Exabyte 230D Library Installation And Operation Manual page 244

Appendix B
Although LVD SCSI is compatible with single-ended SCSI, the
internal SCSI cable lengths for the 230D library (see
cause the total cable length to exceed the maximum length for a
single-ended bus. Exabyte therefore does not support
single-ended devices on the LVD SCSI bus for the 230D library.
The Exabyte 230D supports narrow or wide SCSI. The DLT 4000
tape drive supports narrow SCSI only; the DLT 7000 and DLT 8000
tape drives support wide SCSI only.
The library supports fast SCSI, which does not require any special
cabling or configuration. However, proper cable lengths, stub
length, and termination are more important on a fast SCSI bus
than on a regular SCSI bus.

Do not connect the LVD library to a single-ended
bus. Doing so may cause the bus to hang.
Also, do not mix LVD and HVD devices on the
same SCSI bus, or you may damage the devices
attached to that bus.
