Hello  Tom


Thank you very much for your help.
I was able to mount the 2000 NFS files after your modifications
via:

for i in `seq 1 2000`
do
     mount   -t nfs -o intr,hard,tcp  solaris10-02:/fs/DISK/disk$i  =

/fs/solaris10-02/DISK/disk$i
    sleep  1
 done


But , if i remove the sleep command the

nfs bindresvport: Address already in use

error appears again.

On solaris and sgi clients the above command works correctly without the =

sleep command.

So the machine takes about 1 hour to mount all nfs filesystems.

Any idea?

Best wishes

Bernhard
