Initiative Overview 

The RHEL team has informed us that iscsid and mpathd should not be running in containers and we need to make this change to be in a RHEL supported model for RHOSO-18. 

Goals 

Migrate where the iscid daemon executes on EDPM nodes, from running in a container to running directly on the EDPM host.

• This follows the guidance received from the RHEL storage team after they became aware we had containerized these daemons
• Running the daemon on the host facilitates the host booting from an iSCSI disk

Done - Acceptance Criteria

• Testing for new deployments ensuring that iSCSI multipath works as expected
• Testing for updating existing deployments to ensure that iSCSI continues to work as expected without any impact or awareness to the customer

Question: Does mpath regression cover the testing or do we need any specific verification stories?

Out of Scope 

• iSCSI mpath should be sufficient, but FC regression tests should be available before FR5 to utilize and test also
• Removal from containers.  The containerized versions will not be utilized after this change, but we will track final removal in a related Jira to be linked

No DOCs or CI Automation impact - not customer visible, existing CI coverage in place
