Troubleshooting

EIDE Tape Drive

If the Store Controller is indicating an error during the boot process prior to the ªIBM 4690 OS 386 V1 ...º message, the problem is not in the 4690 software. The problem is either a hardware failure, a hardware con®guration problem, downlevel BIOS, or downlevel ®rmware in the tape drive. Check for the following conditions:

vMake sure the jumpers are correct. On each ribbon cable, there must be no more than one device jumpered as the ªmasterº or ªmaster with a slave attachedº. If there are two devices on the ribbon cable, one, and only one, must be jumpered as the slave.

vMake sure the ribbon cable is attached correctly to both the devices and the connector on the system board.

vMake sure the tape drive ®rmware is current. See ªUpgrading the Firmware for the Tape Driveº on page 11 to determine if you need to upgrade the ®rmware.

vMake sure the BIOS of the Store Controller is current. You can try upgrading the BIOS to a more recent level.

If the Streaming Tape Drive Utility abends with a W639 B4/S056/E001 message, it indicates that either the TAPESTRS 5 or TAPESTRM 5 command was not executed, the Store Controller does not support the tape drive, or that the Store Controller could not detect the tape drive.

Make sure that the following conditions exist:

vThe tape drive is on the secondary ribbon cable.

vTAPESTRM 5 was run from Command Mode and TAPESTRS 5 was run from the Supplemental Diskettes. After running the command, you must reboot your system.

vThe Store Controller is an ISA bus system (that is, a PC 300 through PC 750 series).

vThe Con®guration/Setup Utility accessed by pressing F1 when prompted during the boot process can detect the tape drive. The tape drive should show as a CD-ROM and Installed. If the Con®guration/Setup Utility cannot detect the tape drive, check the connections and jumpers.

vThe tape drive model is supported.
