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.

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)

Now, let’s start both from the init.d scripts:

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:

Nice. What about the init.d scripts?

[root@A1UAC3DB10 init.d]# ./PowerPath start

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

[root@A1UAC3DB10 dev]# powermt -help
