DRTEST(8S)

NAME
drtest - standalone disk test program

SYNOPSIS
From the powerup monitor:

on SCED-based systems:
* b 0 dv(un,su) stand/drtest

on SSM-based systems:
---> bh dv(un,su) stand/drtest

DESCRIPTION
Drtest invokes a simple diagnostic test to read all accessible data from the specified device.

While drtest is running, the cylinder number is printed on the console for every 10th cylinder read.

Drtest prompts for needed information. Device names are specified in standalone file notation (see boot(8S)). Messages are intended to be self-explanatory.

EXAMPLE
A sample run of drtest is shown below. In this example (using a 750), drtest is loaded from the root file system; usually it will be loaded from the machine's console storage device. Boldface means user input. As usual, ``#'' and ``@'' may be used to edit input.

Test program for stand-alone up and hp driver

Debugging level (1=bse, 2=ecc, 3=bse+ecc)?
Enter disk name [type(adapter,unit), e.g. hp(1,3)]? hp(0,0)
Device data: #cylinders=1024, #tracks=16, #sectors=32
Testing hp(0,0), chunk size is 16384 bytes.
(chunk size is the number of bytes read per disk access)
Start ...Make sure hp(0,0) is online
 ...
(errors are reported as they occur)
 ...
(...program restarts to allow checking other disks)
(...to abort halt machine with ^P)

DIAGNOSTICS
The diagnostics are intended to be self explanatory. Note, however, that the device number in the diagnostic messages is identified as typeX (instead of type(a,u)), where X = a*8+u, e.g., hp(1,3) becomes hp11.
