- 报告NS224磁盘架路径丢失的事件消息：
[node_name-1: nchmd: hm.alert.raised:alert]: Alert Id = NoPathToNSMB_Alert , Alerting Resource = 012345678910111213 raised by monitor node-connect

或：
EventMessage = warning event on node_name-1 (Disk Shelf Multipath Not Configured)
ocumEventMessageDetails = Disk shelf has either one or no path connected to the node.
system health alert show输出：
Monitor node-connect
Alert ID NoPathToNSMA_Alert
Alerting Resource XXXXXXXXXXXXXXXXXXX
Subsystem SAS-connect
Indication Time Sun May 08 22:44:17 2022
Perceived Severity Major
Probable Cause Cable_tamper
Description Controller node_name-1 is connected only to module B of shelf 10.10 through port e3b.
Corrective Actions
1. Consult the guide applicable to your NVMe storage shelf to review cabling rules for your system.
2. Connect controller node_name-1 to module A and module B of shelf 10.10.
Possible Effect You will lose access to shelf 10.10 if module B fails.
system node run -node node_name-1 -command sysconfig -a输出、显示一个路径已关闭和一个"缺失"模块：
