Running the test

Before you run the test, complete the test setup as described in the test requirements: Hard Disk Drive Testing Prerequisites.

Troubleshooting

For troubleshooting information, see Troubleshooting Device.Storage Testing.

The test writes the results to the log files Scsicompliance.wtl and Scsicompliance.wtl.txt. You can use the results to determine:

  • If a device is compliant with the SCSI specification

  • The optional SCSI commands that are supported by a device

To pass, the SCSI device must support every mandatory command and must be fully compliant with those commands. Each command has a different threshold for pass or fail, and the expectations are specified explicitly in the test and in the log file.

Optional commands are also tested. If a device supports the optional commands and the commands are found to be non-compliant, the test fails. If the device does not support optional commands, the test passes.

More information
