Connecting Two RS700s into a SCSI Channel (for TR102/RM102 only) To connect two RS700s into one host server: 1. Remove a screw to open the top panel of the enclosure . 2. Disable the terminator of the SCSI expander in the first RS700. The terminator of the SCSI expander in the second RS700 should be enabled. Connect the external SCSI cable to the SCSI Out port of the first RS700 to the SCSI In port of the second RS700. Change the ID number of channel Ch0 of the AA3102RS RAID controller in the first RS700 to 0 and the ID number of channel Ch0 of the AA3102RS RAID controller in the second RS700 to 1 to avoid system conflicts. Please refer to AA3102RS RAID Controller User's Guide for more information and also refer to Appendix B for the Channel Connection Setup Table. 3. 4. 20 Host Server HBA Second RS700 Storage Enclosure First RS700 Storage Enclosure Chapter 4 Removing and Installing the Enclosure Panels Before touching any electrical equipment, ground yourself by touching the metal part of your computer chassis. This discharges any static electricity and will prevent any damage to your computer. Removing the Left and Right Panels 1. Slowly pull out both of the panels. 4. To reinstall the left and right panels, simply reverse the procedures discussed above. 22 Installing the Enclosure Frame 1. After removing the left and right panels, remove the screws located on the four corners of the enclosure. Gently pull out the entire frame to access the inside components. 2. To reattached the enclosure frame, simply reverse the procedures discussed above. 23 Chapter 5 Introduction Cluster Server Connection A cluster is a group of independent network servers that present themselves to a network as a single system. MSCS (Microsoft Cluster Server) clustering provides three main benefits: 1. In most cases, connecting RD, TD and SG are enough to establish communication with a terminal. If you are using a PC as a terminal, any VT-100 terminal emulation software will suffice. Microsoft Windows includes a terminal emulation program as presented with the "T" terminal" icon in the Accessories window. · · 4. Building a RAID System Drive. The following figure is a basic flowchart when configuring a RAID system. Hardware installation must be completed before any configurations take place. Create Logical Drive Partition Logical Drive Map Host LUN (System Drive) When power is turned on, the AcerAltos 3102RS RAID box scans all the hard drives that are on all the drive channels. If a hard drive was connected after the controller completes initialization, use the "SCAN SCSI DRIVE" function to let the controller recognize the newly added hard drive and configure it as a member of a logical drive or a spare drive. In accordance to your requirement, configure a logical drive to contain one or more hard drives based on the desired RAID level, and partition the logical drive into one or several partitions. The host SCSI adapter will recognize the system drives after re-scanning the host SCSI bus. 33 Since the controller is totally operating system independent, the operating system of the host computer will not be able to find out whether the attached devices are physical hard drives or virtual system drives created by the RAID controller. A `Logical Drive" is a set of drives grouped together to operate under a given RAID level and appears as a single contiguous drive. The 3102RS RAID Box is capable of grouping connected drives to as many as 8 logical drives, each configured on the same or different RAID levels. A logical drive can be further divided into a maximum of 8 "Partitions". [. . . ] The controller has comprehensive drive failure management that allows automatic reassignment of reserved blocks when a bad sector is encountered during a write. Hot-swapping is supported through automatic disconnection of a failed drive and detection of a reserved drive followed with background building of data. What is remarkable is that all of these failure recovery procedures are transparent to the host system. The controller has been designed with ease of integration and maintenance in mind. [. . . ]
