Single-Ended Scsi-2 Bus Configuration Constraints - HP C100/110 Owner's Manual

This workstation offers the following types of SCSI bus, each with its own
configuration constraints:

Single-Ended SCSI-2 Bus Configuration Constraints
For the single-ended standard SCSI-2 bus, HP-UX supports only one of each
type of removable disk drive and two of the same type tape devices per sys-
tem. Table 18 shows configuration constraints for each single-ended stan-
dard SCSI-2 device type. If the system has internal hard disk drives or a CD-
ROM drive, you must count them as SCSI-2 devices.
Table 18 Single-Ended SCSI-2 Bus Configuration Constraints
Single-Ended SCSI-2 Devices
Hard Disk Drives (external only)
CD-ROM Drives
4-mm DDS Tape Drives (one internal)
9-track Tape Drives
650-MB Magneto-Optical Drives
Magneto-Optical Autochangers (see notice below)
Maximum Number of SCSI-2 Devices
NOTICE: Magneto-Optical Autochangers use three SCSI-2 drive address. Each address
must be accounted for in the maximum number of SCSI-2 devices allowed.
CAUTION: Do not mix single-ended standard and fast, wide SCSI-2 peripherals.
Fast, Wide Differential SCSI Bus Configuration Constraints
Fast, wide SCSI does not work with the single-ended standard SCSI-2.
Table 19 shows the configuration constraints for each fast, wide, differential
SCSI device type.
