Physical disks
This subsection displays a list of hot physical disks. The maximum amount of physical disks displayed is the number of hot physical disks being monitored as specified with the -d flag. A smaller number of physical disks
will be displayed if other subsections are also being displayed. Pressing the d key turns off this subsection. Pressing the d key again shows a one-line report summary of the activity for all physical disks.

drtest

DRTEST(8)						      System Manager's Manual							 DRTEST(8)

NAME

       drtest - standalone disk test program

DESCRIPTION

       Drtest is a standalone program used to read a disk track by track.  It was primarily intended as a test program for new standalone drivers,
       but has shown useful in other contexts as well, such as verifying disks and running speed tests. For example, when a disk has been  format-
       ted  (by  format(8)), you can check that hard errors has been taken care of by running drtest.  No hard errors should be found, but in many
       cases quite a few soft ECC errors will be reported.

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

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.

	    >>>B/3
	    %%
	    loading hk(0,0)boot
	    Boot
	    : hk(0,0)drtest
	    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.
