The syntax for RAIDmark is as follows:
raidmark [-d<drive>] [-s<size>] [-t<duration>] [-l<filename>]
[-u<filename>] [-r<filename>] [-v] [-m] [-c<comment>]
[-f<N>]
or
raidmark {-? | -h}
All parameters are optional.
Command-line arguments are as follows:
-d<drive>
Tested drive ID. This is the name of the drive to be tested.
In DOS, a letter, such as 'C':
-dC
In NOVELL, the volume name, such as 'sys':
-dSYS
The default is the current drive.
-s<size>
Test file size in megabytes. If left out, this will default
to half the available disk space, with a maximum of 128
megabytes. Typically, this file should be at least 5 times
bigger than the disk cache. The bigger the test file, the
more accurate results you will get.
-s64
will create a 64 megabyte test file.
-t<duration>
Duration of the whole test in minutes. Actually, this number
is the total for raw access and application level test. Time
spent doing user defined tests is not included in this
number. Because of cache overflow routines, the test may
take more time than specified to complete, as this number is
an approximation of the effective time spent doing actual
testing.
-t5
will run RAIDmark to give you 5 minutes effective time.
The default is 15 minutes.
-l<filename>
Log file name. Specify full pathname if you want to place
the log file outside the current directory.
For DOS:
-lc:\temp\logs\raidmark.log
For NOVELL:
-lsys:temp\logs\raidmark.log
Default action is to prompt the user for a filename.
-u<filename>
User defined test file. Specify full pathname as with log
files. You can simulate different environments by changing
this file with any ASCII editor. If this parameter is
omitted, RAIDmark will look for the file TESTCASE.RDM in the
current directory. If it does not find it, RAIDmark will ask
you if you want to run user-defined tests. The format for
the user-defined test file is illustrated in the example
file TESTCASE.RDM included with this package.
-r<filename>
Report file name. Supply a file name into which test results
will be saved for processing by the stand-alone comparison
utility. The default extension is '.DAT'.
-v
Verify record checksum flag. If you supply this flag, every
record read from the test file will be checked for errors.
This will, of course, somewhat slow down the testing.
Default is no verification.
-m
Monochrome display. Supply this parameter if you are running
RAIDmark on a system with a monochrome monitor. Default is
16-color text mode.
-c<comment>
Comment to be inserted into the log file. This can be any
alpha-numeric string without spaces. Use underscores where
you would normally put spaces, e.g.
-cExample_of_comment
-f<N>
Force the cache file size to be at least N megabytes long.
-f10
will make RAIDmark think that the disk cache is at least 10
megabytes. This rarely-used option should be activated to
ensure valid results whenever RAIDmark cannot correctly
determine the actual cache size.
-? or -h
Quick help screen.
To eliminate caching problems, the test file should be as large as
possible. Make sure you have sufficient space on the tested drive.
Typically, you will need the size you specified as test file size plus
the cache size. In addition, the system on which you are running
RAIDmark might need some extra disk space as well.
On a multi-processing system, RAIDmark should be the only running
process, in order to get accurate results.
When using the Novell version of RAIDmark, make sure 'MATHLIB.NLM' has
been loaded prior to running RAIDMARK.NLM.
When viewing the summary screens, you have 30 seconds before the
screen changes. To force a pause, press P when the screen is
displayed. Then, any key will continue. You also have the option to
save the test data into a file for later processing by the stand-alone
comparison program. To activate this option, press S while the summary
screen are displayed. RAIDmark will prompt you for a filename under
which the test data will be saved. The default file extension is
'.DAT'.
The 'escape' key will abort the current test at any stage.
Revision history:
1.1 November 11, 1992
Fixed problem reading 'TESTCASE.RDM' user-defined tests
file. Format for MS-DOS is now identical to the Novell
format.
Added the file 'PATCH311.NLM' from Novell, Inc., to
distribution diskette to fix erroneous free disk space
report in Novell.
Minor enhancements.
1.0 October 7, 1992
Initial release.
