OMSA failed on CentOS 7 on R730xd

Hi all,

$ cat /etc/redhat-release
CentOS Linux release 7.2.1511 (Core)

I have installed the OMSA on CentOS 7 on R730xd by following this link.
http://linux.dell.com/repo/hardware/dsu/

The installation commands are as below.

~~~
wget -q -O - http://linux.dell.com/repo/hardware/dsu/bootstrap.cgi | sudo bash
sudo yum install dell-system-update
sudo dsu --inventory
sudo yum install srvadmin-all
~~~

After the installation is complete, the program can not work
correctly. The command and error message will be as below.
~~~
$ sudo ./omreport chassis memory
Memory Information
Error : Memory object not found
~~~

Does anyone know the solution to this bug on CentOS 7?

Best regards,
Jin
