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 congure them for use. Details
conguring the optional software can be found in the
EMC Data Domain
Operating System Administration Guide
.
Congure Optional Software
5
The Data Domain system provides multiple protocols for data access: NFS,
CIFS, and DD Boost. You need to congure one or more protocols for data
access depending on your environment. You also need to congure the
clients for accessing the Data Domain system on the protocol of your choice.
NFS
The NFS conguration section in the Perform Initial System Conguration sec-
tion 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:
4Create a mount point (directory) such as /dd/rstr01/backup and
create an administrative mount point such as /dd/rstr01/ddvar.
4NFS 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
4Add the following lines to the le /etc/vfstab (the le name may be
dierent 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
4To cause backup software to abort when the system is not mounted,
create a backup directory within the mounted le system, such as
/dd/rstr01/backup/disk1.
CIFS
The CIFS conguration section in the Conguration Wizard 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.
VTL OPTIONAL LICENSE REQUIRED
For the VTL software option, see the Data Domain technical note
Integrating
the Data Domain Appliance VTL with SANs.
See the specic Data Domain
integration documentation for setting up backup software from other vendors.
DD BOOST FOR OPENSTORAGE OPTIONAL LICENSE REQUIRED
For setting up the Data Domain DD Boost feature, see the
EMC Data Domain
Boost for OpenStorage Administration Guide
.
APPLICATION INTEGRATION
For information about how to integrate the EMC Data Domain system with
backup software, see the documentation for the applicable application.

ADDITIONAL SYSTEM CONFIGURATION
Any system command that accepts a list, such as a list of IP addresses, accepts
entries separated by either commas or spaces. See the
EMC Data Domain
Operating System Command Reference Guide
for command details.
Give access to additional backup servers:
# nfs add /backup {*|client-list}
[options]
Add users to the email list that reports system problems:
# alerts add email-list
Add users to the system report email list:
# autosupport add email-list
Enable FTP or TELNET:
# adminaccess enable {ftp|telnet}
Add remote hosts to use FTP or TELNET:
# adminaccess add {ftp|telnet}
fqdn-host-list
Add a user:
# user add name [priv {admin|user}]
Change a user’s password:
# user change password username
TO SHUT DOWN THE SYSTEM
Important: Never shut down the system by pressing the power button.
Instead, enter:
# system powero
