First step is to add the Dell OpenManage Repository:
wget -q -O - http://linux.dell.com/repo/hardware/DSU_16.05.00/bootstrap.cgi | bash
Befor we can start the installer we had to fix the centos repository from the xenserver. Open “/etc/yum.repos.d/CentOS-Base.repo” with your favorite editor and change the baseurl from the [base] section to:
We have to do this because this is a XenServer and not a real CentOS and you will get an error message if you don’t change this setting.
Now we are ready to go for the OpenManage installation:
yum --enablerepo=base install srvadmin-all
For the access to the webinterface we had to modify the firewall settings. Open “/etc/sysconfig/iptables” with your favorite editor and insert the following line before the COMMIT line:
-A RH-Firewall-1-INPUT -m conntrack --ctstate NEW -m tcp -p tcp --dport 1311 -j ACCEPT
Add this line if you want SNMP, too:
-A RH-Firewall-1-INPUT -m conntrack --ctstate NEW -m udp -p udp --dport 161 -j ACCEPT
Use the following command to activate your changes:
systemctl restart iptables
The last step is to start OpenManage:
To enable SNMP:
service snmpd start chkconfig snmpd on
Or reboot your server. Dell OpenManage should start with your system.
You can open “https://SERVER_IP:1311” with your browser and login with “root” and your XenServer password.
