How to Install Data Protector 6.0 on Red Hat Enterprise Linux 5

| Comments

Yesterday I finished the installation of a new Red Hat Enterprise Linux 5 (RHEL5) and I needed to install the Data Protector Disk Agent to backup its files. I have a Windows 2003 cell manager and a HP-UX install server that should help with the installation of the Data Protector software on UNIX/Linux/Solaris hosts… I’m quite a newbye on the topic but I was unable to install the disk agent using the HP-UX install server so here you will find instructions for the “always working” manual installation.

The first thing is to get the HP-UX PA-RISC install server CDs from HP website: if you do not have the original CDs you can get them as trial from here.

Now its time to install the Disk Agent on the server you need to backup; you need to install two packages that are not installed by default on the Red Hat Enterprise Linux 5: ncompress and xinetd. So, as root, execute the command:

Install prerequisites
$ yum install ncompress xinetd

to get the needed packages installed.

Insert the first CD of the HP-UX PA-RISC install server on the optical drive of the server and mount it:

Mount CD
$ mount /dev/hda /mnt

Now it is install time:

Install DP
$ ./

Answer all the questions the installer asks to you and finish the installation. In my installation the Data Protector agent was not correctly added to the xinetd configuration… look if you find the omni file in /etc/xinetd.d… if you do not find it create it with the following content:

xinetd service installation
service omni
socket_type = stream
protocol = tcp
wait = no
user = root
server = /opt/omni/lbin/inet
server_args = inet -log /var/opt/omni/log/inet.log
disable = no

and verify it is owned by root and with 644 permissions.

OK… we are at the end…

Restart xinetd
$ /etc/init.d/xinetd restart

As suggested by fluffy on comment #1 now you have to check if the firewall (iptables) is actually active: if the firewall is switched on you have to permit the traffic from and to port 5555 to flow regularly.

Check firewall rules
$ chkconfig --list | grep iptables
iptables        0:off   1:off   2:off   3:off   4:off   5:off   6:off

If you any on you need to modify the file /etc/sysconfig/iptables adding:

Proposed firewall rule
-A RH-Firewall-1-INPUT -m state –state NEW -m tcp -p tcp –dport 5555 -j ACCEPT

Now everything should be ok… let’s try if the Data Protector agent answers to port 5555:

Final check
$ telnet localhost 5555

That’s all… if you encounter any problem leave a comment here… I’ll try to help you.

Leave a comment even if you have a smarter method… I am very glad to learn.
