Data Domain:qlogic 卡导致的网络配置设置无效错误

Summary: 传输超时触发了 QLogic 自动恢复机制,该机制将接口从配置的 MTU 9000 重置为默认 MTU 1500;如果问题再次出现,我们可以手动还原 MTU 或使用默认值配置接口。

Cause

此问题是由 TX 超时引起的。虽然存在针对 QLogic TX 超时的自动恢复机制,但恢复过程会将网络接口重置为其默认配置。
在这种情况下,Data Domain 已配置 MTU 9000,但在触发自动恢复时,接口设置已恢复为默认 MTU 值 1500。

Resolution

如果问题再次出现,我们可以手动将 MTU 重置为所需值。

net config ethXx mtu 1500 

Or 

net config ethXx mtu 9000


或者,我们可以让这些接口保留默认 MTU 1500 的配置,以避免在恢复过程中更改 MTU。
