Offload scenario test (LOGO)

  • Article

This test verifies behavior of offload capable devices when offload related commands are exercised. The test exercises Offload Reads and Offload Writes between LUNs of the same target (such as an adapter) and between LUNs of different adapters.

Additional documentation

Tests in this feature area might have additional documentation, including prerequisites, setup, and troubleshooting information, that can be found in the following topic(s):

Running the test

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

Attach the following to the HLK test machine: Storage adapter 1, LUNs 1 and 2 & Storage Adapter 2, LUN 3. LUNs 1, 2 and 3 should be a minimum of 21 GB in size.

Format and mount file system on LUNs 1, 2 and 3. When you schedule the test on the HLK controller, there is a run time parameter called "RemoteShareODXStorageDriveLetter". Provide the drive letter associated with LUN3 for the run-time parameter. For example, if LUNs 1, 2 and 3 have drive Letters X, Y and Z, type Z for the run-time parameter and schedule test.

When running the offload scenario test in conjunction with other storage tests, the drive configuration must be maintained for the tests in the same project.

Troubleshooting

For generic troubleshooting of HLK test failures, see Troubleshooting Windows HLK Test Failures.

For troubleshooting information, see Troubleshooting Device.Storage Testing.
