This chapter explains what to do if you experience problems during the configuration
process. It also explains how to run the Support Tool Manager or the Extended Self Test
to verify your system.
If you are experiencing difficulty booting the system, reconfiguring HP–UX, or using the
CD–ROM drive, complete each of the following tasks, in the order they are presented,
until you discover and correct the problem:
•
Check the address settings of any single–ended SCSI–2 devices.
•
Check that you have installed the hardware correctly.
•
Recheck the device list.
•
Run verification tests.
Check the Address Settings for Single–Ended Drives
Check the address settings of each single–ended SCSI–2 device on the bus. Make sure
that no device has the same address setting of another.
If you find two devices with the
same address, change one of the devices to a different, unused address setting.
To check
the address settings for each single–ended SCSI–2 device, type the following in a
terminal window or HP–UX command line:
If you are using HP–UX 9.0x, enter the following at the prompt:
/etc/ioscan
