SF72 Storage Enclosure Operation 3–11 The four 7-segment LED displays on the front of the OCP display these DSSI ID numbers. If a display is not lit, then that disk ISE position in the enclosure is not occupied by an RF72 disk ISE. The three disk ISE controls and indicators are to the right or left side of the 7-segment LED displays. These controls, with their associated indicators, are as follows (Figure 3–7): • Ready—The Ready button is a push-to-set switch with a green indicator.

3–14 SF72 Storage Enclosure Operation WARNING Hazardous voltages are present inside the equipment cabinet and the SF72 enclosure. Installation and service must be performed only by qualified Digital Customer Services engineers. When performing any operation involving the source power, verify that the enclosure ac power switch, located on the power supply at the rear of the enclosure, is turned off. Disconnect the line cord from the enclosure rear panel and from the cabinet power controller, if possible.
SF72 Storage Enclosure Operation 3–15 3.4 Applying Power to the Enclosure This section describes the correct procedure for powering up an SF72 storage enclosure. Perform all steps in the order in which they are presented. NOTE Do not change the DSSI ID setting while the power is on. Apply power to the enclosure as follows: 1. Verify that the drive dc power switches and all disk ISE control buttons on the front of the enclosure are in the off (0) position. 2.
3–16 SF72 Storage Enclosure Operation 3.5 Placing a Disk ISE On-Line After power is applied to the SF72 enclosure, use the following procedure to place a disk ISE on-line. Perform all steps in the order in which they are presented. 1. Press the Ready button on the OCP to bring the ISE on-line. a. The Ready indicator flickers while the disk ISE is spinning up.
4 Troubleshooting This chapter contains procedures a user can perform, before calling Digital Customer Services, to verify that a problem exists in the SF72 storage enclosure. Procedures to attempt recovery from a fault condition are also included here. Before attempting recovery from a fault condition, record the fault code shown on the SF72 storage enclosure operator control panel (OCP), as described in Section 4.2. 4.

4–4 Troubleshooting e. Verify that the line voltage selector switch on the rear panel of the power supply is set to the correct line voltage. Refer to Figure 4–1 for the location of the line voltage selector switch. f. Attempt to restart the enclosure. 2. If the drive dc power switches on the front panel of the enclosure are blinking, an overload at the output of the power supply is the likely cause. a. Place all OCP buttons for each disk ISE in the out (off) position. Refer to Figure 4–2. b.
Troubleshooting 4–5 4.2 Recovering from a Disk ISE Fault Condition The RF72 disk ISE contains sophisticated circuits to detect and report fault conditions. These faults are reported through a fault code display on the SF72 storage enclosure OCP. The Digital Customer Services engineer uses these codes and other error reporting mechanisms in the disk ISE to pinpoint the source of a fault and return your RF72 to service in the least amount of time.
Glossary ADAPTER A module that connects one or more device controllers to the host bus and hides many of the host bus requirements from the controller. The KFMSA module is an XMI to DSSI bus adapter. ALLOCATION CLASS A numerical value assigned to the ISE to indicate which host(s) on a cluster it will be served by. BAD BLOCK An address on a disk or tape that is determined by the device controller to be bad and, therefore, in need of replacement.
Glossary–2 DSSI Digital Storage System Interconnect. A DSA-based storage interconnect used by the KFMSA adapter and the RF- and TF-series integrated storage elements to transfer data and to communicate with each other. DUAL-HOST Storage configuration where DSSI ISEs are shared between two DSSI adapters and host systems. DUP Diagnostic and utility protocol. A SYSAP-level protocol by which a host computer directs a storage device controller to run internal diagnostics or utility functions.
Glossary–3 NODE NAME A 6-character (maximum) value that is assigned to each DSSI ISE. The node name of each ISE must be unique across the system topology. OCP Operator control panel. An enclosure interface that allows remote control of DSSI node ID selection and ISE operating status. PARAMS A local program resident on the ISE. PARAMS is used to view and modify current device parameter settings on an ISE. PATH A channel from the host to a device. RBN Replacement block number.
Glossary–4 THROUGH-BUS A mode of operation where all the ISEs in an SF72 enclosure are connected to the same DSSI bus. In this mode, the DSSI bus is terminated using an external terminator.
