问题描述

  • SinglePathToDiskShelf警报示例: 
::> system health alert show
Node: node_name
Resource: Shelf 1.1
Severity: Major
Indication Time: Wed May 11 21:14:22 2022
Suppress: false
Acknowledge: false
Probable Cause: Controller node_name has only a single-path configuration to disk shelf 1.1. This might occur
when the controller does not have dual-path configuration to stack 1, a SAS HBA port on the
controller connected to the disk shelf is disabled, or shelf-to-shelf cabling is incorrect.
Possible Effect: Access to disk shelf 1.1 via controller node_name might be lost with a failure of controller 0a port, a
single shelf-to-shelf cable or a single disk shelf IOM.
Corrective Actions: 1. Consult the guide applicable to your IOM12 disk shelf to review cabling rules and complete the SAS cabling worksheet for your system.
2. Connect controller node_name to the first and last disk shelf of stack 1 using active SAS HBA ports.
3. Verify that controller node_name is cabled to IOM A at one end and IOM B at another end of stack 1.
4. If disk shelf 1.1 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.
