Hello Jilei,

hostAdd("CSNS-Server3","192.168.206.153")
value = -1 = 0xffffffff
perror
S_hostLib_HOST_ALREADY_ENTERED

This simply shows that the host is already known. This is because
vxWorks automatically does hostAdd() with the "host name" and "host
inet" from the boot parameters. Thus this line is simply not needed.

nfsMount("CSNS-Server3","/develeopment/beamimp/sunjl/synApp53/iocDAQ/DAQ1","/develeopment/beamimp/sunjl/synApp53/iocDAQ/DAQ1")
value = -1 = 0xffffffff
perror
S_rpcLib_RPC_TIMEDOUT

This looks like there is no NFS server running on CSNS-Server3. It may
also be that the NFS server only serves NFS version 4  or NFS over TCP.
Both is not usable with vxWorks. You need to run a version 3 UDP server.
Since your server is on a different network, you should also check if
there is a firewall in between. It may be that such a firewall blocks
UDP packages.

What you can do:
- Check that NFS is running on CSNS-Server3.
- Check /etc/exports. Is your IOC allowed to mount?
- Can you mount the directory from somewhere else?
  * A pc in network 192.168.206.*?
  * A pc in network 192.168.201.*?
- Check the options used for the nfs server: --no-udp or
--no-nfs-version 3 would be bad.
- Run wireshark (or etherreal or tcpdump) on the server and look for
packages from bi-mvme5100-2

Without knowing more details about your server and network environment I
cannot say more.Please consult your network administrator or the system
administrator of CSNS-Server3.

And these wrong return value cause the "SAVE DATA" of the "scan.adl"  in "Mount err   Invalid file system!!!" state, right?
