问题

由于多磁盘死机 (MDP) 导致的单节点重新启动：

[Node2: config_thread: cf.multidisk.fatalProblem:error]: Node encountered a multidisk error or other fatal error while waiting to be taken over.

节点正常重新启动，之后未出现磁盘问题。
EMS 显示存储端口同时关闭：

[Node2: mgmt_port_link_status_poll: netif.linkDown:info]: Ethernet e3a: Link down, check cable.
[Node2: mgmt_port_link_status_poll: netif.linkDown:info]: Ethernet e3a-30: Link down, check cable.
[Node2: mgmt_port_link_status_poll: netif.linkDown:info]: Ethernet e3b: Link down, check cable.
[Node2: mgmt_port_link_status_poll: netif.linkDown:info]: Ethernet e3b-30: Link down, check cable.

EMS 显示单个模块重启的消息：

[Node2: storlog_admin: sla.shelf.mod.reboot:notice]: Reboot event reported by module B in shelf: 0s.0.0, log: Wed Mar 18 02:08:50 2026 ( 0+00:08:26.577); 02000233; U?; HAL; hal; 04; +++ Application version 0140 launching +++

环境输出显示重启的节点具有指向同一模块的 2 条路径：
