    Cheetah 10K.6 FC Product Manual, Rev. F The buffer can be divided into logical segments (using Mode Select Page 08h, byte 13) from which data is read and to which data is written. The drive keeps track of the logical block addresses of the data stored in each segment of the buffer. If the cache is enabled (see RCD bit in the Fibre Channel Interface Manual ), data requested by the host with a read command is retrieved from the buffer, if possible, before any disc access is initiated.

  • Page 24: Reliability And Service

    Special equipment is required to repair the drive HDA. To achieve the above service life, repairs must be per- formed only at a properly equipped and staffed Seagate service and repair facility. Troubleshooting and repair of PCBs in the field is not recommended because of the extensive diagnostic equipment required for effective servicing.

  • Page 25: Hot Plugging The Drive

    Cheetah 10K.6 FC Product Manual, Rev. F 5.2.6 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 mecha- nisms, character sync, running disparity, word sync, and CRC are able to detect any error.
