Hi,
Were implementing a new cluster and investigating a potential performance problem with the network and need to test the network throughput between a RedHat server and a interface within the cluster.
In 7-Mode ttcp could be used for this and the command still exists within the nodeshell but i can't get it to work in cmode as it can't establish a connection between the ttcp sender and receiver.
Command on Netapp Node
xxcluster01> run -node xxcluster01-01
xxcluster01-01> priv set diag
xxcluster01-01*> ttcp -rs
ttcp -r : nbuf=1024, buflen=1024, sock_buf=262144 port=5001
ttcp-r: socket
Command on Redhat Client:
ttcp -t -s -f g -n 409600 -p 5001 10.18.40.251
ttcp-t: buflen=8192, nbuf=409600, align=16384/0, port=5001 tcp -> 10.18.40.251
ttcp-t: socket
ttcp-t: connect: Connection refused
errno=111
I'm thinking that although the command still exists it may not be possible to use as the interfaces are configured within the clustershell and the nodeshell therefore has no route to the network. Although hopefully i'm doing something wrong or missed a step to get it to work in cmode. Any idea?
