may now push in the controller once removed after activity has been taken over by the existing controller. The controller may take a couple of seconds before the controllers finish initializing and assume their load. 2. Failover by "Forcing controller failure" Select "View and Edit Peripheral Devices," "Set Peripheral Device Entry," and "Redundant Controller Primary/Secondary." Select "Force Primary/ Secondary Controller Failure." You may now pull out the controller you had just disabled. I/Os should be continued by the existing controller. Continue the aforementioned procedure to complete the test. WARNING! • This function should only be performed for testing the redundant controller functionality before any critical data is committed to drives. Although the controller is designed to be hot-swappable, unpredictable failures may occur during the process, i.e. improper handling of PCB boards while replacing controllers.

Chapter 13 In-band SCSI Text RAID Manager and SNMP Agent Installation 13.1 In-band SCSI Text RAID Manager The Text RAID Manager software offers the same functionality as the VT-100 terminal emulation. Instead of communicating via an RS-232C connection, the program communicates with the RAID controller over the SCSI bus. This is especially useful when you want to ready a RAID system before using the Java-based RAID manager. In-band SCSI technology translates the original commands into standard SCSI commands. These SCSI commands are then sent to and received from the SCSI RAID controller. The Text RAID Manager is thus able to administrate the RAID controller. The Text RAID Manager supports both local and remote management of Infortrend external disk array controllers. Local management refers to management of the disk array from a local host − management transactions traverse the SCSI bus connected between the controller and the host’s SCSI adapter. Remote management refers to management of the disk array from a remote station connected to the controller through a network cable. Typically, management will be done locally. A local host runs the Text RAID Manager to configure and monitor the connected controller. Local management is simpler than remote management in that it requires less hardware in its configuration. Remote management is more complicated than local management but provides the following benefit: • Arrays can be managed from distant and remote locations. Since remote management utilizes network cable or the telephone line, management from anywhere around the globe is possible. All that is needed is a simple attachment to an existing network where the disk array’s host exists. Depending on your specific needs and configuration requirements, you may perform management either from a local host or from a remote station. The following sections describe how to set up your hardware for local and remote management. In-band Text RAID Manager and SNMP Agent Installation 13-1
