ALUA MPIO Test (LOGO)

Note  This content applies to the Windows Logo Kit (WLK). For the latest information using the new Windows Hardware Certification Kit (HCK), see Windows HCK User's Guide on the Windows Hardware Dev Center.

Type: Automated test

Overview

Asymmetric logical unit access (ALUA) occurs when the access characteristics of one port may differ from those of another port. Therefore, for storage devices with ALUA feature implemented, there may be at least two target port groups. This test verifies whether storage devices support the ALUA feature properly.

Note  This test depends on the SCSI Compliance Test 2.0 binary. Please make sure that LUN0 is the largest non-boot LUN before running the test.

Details

The test checks whether the device declares support to ALUA by checking the INQUIRY TPGS field before additional testing. If the TGPS field is not 0, then the storage devices at least support REPORT TARGET PORT GROUPS, and the Report Target Port Groups test will be done. If TPGS is 2 or 3, then the storage devices support both REPORT TARGET PORT GROUPS and explicit SET TARGET PORT GROUPS. In this case, the test will perform the Report Target Port Groups test and Set Target Port Groups test.
