EMS 日志
在死机之前，您还可以在 ems 日志中看到以下内容：
cam: cam.timeout.retry:notice]: CAM device driver I/O timeout. Details: CAM command timeout (retrying), Device ada0 (4 retries left). Device ID: SPG2153013S. Command: WRITE_DMA. ACB: ca 00 bb 88 88 40 00 00 00 00 70 00.
启动失败期间的控制台启动消息
以下是在尝试 ONTAP 引导期间可能看到的控制台消息。
- 节点无法启动，控制台日志显示：
