14 Cheetah 73LP FC Product Manual, Rev. D Sense Key. This is an unrecoverable seek error. Unrecoverable seek errors are classified as failures for MTBF calculations. Refer to the Fibre Channel Interface Manual, part number 77767496, for Request Sense information. 5.2 Reliability and service You can enhance the reliability of Cheetah 73LP FC disc drives by ensuring that the drive receives adequate cooling. Section 6.
Cheetah 73LP FC Product Manual, Rev. D 5.2.6 15 Hot plugging the drive Inserting and removing the drive on the FC-AL will interrupt loop operation. The interruption occurs when the receiver of the next device in the loop must synchronize to a different input signal. FC error detection mechanisms, character sync, running disparity, word sync, and CRC are able to detect any error. Recovery is initiated based on the type of error.

Recovered errors will not be reported as diagnostic failures. 5.2.8.2 Implementation This section provides all of the information necessary to implement the DST function on this drive. 5.2.8.2.
18 5.2.8.2.4 Cheetah 73LP FC Product Manual, Rev. D Log page entries When the drive begins DST, it creates a new entry in the Self-test Results Log page. The new entry is created by inserting a new self-test parameter block at the beginning of the self-test results log parameter section of the log page. Existing data will be moved to make room for the new parameter block. The drive reports 20 parameter blocks in the log page.

Cheetah 73LP FC Product Manual, Rev. D 6.3 23 Power dissipation ST373405FC Typical power dissipation under idle conditions is 11.3 watts (38.6 BTUs per hour). To obtain operating power for typical random read operations, refer to the following I/O rate curve (see Figure 7). Locate the typical I/O rate for a drive in your system on the horizontal axis and read the corresponding +5 volt current, +12 volt current, and total watts on the vertical axis. To calculate BTUs per hour, multiply watts by 3.4123. 1.

Cheetah 73LP FC Product Manual, Rev. D 7.0 29 Defect and error management The drive, as delivered, complies with this product manual. The read error rates and specified storage capacities are not dependent upon use of defect management routines by the host (initiator). Defect and error management in the SCSI protocol involves the drive internal defect/error management and FC-AL system error considerations (errors in communications between the initiator and the drive).
30 Cheetah 73LP FC Product Manual, Rev. D When the RC bit is one, reallocations are disabled even if the ARRE or AWRE bits are one. The drive will still perform data recovery actions within the limits defined by the Read Retry Count, Write Retry Count, and Recovery Time Limit parameters. However, the drive does not report any unrecovered errors.
Cheetah 73LP FC Product Manual, Rev. D 8.0 31 Installation Cheetah 73LP FC disc drive installation is a plug-and-play process. There are no jumpers, switches, or terminators on the drive. Simply plug the drive into the host’s 40-pin Fibre Channel backpanel connector (FCSCA)—no cables are required. See Section 9.5 for additional information about this connector. Use the FC-AL interface to select drive ID and all option configurations for devices on the loop.

Cheetah 73LP FC Product Manual, Rev. D 9.5.5 53 FC-AL transmitters and receivers A typical FC-AL differential copper transmitter and receiver pair is shown in Figure 19. The receiver is required to provide the AC coupling to eliminate ground shift noise. Figure 19. 9.5.6 FC-AL transmitters and receivers Power Power is supplied through the FC-SCA with support for +5 volts and +12 volts. All of the voltage pins in the drive connector are the same length.
54 Cheetah 73LP FC Product Manual, Rev. D The Active LED Out signal is designed to pull down the cathode of an LED. The anode is attached to the proper +5 volt supply through an appropriate current limiting resistor. The LED and the current limiting resistor are external to the drive. 9.5.9 Enable port bypass signals The – Enable Bypass Port A (– EN BYP Port A) and – Enable Bypass Port B (– EN BYP Port B) signals control the port bypass circuits (PBC) located external to the disc drive.
Cheetah 73LP FC Product Manual, Rev. D 9.5.11.1 55 Parallel Enclosure Services Interface (ESI) The parallel ESI line is an output from the drive. This line provides the enclosure with an indication of the present function of the SEL lines. A high level, the default state, indicates the drive requires address information on the SEL lines. A low level indicates the drive is attempting an ESI transfer. The enclosure may not support ESI on any or all drive locations. It may only support the address function.

Cheetah 73LP FC Product Manual, Rev. D 9.5.12 57 Device control codes The drive inputs a Device Control Code on the DEV_CTRL_CODE lines at power up to determine the link rate on the Fibre Channel ports. Both ports run at the same rate. If the backpanel does not connect to these lines, the drive has 10K ohm pull up resistors that default the device control code to 7 (1.0625 GHz). Table 23 lists the supported codes.
58 9.6.3 Cheetah 73LP FC Product Manual, Rev. D Differential PECL output The serial PECL output signal voltage characteristics are provided in Table 26. The outputs are not AC coupled in order to deliver maximum signal without rise and fall time degradation. You must AC couple the receiver to isolate potentially different DC characteristics of the outputs and the receiver.
