change netmask

[A.G.M. Velthof]

We do have a 2 node serviceguard cluster with netapp iscsi storage.

I want to change the netmask for the iscsi network from 255.255.0.0 to 255.255.254.0

After changing the netmask, I do a cmquerycl -c "clustername"

It gives an error: IP subnets don't match, interface lan900 on "host"

                              IP betmasks don't match, interface lan900 on "host"

Any idea what more I have to reconfigure?

SG also has subnet and netmask configuration that it monitors. Check SG configuration files or the appropriate section in SMH.

maybe I am wrong, but can I not just simple remove the ISCSI network from the cluster configuration.

It is only used for the storage and not for the serviceguard cluster itself?
