[gpfsug-discuss] subnets

[Uwe Falke]

Hi Brian, 
you might use

mmfsadm saferdump tscomm 

to check on which route peer cluster members are reached.

All,

We are setting up communication between 2 clusters using ethernet and 
IPoFabric.

The Daemon interface is running on ethernet, so all admin traffic will use 
it.

We are still getting the subnets setting correct.

Question:

Does GPFS have a way to query how it is connecting to a given 
cluster/node?  i.e. once we have subnets setup how can we tell GPFS is 
actually using them.  Currently we just do a large transfer and check 
tcpdump for any packets flowing on the high-speed/data/non-admin subnet.


Thank you,
Brian Marshall_______________________________________________
