Description Martin Tessun 2015-12-04 07:42:22 UTC

Description of problem:
The Overcloud will be deployed using the "overcloud-full" image.
This image will be deployed on ALL Overclodu nodes and this image has an iSCSI initiator name:
cat /etc/iscsi/initiatorname.iscsi
InitiatorName=iqn.1994-05.com.redhat:d0c58fd0f44

This iSCSI initiatorname is the same on ALL Overcloud nodes and if you don't change this name the Live Migration will not work at all in an environment with the same IQN on ALL nodes!

Version-Release number of selected component (if applicable):
OSP-d 7.1.0
OSP 7.0.2

How reproducible:
always

Steps to Reproduce:
1. Install 2+ Overcloud nodes
2. Check that the /etc/iscsi/initiatorname contains the same entry on all nodes

Actual results:
The content is identical across all nodes

Expected results:
Every node should have its own unique initiator-id

Additional info:
I fixed this problem by a Pre-Deployment script for the Controller and Compute Nodes:

# Set unique iSCSI IQN
IQN=$(/sbin/iscsi-iname)
/bin/crudini --set /etc/iscsi/initiatorname.iscsi '' InitiatorName "$IQN"

This (or something similiar) sould be added to the installer.

bz1244328 - blockdev cannot see logged iscsi target after live migration
