具有内部互连的节点上的HA链路已关闭
适用场景
- AFF A220
- AFF A150
- FAS 27xx
- HA (高可用性)互连
问题描述
- HA互连通过中板进行、 事件日志会将链路报告 为已关闭:
Sat Oct 23 21:35:49 +0200 [node: gop_eq_thread: ic.linkStatusChange:info]: HA interconnect: Port ic0a link is down.
Sat Oct 23 21:35:49 +0200 [node: ctrl_hb_port_ic0a: ctrl.rdma.heartBeat:info]: HA interconnect: Missed heartbeat to 192.0.1.5.
Sat Oct 23 21:36:13 +0200 [node: cfdisk_config: cf.diskinventory.sendFailed:debug]: params: {'errorCode': '0', 'reason': 'HA Interconnect down'}
- 在某些情况下、可能还会看到HA链路发生闪烁。
- 已禁用集群HA:
Cluster::> cluster ha show
High-Availability Configured: false
High-Availability Backend Configured (MBX): -
Warning: Cluster HA has not been configured. Cluster HA must be configured
on a two-node cluster to ensure data access availability in the
event of storage failover. Use the "cluster ha modify -configured
true" command to configure cluster HA.
- 尝试配置HA失败、并显示以下错误:
Cluster::> cluster ha modify -configured true
Warning: High Availability (HA) configuration for cluster services requires
that both SFO storage failover and SFO auto-giveback be enabled. These
actions will be performed if necessary.
Do you want to continue? {y|n}: y
Error: command failed: Could not retrieve partner SFO information: entry
doesn't exist.
- 两个节点上的链路均报告为已关闭:
Cluster::*> system ha interconnect status show
Node: Node-01
Link Status: down
IC RDMA Connection: down
Node: Node-02
Link Status: down
IC RDMA Connection: down
