A single shelf must be set to “First” shelf (see page 3-3). A single shelf may be either “Single Host” or “Dual Host” (see page 3-3). The VEM switch must be set to “Single VEM”. When Configuring Two Shelves on One SCSI Bus 1. 2. 3. 4. 5.
Cabling and Configuration Setting First/Second Shelf This switch enables a shelf to be set as the “First” or “Second” shelf. In Single shelf configurations this switch should always be set at First. In Dual shelf (daisychained) configurations, one shelf must be set as First and the second shelf must be set as Second. The switch is located at the rear of the shelf (see Figure 3-1). To set the shelf to First, the switch should be set to “First”.
Cabling and Configuration Setting Dual VEM Enable/Disable This switch enables Dual VEM to be Enabled or Disabled for a shelf. In a single shelf configuration the Dual VEM Enable/Disable switch must be set to Disabled. In a dual shelf (daisy-chained) configuration the Dual VEM Enable/Disable switch must be set to Enabled. The switch is located at the rear of the shelf (see Figure 3-3). To set shelf to Enabled the switch should be set to “2”. To set the shelf to Disabled the switch should be set to “0 or 1”.
Cabling and Configuration SCSI ID Selection This section describes the SCSI ID mappings used in the RAIDStation7 Ultra160 SCSI Storage Array. The SCSI ID mapping and the System Configuration ID mapping are detailed. SCSI ID Mapping The SCSI ID’s are set automatically via the combination of configuration switch settings. • The First/Second shelf switch can be “F” or “S”, (First or Second). • The Single/Dual host switch can be “S” or “D”, (Single or Dual).
Cabling and Configuration System Configuration ID Mapping The following table sets out the ID mapping for the various configurations. For the purpose of this table each configuration will be represented by the number given to it on the first page of this chapter. The First Shelf is represented by “1st” and the Second Shelf is represented by “2nd”.
Cabling and Configuration Connecting to a Host System This section describes the procedure for connecting the RAIDStation7 Ultra160 SCSI Storage Array to a single or dual host. NOTE: This section describes the connectors on the RAIDStation7 Ultra160 SCSI Storage Array, it does not describe the connectors on the host. For information relating to the host, refer to the host systems User Guide.
Cabling and Configuration Dual Shelf, Single Host In this configuration two RAIDStation7 Ultra160 SCSI Storage Array shelves are daisy chained together and connected to a single host system. The SCSI cable is connected to the top I/O connector (when Storage Array is vertically oriented) of Shelf 1, the other end of this cable is connected to the host system. The bottom I/ O connector of Shelf 1 is connected to the top I/O connector of Shelf 2 (see Figure 3-5).
Cabling and Configuration Dual Host Configurations Both the single shelf and dual shelf configurations described may be connected to dual host systems. This is achieved by daisy-chaining the host computers together. When connecting either a single or dual shelf configuration to dual hosts, ensure that the Single/Dual Host ID switch is set to Dual (on both shelves for dual shelf configurations). NOTE: It is also possible to have two SCSI adapter cards in a single host computer.

Ensure the power switch on the disk shelf is in the off position.
Environmental Monitoring Chapter 4: Environmental Monitoring This Chapter deals with the various methods used to monitor the RAIDStation7 Ultra160 SCSI Storage Array. There are two methods used: • Versatile Environmental Monitor (VEM) - The VEM is a card that plugs into the backplane of the Storage Array. The VEM monitors the ACMs, power supply voltage outputs and enclosure temperature. • Device Carrier LEDs - All device carriers have two LEDs on the front which are driven by the VEM.
Environmental Monitoring Versatile Environmental Monitor (VEM) The VEM is a Storage Array environmental monitoring device. It sits on the backplane of the RAIDStation7 Ultra160 SCSI Storage Array. It gathers information about the state of the devices in the Storage Array, such as power supplies, disk drives, Advanced Cooling Modules and enclosure temperature. It communicates with the host system using in-band reporting.
Environmental Monitoring In-Band Reporting The VEM communicates with the host system using in-band reporting and supports both SAF-TE and SES protocols. The VEM card sits on the SCSI bus and communicates directly to the host(s). The VEM card has it’s own SCSI ID (see below) and is seen as a separate target by the host(s). VEM SCSI ID The VEM sits on the SCSI bus and as such it is assigned a SCSI ID.
Environmental Monitoring Advanced Cooling Module Failure LED Each ACM has a fault LED built into it (see Figure 4-2). If an ACM fails, its ACM Failure LED will turn on, and the alarm buzzer on the VEM card will sound. The alarm buzzer may be silenced by pressing the alarm silence button. Figure 4-2.
Environmental Monitoring Disk Drive Carrier LEDs Each disk drive carrier in a disk shelf has two LED indicators on the front (see Figure 4-3). These LED indicators are driven by the VEM. Figure 4-3. LEDs On Disk Drive Carrier Device Fault LED (RED) Device Activity LED (GREEN) The disk drive LEDs function as follows: • The Green LED on the top is the device activity indicator. It is on or flashing when the disk is active. • The Red LED on the bottom is the device fault indicator.
