SCSI Reliability Counters Test (LOGO)

Storage Spaces has three certification programs: one for drives, one for enclosures, and one for host bus adapters. The reliability counter requirements apply to drives. These reliability counter requirements are a result of OEM feedback that they are necessary to enable troubleshooting issues in the field, and a result of the product team supporting and troubleshooting deployments.

This test checks if drives return reliability data log pages.

Test details

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):

• Device.Storage additional documentation

Running the test

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

If you are testing any drive that requires media or testing in system-mode on a computer that contains drives that require media, you must insert media into the drives. The media that is used must be formatted and contain data that occupies at least 50% of the media's capacity.

Troubleshooting

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

For troubleshooting information, see Troubleshooting Device.Storage Testing.
