Introduction

Single-Ended SCSI-2 Bus Configuration Constraints

For the single-ended SCSI-2 bus, HP-UX supports only one of each type of removable- media disk drive (i.e., floppy disk, CD-ROM, or magneto-optical drives) and two of the same type tape devices (i.e., 4-mm DDS tape drives or 9-track tape drives), per SCSI bus. You may connect no more than seven SCSI-2 devices to each single-ended SCSI-2 bus.

Table 1±1 shows the configuration constraints for each single-ended SCSI-2 device type. You may connect no more than seven SCSI-2 device IDs to each single-ended SCSI-2 bus. Some SCSI-2 devices use more than one SCSI-2 drive address. Each address must be accounted for in the maximum number of SCSI-2 devices allowed.

CAUTION: Do not connect single-ended SCSI-2 devices to a differential SCSI-2 bus or differential SCSI-2 devices to a single-ended SCSI-2 bus. Connecting a SCSI-2 device to the wrong SCSI-2 bus can cause system failure.
