1. Overview.

Disk Test for NetWare is a comprehensive tool for testing disk drives and NetWare partitions on Novell NetWare servers. Full support for execution on both NetWare and MS-DOS is supported. Support for MS-DOS is through our dsktest.exe module.

The following versions of Novell NetWare are supported:

  • Novell NetWare 3.12 and 3.20
  • Novell NetWare 4.11 and 4.20
  • Novell NetWare 5.0, 5.1 and Small Business Suite 5.1
  • Novell NetWare 6.0

The following versions of DOS are supported:

  • MSDOS 6.22
  • Novell DOS 7.03

This software runs as an NLM on a NetWare server. For NetWare 3.x and 4.x servers, both the NWIO (DSK) and NWPA (HAM) device driver interfaces are supported. For NetWare 5.x, only the NWPA (HAM) interface is supported.

Various verify methods are supported:

  1. Read-Only sequential verify. This method performs a read only sequential scan of the disk drive. Various block sizes are supported from 1 sector to 512 sectors per I/O. No data is written to the drive. This method is also a quick method to determine the read performance of a disk drive.
  2. Read-Only random verify. This method performs a read only random scan of the disk drive. The software generates a random number that is used to determine the sector to read. Various block sizes are supported from 1 sector to 512 sectors per I/O. No data is written to the drive. This method is also a quick method to determine the random I/O performance of a disk drive.
  3. Read-Write sequential verify. This method verifies that data can be written to a disk drive and then read back. A data pattern that is unique to each sector is written to the disk and then compared on read back. Various block sizes are supported from 1 sector to 512 sectors per I/O. For this verify mode an option is to perform an extensive verify which writes multiple data patterns to the disk drive. This includes performing a bit-walk data pattern to detect missing sector bits. Data is written to the drive, which will destroy all partitions, volumes and data on the disk drive.
  4. Read-Write random verify. This method verifies that the data can be written to a disk drive and then read back. The software generates a random number that is used to determine the sector to write / read. Various block sizes are supported from 1 sector to 512 sectors per I/O. For this verify mode an option is to perform an extensive verify which writes multiple data patterns to the disk drive. This includes performing a bit-walk data pattern to detect missing sector bits. Data is written to the drive, which will destroy all partitions, volumes and data on the disk drive.

2. Installation and Removal.

Installation for NetWare:

This software is packaged as a zip file. Create a temporary directory on your system and unzip the files. This software does not require an installation before use. However, there are three supported installation methods:

  1. Installation using INSTALL.NLM (NW 3 & 4) or NWCONFIG.NLM (NW 5 & 6). Copy the files either to a floppy diskette or to a temporary directory on your server. Using INSTALL.NLM or NWCONFIG.NLM select "Product Options". Then select "Install a product not listed".
  2. Create the directory SYS:/DSKTEST. Copy the files to the SYS:/DSKTEST directory on your server. The software can also be copied to any directory on your server.
  3. Installation using PINSTALL.NLM. From the server console type: "load a:pinstall.nlm" if the files are on a floppy diskette, or "load <path>/pinstall.nlm" if the files are on a directory on the server.

The default installation directory is SYS:/DSKTEST.

To execute the software type: "load sys:/dsktest/dsktest" at the server console.

See the command line options section below.

To remove the software, use INSTALL.NLM (NW 4) or NWCONFIG.NLM (NW 5). Select "Product Options". Then select "View/Configure/Remove install products". Then select DSKTEST and press delete.

Installation for MSDOS:

  1. This software is packaged as a zip file. Create a temporary directory on your system and unzip the files. This software does not require an installation before use.
  2. Copy the following files to a floppy:
    dsktest.exe
    dsktest.nlm
    dsktest.lic
  3. The DOS software supports IDE, EIDE and SCSI devices. For SCSI devices an ASPI device driver needs to be loaded.

To execute the software type: "dsktest" at the DOS prompt. The dsktest module will load, detect available disk drives, and then execute the module dsktest.nlm.

The module dsktest.exe behaves like a NetWare console. This module enables software written for NetWare servers to load under MS-DOS.

See the command line options section below.


3. What's New in Release 3.00?

New features:

  1. Added support for NetWare 6.

Bugs Fixed:

None.


4. Known Issues.

  • There are no known bugs in the software.

5. Command Line Options.

This version supports a number of command line options that can be used to modify the behavior of the software.

Command Syntax:

  • dsktest [options]

The following are valid command line options:

  • -help

Display the help screen. All other options will be ignored.

  • -logfile=filename

This option creates a file on either a NetWare volume or a file located on the DOS partition. This option allows for the status of a disk test to be logged. The output will overwrite the file.


6. Software Updates

Storage Manager supports updating itself over the Internet. The update feature will connect to our web server and retrieve a file that lists the latest files. No information about your server or software is sent to our web server. We use the HTTP "GET" command for all software downloads.

An error message will sometimes occur about not being able to resolve the address www.portlock.com. This is fixed by loading the Novell NLM netdb.nlm which provides the DNS name resolution that Disk Test needs. As a fallback we have hard coded the IP address of our web server into Disk Test.


7. Reporting problems to us.

Portlock Software is very interested in any comments regarding \Disk Test. Many features in the current product are the result of customers letting us know what they need.

When reporting a problem to us, use the command line option -logfile to help us identify the problem.

dsktest -logfile=filename
