1. Set up the Dell OpenManage Repository at http://linux.dell.com/repo/hardware, like this:
wget -q -O - http://linux.dell.com/repo/hardware/latest/bootstrap.cgi | bash
2. Install OpenManage Server Administrator:
yum install srvadmin-all
Other possible choices are : srvadmin-base, srvadmin-webserver, srvadmin-storageservices
3. Make sure the TCP port 1311 is open in IPtables. If not, add this line :
-A INPUT -p tcp -m tcp -s 0.0.0.0 --dport 1311 --tcp-flags SYN,RST,ACK SYN -j ACCEPT
(*0.0.0.0 should be replaced by the allowed management IP. Remove “-s 0.0.0.0” completely to allow all IPs)
