Hello,
I have a number of SUSE SLES10SP2 Linux guests on z/VM 5.4, service
level 0903, each of which is a copy from a solidified (golden) image.
When using Yast, Software, Software Management to add additional
packages using an NFS mounted source, the following error messages are
occuring:
Cannot access installation media SUSE Linux Enterprise Server 10
SP2-20091218-094948.
Check that the server is accessible.
There was an error in installation source initialization.
nfs://10.214.50.143/mnt/data/SLES10SP2/DVD1/: Can't provide //media.1 from
nfs://10.214.50.143/mnt/data/SLES10SP2/DVD1

The following is the configuration/messages on the NFS server side:

At the beginning and end of /var/log/messages provided above it
identifies successful mount/unmount requests from two different Linux
guests. Now, the difference between the guests which are working and
those which are not, is that the successful guests do not have DNS
entries defined in our environment. The Linux environments on which
permission is denied do have DNS entries. What additional
configuration is required to address this?
Thanks,
Ross
