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.
