Full Discussion: NIM NFS file system cannot unmount

I am guessing you are running a
Code:
nim -o define -t mksysb ...

command to perform these backups and it is the client that is not able to unmount.

To debug - you could start with using rpcinfo -p <NIM> | grep nfs to see if the nfs demons are recognized.

The other question I would have is whethr this client has more than one IP address and/or nim route back to the nim server. If it is, the way I debugged the interface being used by default is the telnet/ssh to the nim server (use the <NIM> name as hostname, and then after login, use the command "who" to show which IP address/hostname is recognized as originating IP address.

Compare these values to what a "working" client returns.

My gut feeling, if I read corrently it is the same client that fails, is that there is a configuration difference between this client and the one that succeed.
