14 Cheetah 36LP FC Product Manual, Rev. C 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 36LP FC disc drives by ensuring that the drive receives adequate cooling. Section 6.
Cheetah 36LP FC Product Manual, Rev. C 15 Failure rate is calculated as follows: • No system-induced failures counted • Based on 1,200,000 MTBF and 720 POH per month • Month 1’s rate includes a 300 PPM installation failure 5.2.3 Preventive maintenance No routine scheduled preventive maintenance is required. 5.2.4 Service life The drive has a useful service life of five years. Depot repair or replacement of major parts is permitted during the lifetime. 5.2.
16 Note. Cheetah 36LP FC Product Manual, Rev. C The drive’s firmware monitors specific attributes for degradation over time but can’t predict instantaneous drive failures. Each monitored attribute has been selected to monitor a specific set of failure conditions in the operating performance of the drive and the thresholds are optimized to minimize “false” and “failed” predictions.

There is a separate Failure History Counter for each attribute. 5.2.9 Drive Self Test (DST) Drive Self Test (DST) is a technology designed to recognize drive fault conditions that qualify the drive as a failed unit. DST validates the functionality of the drive at a system level. There are two test coverage options implemented in DST: 1.
18 5.2.9.2.3 Cheetah 36LP FC Product Manual, Rev. C Short and extended tests DST has two testing options: 1. short 2. extended These testing options are described in the following two subsections. Each test consists of three segments: an electrical test segment, a servo test segment, and a read/verify scan segment. Short test (Function Code: 001b) The purpose of the short test is to provide a time-limited test that tests as much of the drive as possible within 120 seconds.
Cheetah 36LP FC Product Manual, Rev. C 19 will pay for transporting the repair or replacement item to the customer. For more detailed warranty information, refer to the standard terms and conditions of purchase for Seagate products on your purchase documentation.

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.

If the drive is installed in an enclosure to which the stated shock and/or vibration criteria is applied, resonances may occur internally to the enclosure resulting in drive movement in excess of the stated limits. If this situation is apparent, it may be necessary to modify the enclosure to minimize drive movement.

Cheetah 36LP FC Product Manual, Rev. C 7.0 33 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).
34 Cheetah 36LP FC Product Manual, Rev. C 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 36LP FC Product Manual, Rev. C 8.0 35 Installation Cheetah 36LP 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 36LP FC Product Manual, Rev. C 8.4.1 37 Air flow The rack, cabinet, or drawer environment for the drive must provide heat removal from the electronics and head and disc assembly (HDA). You should confirm that adequate heat removal is provided using the temperature measurement guidelines described in Section 6.4.1.
38 Note. 8.6 Cheetah 36LP FC Product Manual, Rev. C Before mounting the drive in any kind of 3.5-inch to 5.25-inch adapter frame, verify with Seagate Technology that the drive can meet the shock and vibration specifications given herein while mounted in such an adapter frame. Adapter frames that are available may not have a mechanical structure capable of mounting the drive so that it can meet the shock and vibration specifications listed in this manual.

Changeable values Changeable values form a bit mask, stored in nonvolatile memory, that dictates which of the current values and saved values can be changed by a Mode Select command. A one (1) indicates the value can be changed. A zero (0) indicates the value is not changeable. For example, in Table 16, refer to Mode page 81, in the row entitled “CHG.” These are hex numbers representing the changeable values for Mode page 81.

Cheetah 36LP FC Product Manual, Rev. C 57 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.
58 9.5.11.1 Cheetah 36LP FC Product Manual, Rev. C 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 36LP FC Product Manual, Rev.
60 9.5.12 Cheetah 36LP FC Product Manual, Rev. C 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 24 lists the supported codes.
Cheetah 36LP FC Product Manual, Rev. C 9.6.3 61 Differential PECL output The serial PECL output signal voltage characteristics are provided in Table 27. 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.
