  • node-01のサービスが停止しているため、node-01から強制的にテイクオーバーします。

::> set -privilege advanced
::*> storage failover takeover -option force -ofnode node-01 -skip-lif-migration-before-takeover true

  • テイクオーバー後、サービスがリカバリされ、node-01のステータスがWaiting for givebackになります。
  • node-02からギブバックを実行しますが、そのあとにスロットのステータスが正しく設定されていないと AllPathToOneEndOfStack_Alert が表示されます。

Node node-02
Monitor node-connect
Alert ID AllPathToOneEndOfStack_Alert
Alerting Resource 1
Subsystem SAS-connect
Indication Time Mon May 01 09:25:02 2023
Perceived Severity Major
Probable Cause Cable_tamper
Description Controller node-02 is connected to only one end of stack 1 through disk shelf 1.20.
Corrective Actions 1. Consult the guide applicable to your IOM6 disk shelf to review cabling rules and complete the SAS cabling worksheet for your system.
2. Connect controller node-02 to the first and last disk shelves of stack 1.
3. Verify that controller node-02 is cabled to IOM A and IOM B of stack 1.
4. Contact technical support if the alert persists.

Possible Effect A single disk shelf failure within stack 1 might cause controller node-02 to lose access to multiple shelves in the stack.
