问题

用户报告访问 FAS25xx 系列和集群模式 Data ONTAP 上集群模式 ONTAP 上托管的数据时协议延迟较长。

系统具有用于集群间端口的 QLogic NIC 卡。

AUPS 中可以报告类似于以下内容的 EMS 日志:
NwkThd_02: Nblade.dBladeNoResponse:warning]: Gave up retrying a file operation due to no response from the specified node. UUID of the node where data is located is fa000834-a355-11e4-87bc-5f5978ef59aa; the protocol for the operation is NFS.

可能还会报告类似以下内容的错误消息:
[Nblade.JunctionRootLookup2:warning] Junction root lookup of a volume in Vserver 5 with MSID 2147484692 has failed for reason "CSM_TIMEOUT"

[Nblade.CifsOperationTimedOut:error] Detected a timed out CIFS operation.
