Troubleshooting Tips - EMC DATA DOMAIN DD160 Installation And Setup Manual

4 Configure the System for Data Access
The Data Domain system provides multiple protocols for data access: NFS,
CIFS, 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 on the protocol of your choice.
NFS
The NFS configuration section in the Perform Initial System Configuration 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:
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.
5 Configure Optional Software
If you purchased optional software for the Data Domain system such as
Replicator or Retention Lock, the licenses are enabled on your EMC Data
Domain system prior to shipment. You need to configure them for use.
Perform Optional Additional System Configuration
6
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 DD OS 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}

Troubleshooting Tips

For troubleshooting information see the Data Domain Support web site https://support.emc.com.
CIFS
The CIFS configuration section in the Configuration 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 specific Data Domain
integration documentation for setting up backup software from other vendors.
DD BOOST FOR OPENSTORAGE
For setting up the Data Domain DD Boost feature, see the Data Domain Boost
for OpenStorage Administration Guide .
APPLICATION INTEGRATION
For information about how to integrate the Data Domain system with backup
software, see the documentation for the applicable application.
For more information, refer to the documentation at EMC Online Support
https://support.emc.com
Details configuring the optional software can be found in the EMC Data Domain
Operating Systems Administration Guide .
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 poweroff
