Several changes were made to the implementation of self-hosted engine RHV 4.1. This affects the way that a self-hosted environment is to be restored in a disaster recovery or migration scenario. The steps for restoring a self-hosted engine environment must be reviewed and updated. See the bugs in 'Depends On' for details of the required changes.

Lucy, just finished the customer facing KCS solution we talked about: https://access.redhat.com/solutions/2998291
Lucy, could you review the KCS? If it's good enough you we can link it in the docs, saving some time. Or even move the contents to the Docs and just put the link to the docs in the KCS. And since this also works in 4.0.7, maybe 4.0 docs also deserve it?
Thanks, Germano! And sorry for the delay. I'm assigning this one to Byron for review. Byron, can you review the KBase against our current procedures to see how extensive the updates might be?

Adding another duplicate: bug 1505798 This one is a request for instructions on restoring storage as part of this flow.
Moving to the Documentation component and removing targets to allow the docs team to review and re-triage this request.
Targeting at 4.3, to be reviewed together with bug 1482710 as part of the overall content strategy for SHE backup and restore.
Rescoping this for the 4.2 stream, given the high priority. Assigning to Tahlia for review. Tahlia, we'll review this in the context of 4.2 only, so it should follow on logically from your GA work on the deployment changes.
Setting the requires_doc_text flag to - since docs bugs don't get release notes.
Hi, I'd like to add some note to the restore procedure of the environment with several SDs and one of them is iscsi. If the restore process is running on the re-provisioned host , it probably will fail with STORAGE_DOMAIN_UNREACHABLE error . To prevent this after re-provisioning the host the user must update the /etc/iscsi/initiatorname.iscsi with the right value before the restore process starting.

This just in the case where iSCSI target doesn't accept every connection but filters them according to initiators ACL, right?
(In reply to Simone Tiraboschi from comment #91) > > This just in the case where iSCSI target doesn't accept every connection but > filters them according to initiators ACL, right? right. here is the yaml definition for iscsi: iscsi_server: "10.35.162.66" target_id: "iqn.2009-01.com.kaminario:storage.k2.22612" storages: ... iscsi_0: state: present iscsi: target: "{{ target_id }}" address: "{{ iscsi_server }}" lun_id: 20024f40058540070 override_luns: True

This is really important note, user have to understand that iSCSI mapping should be updated for the hosts, hence initiator iqn must be the same as was mapped on iSCSI target, or changed to new iqn accordingly.
Thanks, I'll add it in.
I have no objections. Moving to verified. Please reopen if there will be some additional data needed to be inserted or open a separate documentation bug on it.
Verified. Waiting to merge.
