CONTAP-307287: False SinglePathToDiskShelf_Alert for shelf stack

Issue

False ONTAP health alert generated for disk shelf with stack ID that no longer exists. The shelf itself is visible and healthy but on a different stack.
Node: Node-01
Alert ID: SinglePathToDiskShelf_alert
Resource: Shelf 2.1
Severity: Major
Indication Time: Thu Oct 19 15:17:54 2023
Suppress: true
Acknowledge: true
Probable Cause: Controller Node-01 has only a single-path configuration to disk shelf 2.1. This might occur when teh controller does not have a dual-path configuration to stack 2, a SAS HBA porton the controller connected to the disk shelf is disabled, or shelf-to-shelf cabling is incorrect.
Possible Effect: Access to disk shelf 2.1 via controller Node-01 might be lost with a failure of controller 0d port, a single shelf-to-shelf cable or a single disk shelf IOM.
Corrective Actions:
1. Consult the guide applicable to your IOM12B disk shelf to review cabling rules and complete the SAS cabling worksheet for your system.
2. Connect controller Node-01 to the first and last disk shelf of stack 2 using active SAS HBA ports
3. Verify that controller Node-01 is cabled to IOM A at one end and IOM B at another end of stack 2.
4. If Disk shelf 2.1 is located between two disk shelves within stack 2, verify that IOM A and IOM B are properly cabled to their independent domains.
5. Contact technical support if the alert persists
