list of initiator groups for which the ALUA (Asymmetric Logical Unit Access) settings do not match between local and partner filers. ALUA is a T10 standard that specifies the access characteristics (in terms of performance and supported SCSI commands) of a Logical Unit that can be accessed through more than one target port. ALUA is typically used by host multi-path software to recognize primary and secondary paths to a Logical Unit when more than one path are available to the Logical Unit. If the ALUA setting does not match between the local and partner filers, it would affect the host multi-path software's ability to distingush primary and secondary paths. This could lead to incorrect system behaviour.
List of initiators which are members of initiator groups with differing Volume Set Addressing (VSA) settings. An initiator can only be a member of initiator groups which have the same VSA setting across all the initiator groups it is a member of.

Re: What API would show affending WWPNs for path misconfigured?
Yep, went through all of those APIs before posting on a controller that currently lists offending WWPNs in the check_config CLI output and none of those APIs correlated to the output of the CLI command.
