What API would show affending WWPNs for path misconfigured?

pclayton99 — Thu, 05 Jun 2025 06:12:21 GMT

Hello..

I have been poking around the APIs with ZExplorer looking for what is at the end of a 'lun config_check -A' command. Namely:

The following FCP Initiators are sending Read/Write i/o over the

FCP Partner Paths during the last 303 seconds

WWPN Partner's Port ops bytes ostype

21:00:00:24:ff:27:dc:80 0c 210296 1720878592 vmware

20:01:e0:db:55:79:e6:69 0c 3677 23773696 vmware

20:01:e0:db:55:79:e6:83 0c 7469 65996288 vmware

21:00:00:24:ff:27:d6:d2 0c 93084 1000456704 vmware

There are a number of other APIs that deal with options for config_check but those do not address the above aspect.

Is there a single or combo of APIs that would get this info?

Appreciate your time.

Have you tried

lun-config-check-info

]

Returns a list of lun/fcp configuration warnings. These warnings are not related to filer cluster configuration.

Output Name Range Type Description
alua-setting-mismatch-info
alua-setting-mismatch-initiator-group[]
optional
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.
alua-setting-mismatch-initiators
alua-setting-mismatch-initiator-info[]
optional
List of initiators which are members of initiator groups of differing alua settings.
fcp-down-hbas
fcp-down-hba-info[]
optional
list of HBA names that have no link or are configured down.
invalid-vsa-settings
invalid-vsa-setting-info[]
optional
List of initiator groups with invalid Volume Set Addressing (VSA) settings
mixed-ostype-initiators
mixed-ostype-initiator-info[]
optional
List of initiators which are members of initiator groups of differing ostypes.
mixed-vsa-initiators
mixed-vsa-initiator-info[]
optional
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.

Rick..

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.

Thanks.
