8.0Installation

Cheetah 10K.7 FC disc drive installation is a plug-and-play process. There are no jumpers, switches, or termi- nators on the drive. Simply plug the drive into the host’s 40-pin Fibre Channel backpanel connector (FC- SCA)— 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.

If multiple devices are on the same FC-AL and physical addresses are used, set the device selection IDs (SEL IDs) on the backpanel so that no two devices have the same selection ID. This is called the hard assigned arbi- trated loop physical address (AL_PA). There are 125 AL_PAs available (see Table 31). If you set the AL_PA on the backpanel to any value other than 0, the device plugged into the backpanel’s SCA connector inherits this AL_PA. In the event you don’t successfully assign unique hard addresses (and therefore have duplicate selec- tion IDs assigned to two or more devices), the FC-AL generates a message indicating this condition. If you set the AL_PA on the backpanel to a value of 0, the system issues a unique soft-assigned physical address auto- matically.

Loop initialization is the process used to verify or obtain an address. The loop initialization process is per- formed when power is applied to the drive, when a device is added or removed from the Fibre Channel loop, or when a device times out attempting to win arbitration.

•Set all option selections in the connector prior to applying power to the drive. If you change options after applying power to the drive, recycle the drive power to activate the new settings.

•It is not necessary to low-level format this drive. The drive is shipped from the factory low-level formatted in 512-byte logical blocks. You need to reformat the drive only if you want to select a different logical block size.

8.1Drive ID/option selection

All drive options are made through the interface connector (J1). Table provides the pin descriptions for the 40- pin Fibre Channel single connector (J1).
