Dell LCD Custom Text

Recently I had setup a HA-pair in my environment and if I do not have my computer with me, I need the NOC guys to be able to identify which is the ‘active’ unit and I found out that writing custom text to Dell LCD panel is pretty easy after some digging.

If you have not installed OMSA, please go to this link and follow the instructions.

Next, install the IMPI tool for you to be able to read/write to the LCD panel

yum install -y OpenIPMI-tools

You just need to know 2 commands to read/write to the LCD.

To see your current content on the LCD panel

ipmitool delloem lcd info

To write your custom text to the LCD panel

ipmitool delloem lcd set mode userdefined MyCustomText

There you go, it’s so simple.

Hope someone find this useful =)

Dell: No controllers found.

I am running some random check on the system that I handle. One of the Dell server controller is undetectable for unknown reason.

[svr3:/root]# omreport storage controller
No controllers found.

Before you start to panic, run the following command

modprobe mptctl
/etc/init.d/dataeng restart

Now try to execute the controller status command again.

[svr3:/root]# omreport storage controller

Dell OMSA and R300 issue

Well, today I was deploying my Dell R300 happily when I run into some trouble.

I setup Dell OpenManage Server Administrator (OMSA) based on the instructions here.

wget -q -O - http://linux.dell.com/repo/hardware/latest/bootstrap.cgi | bash

After which, I execute this command but it complain that “No package srvadmin-all available”.

yum install srvadmin-all

After 1 hour of troubleshooting, I found a way to install OMSA.

The latest version at this point of writing for OSMA is 5.5, I have to force to install 5.4.1 first.

wget -q -O - http://linux.dell.com/repo/hardware/OMSA_5.4.1/bootstrap.cgi | bash
yum install srvadmin-all

This will works for now. Grab a coffee and wait for it to finish installing first.

After you have installed 5.4.1, let’s upgrade to 5.5 now.

cd /etc/yum.repos.d/
sed -ie 's#OMSA_5.4.1#latest#' dell-hw-specific-repository.repo dell-hw-indep-repository.repo

Before you update, let’s make sure the srvadmin services is not running first.

srvadmin-services.sh status

Now, let’s update now and check the latest version 🙂

yum update
rpm -qa|grep srvadmin-all

Expected result:

[svr3:/root]# rpm -qa|grep srvadmin-all
srvadmin-all-5.5.0-364

Let’s start your OMSA and ready to go.

srvadmin-services.sh start

Visit your OMSA at https://IP-ADDRESS:1311/

Enjoy and hope this helps…
