After registry one ironic compute service,start one baremetal server report one error.
Baremetal instance had already Complete PXE boot，and Bare machine installed successfully.
However, when the instance is restarted, it cannot run normally and an error is reported.

[Julia Kreger (juliaashleykreger)]

A few different things.

1) iscsi based deployment is no longer supported by ironic. In fact, it has been deprecated for some time and *removed*.
2) Validate errors are to be expected. The module does not, and should not manage inventory inside ironic and this is a failure of the user to supply details required to provision a node.
3) Nova failing a deployment because of issues which do not relate. In this case, image_source is actually supplied by nova, *and* the errors are that the iscsid unit simply does not exist which is from a version of ironic which is expecting it to be a running service on the host. I'm unsure if we should actually fix that.

This bug does not indicate any problem with configurations applied by puppet-ironic and sounds more like a core ironic issue and needs investigation from ironic side.

Please report this issue to the ironic project if you are still facing it.
