The following hardware components are required for OSCRO: Compaq ProLiant or ProSignia server For some server models, a knockout panel Two Compaq SMART-2 Array Controllers of the same type Compaq ProLiant Storage System(s)/F or /U Fast-Wide SCSI cables (either 6 or 12 feet in length) to connect...
OSCRO is supported only under Windows NT 4.0. All software required to implement OSCRO is on the Compaq SmartStart and Support Software CD included in the kit. This CD includes the Compaq Support Software for Microsoft Windows NT (SSD) (version 2.02 or later) and updated firmware and device drivers for the Compaq SMART-2 Array Controllers.
The ROMPaq for the SMART-2 firmware upgrade (version 1.94 or later) is included on the SmartStart and Support Software CD in the Recovery Server Option /U kit. It can also be found on the Compaq Web site. Kit Contents The Recovery Server Option /U kit (part number 304117-B21) includes...

......Elements of the Online Storage Recovery Option Solution The contents of the Recovery Server Option /U kit are illustrated in Figure 1-2.
With the introduction of OSCRO and its two-way switching capability, Compaq offers fault tolerance for mass storage controllers implemented at the hardware level, providing increased reliability without the need for complete I/O subsystem redundancy.
......Functionality and Configuration Options Merging two SMART-2 Controllers into a Controlled Pair OSCRO allows you to merge two matched SMART-2 controllers into a controller pair.
Page 21
OSCRO extends the reliability of Windows NT servers by ensuring continuing operation of the system, even when a mass storage controller fails. The Compaq Online Storage Controller Recovery Utility for Windows NT provides a means of managing the mass storage controllers of the entire Windows NT network from a single management station.
......Functionality and Configuration Options Configuration Options This section outlines the configuration guidelines involved in establishing highly reliable I/O using OSCRO.
Page 23
......SMART-2 Array Controllers implement RAID fault tolerance at the hardware level, eliminating the overhead associated with implementing RAID in the software.
The simplest OSCRO configuration involves two SMART-2 Array Controllers and a single ProLiant Storage System/F or /U equipped with the Recovery Server Switch. The Compaq Online Storage Controller Recovery Utility is used to merge the independent controllers into a controller pair. One controller is the active controller, and the other is designated the standby controller.

......ProLiant Storage System /F or /U Standby Active Device Driver Figure 2-2.
......Functionality and Configuration Options This configuration rule is especially significant when the system boot device is connected to a controller pair.
......2-10 Functionality and Configuration Options The number of possible controller pairs may be limited by the number of knockout panels or slots (see Figure 3-6) available on the server as well as the number of available expansion slots for SMART-2 controllers.
Hardware Planning The first step toward OSCRO implementation is hardware planning. You must have at least one Compaq ProLiant or ProSignia server, at least two SMART-2 Array Controllers of the same type, and at least one Compaq ProLiant Storage System/F or /U.
......Planning and Installing the Online Storage Controller CAUTION: SMART-2 Array Controllers use different disk geometries than standard SCSI adapters.
......OSCRO Planning Implications There are several things to consider before installing OSCRO. They include thinking about your current environment in terms of the following: The Recovery Server Option /U kit contains parts for three different high-availability option solutions.
......Planning and Installing the Online Storage Controller Potential Impact on Unattended Reboot Installation of OSCRO effectively sets up a standby mass storage controller.
Recovery Server Option Incompatibility Compaq Recovery Server Option consists of the Standby Recovery Server and the On-Line Recovery Server. OSCRO cannot be run in conjunction with either Recovery Server Option because both require hardware connectivity to ProLiant Storage Systems through the same interfaces and, although the cables are the same type, the cabling requirements are not compatible.
......Planning and Installing the Online Storage Controller These tasks, which should be performed in the order presented, are described in this section.

......Configuration Errors to Avoid Mismatched Controller Pairs OSCRO allows you to form multiple controller pairs in a single server. Each controller pair must conform to the configuration guidelines for single-channel or dual-channel controller pairs.
Wrong Device Driver If you get the message unknown error 0xed0e0000 you are running with old device drivers. Use the Compaq SSD for Windows NT that is included in the Recovery Server Option /U kit, to update the controller device drivers.
......Configuration Errors to Avoid Boot Device Considerations After a controller failover, there are situations in which the system will not be able to boot.
......Chapter 6 Recovering from Mass Storage Controller Failure OSCRO enables the server to continue operating even when a mass storage controller fails.
Page 71
Figure 6-1. Compaq PCI Hot Plug Technology Recovery from Controller Failure with OSCRO Using this procedure, the fault-tolerant state of the I/O subsystem is restored without shutting down the system or interrupting the availability of the data.
......Recovering from Mass Storage Controller Failure Without PCI Hot Plug Technology The steps for recovering from mass storage controller failure when you do not have PCI Hot Plug Technology are: Schedule a time when the server can be shut down.
Page 73
......Recoving from Mass Storage Controller Failure We strongly suggest you repair the boot device controller while the server is shut down.
Access the Online Storage Controller Recovery Utility from the Compaq Online Storage Recovery applet on the Control Panel, or from the Compaq System Tools folder. Highlight the controller pair you want to dissolve (the highlighted line must have a white icon).
