SnapMirror传输失败、并出现校验和不匹配或未整理错误

适用场景

• ONTAP 9
• SnapMirror
• 网络连接

问题描述

• SnapMirror传输失败、并显示SnapMirror目标上的/etc/log/snapmirror_audit 日志中显示以下一个或多个校验和或完整性错误：
  • Fri Dec 01 10:00:00 EST 2015 ScheduledUpdate[Dec 01 09:30:00]:67890123-a123-a123-a123-123456789012 action=Defer source=sourceSVM:sourceVolume destination=destinationSVM:destinationVolume status=Failure message=Transfer failed.(Checksum mismatch(Replication engine error))

(CSM: Operation referred to a non-existent session.)Failed to get information for source volume "SVM1:Vol1" for setup of transfer. (CSM: Operation referred to a non-existent session.)

• SnapMirror也可能会失败、并显示以下一个或多个集群会话管理器(Cluster Session Manager、CSM)取消组织错误：
  • Fri Dec 01 10:00:00 EST 2015 ScheduledUpdate[Dec 01 09:30:00]:67890123-a123-a123-a123-123456789012 action=Defer source=sourceSVM:sourceVolumedestination=destinationSVM:destinationVolume status=Failure message=Failed to get information forsource volume "sourceSVM:sourceVolume" for setup of transfer.(Internal error: failed to unmarshal SnapMirror control operation data.)

• 在源集群EMS.log中、您可能会遇到以下错误：

Tue Aug 13 08:13:28 -0500 [FAS8200-Bot: kernel: netif.tcp.conn.bad.checksum:error]: TCP packet with bad checksum detected on port (IC Lif port). The packet arrived on connection with source address (IC Lif IP) and destination_address (IC Lif IP).
