troubleshooting tips
If you purchased optional software for the Data Domain system such as
Replicator or Retention Lock, the licenses are enabled on your Data Domain
system prior to shipment. You need to configure them for use. Details on
configuring the optional software can be found in the
EMC Data Domain
Operating System Administration Guide.

The Data Domain system provides multiple protocols for data access: NFS,CIFS,
VTL, and DD Boost. You need to configure one or more protocols for data
access, depending on your environment. You also need to configure the clients
for accessing the Data Domain system with the protocol of your choice.
nFS
The NFS configuration section in the configuration utility sets up the NFS
clients to allow access to
/backup
on the Data Domain system. You also need
to set up the NFS clients to allow access to
/backup
on the Data Domain
system. This can be done using the following steps:
4
Create a mount point (directory) such as
/dd/rstr01/backup
and
create an administrative mount point such as
/dd/rstr01/ddvar
.
4
NFS mount the directories on the new mount points. For example:
mount -F nfs -o hard,intr,vers=3,proto=tcp,
rstr01:/backup /dd/rstr01/backup
mount -F nfs -o hard,intr,vers=3,proto=tcp,
rstr01:/ddvar /dd/rstr01/ddvar
4
Add the following lines to the file
/etc/vfstab
(the file name may be
different depending on your UNIX-based system). The lines mount the
directories at every reboot. For example:
system:/backup - /dd/rstr01/backup nfs - yes
hard,intr,vers=3,proto=tcp
system:/ddvar - /dd/rstr01/ddvar nfs - yes
hard,intr,vers=3,proto=tcp
4
To cause backup software to abort when the system is not mounted,
create a backup directory within the mounted file system, such as
/dd/rstr01/backup/disk1
.

ciFS
The CIFS configuration section in the configuration utility sets up the CIFS
clients to allow access to
/backup
on the Data Domain system. You also
need to set up the CIFS clients to allow access to
/backup
on the Data
Domain system. For additional configuration information, see the specific
Data Domain Integration Documentation at
https://my.datadomain.com/US/en/integration.jsp
