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:
• Single-ended SCSI bus
• Fast, Wide SCSI bus
Single-ended SCSI Bus Configuration Constraints
For the SE 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 22 shows
configuration constraints for each SE SCSI device type. If the system has an
internal CD-ROM drive or DDS tape drive, you must count them as SE
SCSI devices.
