Changing Your Workstation’s Hardware Configuration

Checking the SCSI IDs

After a few moments the ioscan utility lists all of the SCSI I/O devices it could find. The list appears similar to the following:

4If you are using HP-UX 9.05 or greater, you can find out the SCSI IDs currently in use by looking under the H/W Path heading. 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.

Although the information is presented in a different format if you are using HP- UX 10.0, you also look under the H/W Path heading.

NOTICE:Never use SCSI address 7 for any device. Address 7 is reserved for the SCSI controller.
