Chapter 3 CR3500 Configuration Utility This chapter provides instructions for using the Compaq CR3500 Configuration Utility and describes methods to configure your CR3500 controller quickly and easily. The CR3500 Configuration Utility is located on the Compaq SmartStart and Support Software CD. The utility uses a graphical user interface (GUI) to help you configure the CR3500 controller. You can use the utility to configure a controller initially or to reconfigure a controller. The CR3500 Configuration Utility can create arrays (a group of physical drives that are similar in size) called logical drives. Logical drives are created using the CR3500 Configuration Utility's Add Logical Drive Wizard. You can create: s s s s s s Single-device arrays (JBODs) Striped arrays (RAID 0) Mirrored arrays (RAID 1) Striped mirrored arrays (RAID 0+1) Striped parity arrays with fixed parity disk (RAID 4) Striped parity arrays with floating parity disk (RAID 5) For more information on RAID levels, refer to the Online Help. 3-2 Compaq ProLiant CL1850 Software User Guide This chapter includes the following sections: s s s s s Online Help Before You Begin CR3500 Configuration Utility Features Configuration Procedures Error and Warning Messages The CR3500 Configuration Utility: s s Uses easy-to-understand graphics to illustrate controller configuration Uses a wizard that guides you through the configuration process Online Help Press the F1 key to activate context-sensitive, online help for each screen. Help is also available by clicking the Help heading on the toolbar. A status bar at the bottom of the screen also displays help messages describing the current selection. Before You Begin Before a first-time installation and configuration of the system, complete the following: s Install a redundant CR3500 controller (optional). To install a redundant CR3500 controller, refer to the Compaq ProLiant CL1850 User Guide. Determine which fault tolerance method and logical drive configuration you want to use. For more information on RAID levels, refer to the Online Help. s CR3500 Configuration Utility 3-3 CR3500 Configuration Utility Features There are two methods you can use to run the CR3500 Configuration Utility. s SCSI connection--This option is only for systems running Windows NT. Serial cable connection--For server nodes not running Windows NT, a separate system running Windows 95/98/NT is required. A serial cable is used to connect the separate system to the CR3500 RAID controller through a connection in the back of the shared storage area. s SCSI Connection The system must be running Windows NT to connect online via the SCSI interface. Insert the SmartStart CD into the server node. From Windows NT Explorer, go to the CR3500 directory on the SmartStart CD and run SETUP. EXE. This will install the CR3500 Configuration Utility to the server node. Go to Start, Compaq System Tools, CR3500 Utility to run the utility. A connection window appears (Figure 3-1). Figure 3-1.

An attempted restoration of the files from server node 1 may fail if the tape backup software is unable to comprehend the shared characteristic of drive G:. Second, if a failover or failback event occurs while a backup is executing, you may not be able to continue the backup; you may be required to restart the backup from the beginning. For example, if you are backing up drive G: from server node 1 and a failover event moves drive G: to server node 2, the backup process will abort since drive G: is no longer accessible from server node 1.
