SCSI Configuration Constraints

You are limited to the number of same-type SCSI devices per system. Before adding another SCSI device, determine if the system can support the addi- tional device.

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

• Narrow, Single-ended SCSI bus (C160/C180/C200/C240)

• Fast, Wide Differential SCSI bus (C160/C180/C200 upgrade)

• Ultra, Wide-Single-Ended SCSI bus (C200/C240 only)

Narrow, Single-ended SCSI Bus Configuration Constraints

For the NSE SCSI bus, HP-UX supports only one of each type of removable disk drive and two of the same type tape devices per system. Table 21 shows conﬁguration constraints for each NSE SCSI device type. If the system has an internal CD-ROM drive or DDS tape drive, you must count them as NSE SCSI devices.

Table 21		NSE SCSI Bus Conﬁguration Constraints

		NSE SCSI Devices	Maximum Number of Each
		NSE SCSI Devices	Type of Device Allowed
			Type of Device Allowed

		Hard Disk Drives (external only)	7

		CD-ROM Drives (one internal)	1

		4-mm DDS Tape Drives (one internal)	2

		9-track Tape Drives	2

		650-MB Magneto-Optical Drives	1

		Magneto-Optical Autochangers (see notice below)	1

		Maximum Number of NSE SCSI Devices	7

		NOTICE: Magneto-Optical Autochangers use three NSE SCSI drive address. Each ad-
		dress must be accounted for in the maximum number of NSE SCSI devices al-
		lowed.
