Measures reported by NAUSDLunConfigTest

LUN conflicts may result in various issues such as data inconsistencies in the LUN as hosts may overwrite each others data or may lead to LUN reservation issues.

Conflicts may arise when a LUN is mapped to both the FCP and iSCSI initiator groups with the ALUA setting being enabled on atleast one of the initiator groups. Further mapping to the conflicted LUN will be possible only when the conflicts are resolved.

This test reports the count of LUNs that are victims of such a conflict. Using the detailed diagnosis of this test, you can identify the affected LUNs as well.

The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
Lun_conflict Indicates the number of LUNs that were mapped to both FCP and iSCSI initiator groups with the ALUA setting being enabled in both/atleast one of these initiator groups. Number A non-zero value is indicative of the existence of LUN conflicts. These conflicts can either be resolved by unmapping one or more mappings from the conflicting LUN or by disabling the ALUA setting on FCP or iSCSI or both the initiator groups whichever is applicable.

The detailed diagnosis capability of this measure if enabled, lists out the path of the LUNs with this ALUA setting conflict.
