How to Install EMC Powerpath under Oracle Linux 6

In this article we are going to show you how to install EMC Powerpath and Navisphere agent under Oracle Linux. We had to install Oracle Linux 6 and Oracle Database 12c Release 1 with EMC VNX storage Multipathing LUNS but surprisingly EMC Powerpath service was failed to run.

How to resolve this issue?

Create the repo:


[root@labsrv mnt]# cd /media
[root@A1UAC3DB10 media]# ls
OL6.0 x86_64 Disc 1 20110203
[root@A1UAC3DB10 media]# cd OL6.0\ x86_64\ Disc\ 1\ 20110203/^C
[root@A1UAC3DB10 media]# cd /etc/yum-re.repos.d/
[root@A1UAC3DB10 yum.repos.d]# ls
packagekit-media.repo
[root@A1UAC3DB10 yum.repos.d]# vi rhel-cd.repo

INSERT –[rhel-cd]

enabled=1
gpgcheck=0:wq
“rhel-cd.repo” [New] 5L, 145C written
Now to disable the other repos present:
[root@A1UAC3DB10 yum.repos.d]# cat packagekit-media.repo
[InstallMedia]

Update through yum:

When installing the PowerPath rpm the package complains about libraries present in gcc (why gcc is not fully installed by default on this distro is beyond me)

[root@A1UAC3DB10 media]# yum install gcc.x86_64 gcc-c++.x86_64

So, even with gcc for the current architecture it complains.

Hmm… still not enough. This was when I had the idea to install the gcc for a 32bits system:

That was it… it was asking for the 32 bits gcc…
Now, let’s start both from the init.d scripts:

[root@A1UAC3DB10 etc]# cd init.d
[root@A1UAC3DB10 init.d]# cd ./PowerPath start
Starting PowerPath: FATAL: Error inserting emcp (/lib/modules/2.6.32-100.28.5.el6.x86_64/powerpath/emcp.ko): Invalid module format

What the hell? Why is the 2.6.32-100 kernel here when the libraries were compiled against the old 2.6.32-71 kernel? Probably my mistake during the server installation…
Let’s change grub and restart the server:

[root@A1UAC3DB10 init.d]# cd /etc/grub /etc/grubv /etc/grubi /etc/grub.conf
“/etc/grub.conf” 21L, 1259C# grub.conf generated by anaconda

Done. Let’s check the kernel again:

Let’s try to install the CLI for naviagent again:
[root@A1UAC3DB10 NaviHostAgent-Linux-6.26.32.0.72]# rpm -ivh naviagentcli-6.26.32.0.72-1.noarch.rpm

Nice. What about the init.d scripts?
[root@A1UAC3DB10 NaviHostAgent-Linux-6.26.32.0.72]# cd /etc/init.d
[root@A1UAC3DB10 init.d]# ./naviagent start
Starting Navisphere agent: [ OK ]
[root@A1UAC3DB10 init.d]# ./PowerPath start
Starting PowerPath: done

Great. Let’s check the devices and see if PowerPath is ready to work with the luns that are going to be presented to the server:
[root@A1UAC3DB10 init.d]# cd /dev
[root@A1UAC3DB10 dev]# ls -l emcpower
crw-r–r–. 1 root root 10, 56 Jun 24 12:09 emcpower

Yep… and the powermt tool is also working:
[root@A1UAC3DB10 dev]# powermnt display dev=all
Device(s) not found.
[root@A1UAC3DB10 dev]# powermt -help
Usage:

All good now. Hope this might help someone out there scratching it’s head on a similar problem.
