使用 BES-53248 的 MetroCluster IP 或集群出现 CRC 错误
状态信息
适用场景
- ONTAP 9
- MetroCluster IP 或集群
- BES — 53248
- EFOS 3.4.3.3
- EFOS 3.4.4.2
问题描述
- 报告了一个或多个集群端口上的 CRC 错误
- 可能会在 ONTAP 升级后发生，从而导致所有节点的性能低下
- EMS / 事件日志报告了以下内容：
[cshmd: hm.alert.raised:alert]: Alert Id = SwitchIfOutErrorsWarn_Alert , Alerting Resource = switch/Slot: 0 Port: 9 25G - Level raised by monitor cluster-switch
[intr: netif.linkErrors:error]: Excessive link errors on network interface e0a. Might indicate a bad cable, switch port, or NIC, or that a cable connector is not fully inserted in a socket. On a 10/100 port, might indicate a duplex mismatch.
[vifmgr: vifmgr.cluscheck.crcerrors:alert]: Port e0a on node is reporting a high number of observed hardware errors, possibly CRC errors.
- 在 MetroCluster IP 环境中，错误与未同步的日志错误同时发生：
[monitor: monitor.globalStatus.critical:EMERGENCY]: Controller failover of affnode is not possible: unsynchronized log.
[cf_main: cf.fsm.takeoverOfPartnerDisabled:error]: Failover monitor: takeover of affnode disabled (unsynchronized log).
[intr: netif.linkErrors:error]: Excessive link errors on network interface e0a. Might indicate a bad cable, switch port, or NIC, or that a cable connector is not fully inserted in a socket. On a 10/100 port, might indicate a duplex mismatch.
[vifmgr: vifmgr.cluscheck.crcerrors:alert]: Port e0a on node affnode is reporting a high number of observed hardware errors, possibly CRC errors.
- ifstat 输出中报告了较高的 CRC 错误：
...
Non-primary u/c: 0 | CRC errors: 175k | Runt frames: 0
...
- 在连接到集群端口的交换机端口上报告接口错误：
