3.1.4.2 Determining SCSI Address IDs for Drives In the System
If you do not know which device is installed at what SCSI address ID or
whether the device is on the SCSI-A or SCSI-B bus, enter SHOW DEVICE
at the console prompt >>>. The SHOW DEVICE command displays all
devices connected to the MSC module's bus controllers. This display lists the
SCSI address ID of
all devices on SCSI buses. Figure
3-6 shows an example
of this command.
