Troubleshooting
EIDE Tape Drive
If the Store Controller is indicating an error during the boot process prior to the
“IBM 4690 OS 386 V1 ...” message, the problem is not in the 4690 software. The
problem is either a hardware failure, a hardware configuration problem, downlevel
BIOS, or downlevel firmware in the tape drive. Check for the following conditions:
v Make sure the jumpers are correct. On each ribbon cable, there must be no more
than one device jumpered as the “master” or “master with a slave attached”. If
there are two devices on the ribbon cable, one, and only one, must be jumpered
as the slave.
v Make sure the ribbon cable is attached correctly to both the devices and the
connector on the system board.
v Make sure the tape drive firmware is current. See “Upgrading the Firmware for
the Tape Drive” on page 11 to determine if you need to upgrade the firmware.
v Make 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:
v The tape drive is on the secondary ribbon cable.
v TAPESTRM 5 was run from Command Mode and TAPESTRS 5 was run from
the Supplemental Diskettes. After running the command, you must reboot your
system.
v The Store Controller is an ISA bus system (that is, a PC 300 through PC 750
series).
v The Configuration/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 Configuration/Setup Utility cannot detect the tape
drive, check the connections and jumpers.
v The tape drive model is supported.
