iscsiadm discovery: no output with Openfiler.

I was building my own Oracle RAC 11g cluster (11.2.0.2) with Openfiler as my shared storage. Two VM’s as my rac-cluster, one VM with Openfiler as my own SAN (not using the applicance, used the iso-file).  Followed the instructions of the article of Jeffrey Hunter how to build a RAC on OEL and iSCSI, however this article is not based on VM. Will publish my experiences later on.

My Openfiler-VM (named it ‘Openfiler1′) was ready, given access to my both nodes on iSCSI-level, and now I want my rac1-node to discover the iSCSI-drives on my Openfiler-VM.

Command I used on node ‘rac1′, where ‘openfiler1′ is my Openfiler-VM, on a privileged network:

iscsiadm -m discovery -t st –p openfiler1-priv

Script for setting up ssh on RAC-nodes

Finished a RAC-course a while ago with instructor Harald van Breederode. Noticed that he used a script for setting up ssh on the nodes. Short, powerful. Used it myself with user grid and oracle while installing 11g RAC.

First of all, one file should exist on forehand: $HOME:nodeinfo. Should look like this, one noder per line:

rac1
rac2

Then the file ssh_setup.sh:
