Dell Openmanage install possible?

Post by northpoint » 2018/07/18 13:37:35

I am loading up a T610 / centos7.5 and really would like some way of managing the system. So, I m looking at Openmanage by Dell.

I have to say, Everytime I visit their site its pretty confusing. I usually go around in circles ...

Does dell support Centos7.5 for openmanage? Evidently Iam not downloading the correct file (RH7 version) it reports "not supported" when running the setup.sh. However, I do see some info on their repos but nothing on how to really setup the repo.

Wonder if anyone with centos on dells is running this or perhaps I should be looking at some other means of keeping tabs on the system. Ideally I would love to know via email when drives die ect ...

Thanks,

A mostly useless comment, but I do have OpenManage installed on my R320 running CentOS 7:

Code: Select all

$ omreport about

Product name : Dell EMC OpenManage Server Administrator
Version      : 9.1.0
Copyright    : Copyright (C) Dell Inc. 1995-2017 All rights reserved.

These days Dell is pushing DSU, but I haven't jumped on that bandwagon yet.

Are you sure it is complaining about the operating system and not your hardware?

I think dsu serves a different purpose than OMSA and I have both installed and use them. OMSA keeps an eye on the current hardware for problems, dsu allows you to update the firmware etc on all the devices that are installed.

It tells me that the O/S is not supported. Obviously then I have downloaded the wrong version:

Code: Select all

[admin@srvr OM-SrvAdmin-Dell-Web-LX-9.1.0-2757.RHEL7.x86_64_A00]$ sudo ./setup.sh
     Unrecognized / Unsupported Operating System or Architecture. This script cannot 
     continue with the installation. Select rpms from the OS folder in 
     the media that closely matches this Operating System to continue 
     with the manual install.
My thinking was RHEL7 = Centos7 but Im wrong.

Where do you get the centos7 version then? I do not seem to find it anywhere. I will keep looking though.

Ok, Found it. Had to disable selinux - imagine eh?

Ill post this in case anyone else gets so side tracked as me:

Code: Select all

curl -s http://linux.dell.com/repo/hardware/dsu/bootstrap.cgi | bash

Then do a yum install srvadmin-all

Please don't. The most you should ever need to do is run setenforce 0 to put it temporarily into permissive mode. Doing that will generate sufficient log information to be able to fix it properly using the instructions from the following links:

I will make note of that on selinux - thank you.

Well, I have to say I installed the latest OMSA and started the service and got:

Code: Select all

*** Error in `/usr/sbin/smbios-sys-info-lite': free(): invalid pointer: 0x0000000000634460 ***
Evidently this is a bug that Dell has not fixed yet. Sooooo... Perhaps there is an older version I can use?

There are numerous copies of the smbios packages around. RH shipped them as part of 7.5 (at Dell's request) but the two sides got their wires crossed and the RH ones don't (or didn't) work with the current (at the time) OMSA versions. There are also smbios packages in Dell's own repo and in EPEL and which ones you have depend on what repos you have enabled, what priorities they have set and which way the wind is blowing! The ones I am using are - I believe - from EPEL and are

libsmbios-2.3.3-7.el7.x86_64
smbios-utils-bin-2.3.3-7.el7.x86_64

Thanks,

I will then attempt to install your working versions and then reinstall OMSA.

Got it working!

Had to uninstall smbios and then re-install it. I do have the EPEL repo setup.

One fact is that its accessed over a secure connection (https://) . So, Im in looking around getting used to everything there.

Thanks for all the pointers / help.
