问题描述

We see the following EMS message in logs. If the message repeats every few minutes, it might indicate a problem in the cluster interface configuration or the physical cabling of the switchless cluster. If two-node switchless A400 cluster ports are cross-cabled, remote data access might have intermittent issues due to session establishment failures. Additional issues on the cluster may arise due to the cross-cabled ports, and thus identifying and resolving the cross-cabled ports is the first step prior to resolving any other issues on your cluster. [cluster01-01: kernel: csm.homePortInfoUnexpected:notice]: CSM reports unexpected information for cluster LIF ID "1023" (home port: "e3b", remote device ID: "e3a"). Intermittent timedout alerts for NFS mounts on the servers. cluster02-02 ERROR Nblade.nfsConnResetAndClose: Shutting down connection with the client. Vserver ID is 4; network data protocol is NFS, Rpc Xid 0x0; client IP address:port is 10.120.10.19:25368. local IP address is 10.120.10.18; reason is Idle Timeout, closing connection.
