i have a netapp filer running nfs server and a redhat 8 client trying to mount the filer file system. the exports have been properly shared on the netapp filer and are being correctly mounted using an NFS client for windows (diskaccess). but i cant seem to be able to mount it on my redhat 8. i do it like this:
[root@phantom etc]# mount 172.16.50.145:/ /mnt/filer
mount: RPC: Timed out

this is the result of rpcinfo -p
[root@phantom etc]# rpcinfo -p

i have also checked the nfs entry in /proc/filesystems. its there!
what am i doing wrong?!?!?

The 172.16.50.145 ip numbers must resolve to a hostname.
So make sure that the ip numbers and hostnames are in the
/etc/hosts file on the nfs server and ass well ass on the nfsclient computer's /etc/hosts file

Or use a dns server on your network.

With regards
