问题描述
- EMS具有以下信息
Sat Mar 25 21:56:35 KST [node1: CsmMpAgentThread: csm.sessionFailed:error]: Cluster interconnect session (req=node1:dblade, rsp=node2:dblade, uniquifier=0e05f7a4ec72fb2f) failed with record state ACTIVE and error CSM_CONNABORTED.
Sat Mar 25 21:56:35 KST [node1: CsmMpAgentThread: csm.sessionFailed:error]: Cluster interconnect session (req=node1:dblade, rsp=node3:dblade, uniquifier=0e05f7a4ec71da20) failed with record state ACTIVE and error CSM_CONNABORTED.
- 上述uniqueifier的前两位数为0e、这是十六进制数、与表中的0x0E匹配。我们可以看到这是一个集群对等会话。
| 0x0E | CSM会话标记CPEER | 集群对等会话 |
- 可以在中看到正在销毁的空闲会话
