4.
If you are using HP-UX 9.05, you can determine which SCSI
IDs are currently in use by looking under the H/W Path head-
ing. The listing 2.0.1 scsi is the built-in SCSI bus controller. For
devices connected to the built-in SCSI bus, such as disks, the
fourth number is the SCSI ID for that device. For example, the
listing 2.0.1.6.0 in the sample device list tells you that there is a
SCSI device (a disk) currently using ID 6 on the SCSI bus.
The information is presented in a different format if you are
using HP-UX 10.0 or later; although you still look under the
H/W Path heading.
NOTICE: Never use SCSI address 7 for any device. Ad-
dress 7 is reserved for the SCSI controller.
