-host and cluster environments to maintain optimum subsystem performance during storageset error recovery conditions (For example: the failure of a RAID 3/5 or mirrorset drive member). Hsz/HsxDisk also works in single-host and cluster environments to assist the subsystem during controller failover and failback operations. In Windows NT/Windows 2000 cluster environments, Hsz/HsxDisk works to facilitate Hsz/HSG-based storageset migration during host failover and failback events. Hsz/HsxDisk services Hsz and HSG based storage devices and does not affect the operation or performance of other storage devices on the system. The driver uses of the Windows NT/Windows 2000 system event log and posts error and informational events when required. If the driver loads successfully during boot time, it posts an informational message in the log reporting that it claimed available Hsz- and HSG-based storagesets. Fibre Channel Software Setup utility supports driver un-installation with Windows NT 4.0 or Windows 2000. Hsz/HsxDisk may be uninstalled using the Add/Remove program applet from the control panel. However, you should not uninstall the driver unless you have disconnected the subsystem from the servers. HSG-family RAID controllers should never be installed without Hsz/HsxDisk.sys configured. FCA Driver Support The FCA is the PCI Fibre Channel adapter that is supported with the Enterprise Modular Storage RAID Array Fibre Channel RAID System. Because the Fibre Channel utility can only modify existing FCA registry settings, the driver from the supplied floppy must be installed prior to running the Fibre Channel Setup Utility. The Fibre Channel Setup Utility changes the FCA driver registry settings and copies an updated version of the driver to the driver's directory to ensure proper operational use of the FCA Fibre Channel host adapter with the Enterprise Storage 110 HSG80 ACS Solution Software V8.8 for Windows NT, Windows 2000, and Windows Server 2003 (32-bit) Installation and Configuration Guide
