[ovirt-users] Re: Hosted engine installation oVirt 4.5 initialize lockspace volume

Have you checked if the initiator name is proper IQN and unique ?

Best Regards,

Hello,

hope, you are doing well. I try to install a new hosted engine on my 
environment to switch the storage this engine. I use following command to 
deploy the instance:

  hosted-engine --deploy --4 --ansible-extra-vars=he_offline_deployment=true

Everything works fine, except the initialization of lockspace volume. Here I 
get:

Sorry for the delay, I missed this thread.

>From ovirt-hosted-engine-setup you can configure the iSCSI storage domain,
exposed by a single iSCSI target, to be accessed over multiple portals in a
single portal group.
Once you have a running engine you can eventually complete the
configuration creating an iSCSI bond from there.
Follow this guide for that:
https://ovirt.org/documentation/admin-guide/chap-Storage.html#configuring-iscsi-multipathing

Let's now focus on the first part.
On your SAN you should create more than one iSCSI portal.
Then you should group them in a single iSCSI target portal group.
You iSCSI target should be configured to be exposed over the whole iSCSI
target portal group.
Then you have to create a LUN for the hosted-engine storage domain and
associate it with that iSCSI target.

Now, on hosted-engine-setup (via CLI or via cokpit) you should enter the IP
address or one of the iSCSI portals (and eventually one username/password
couple for the iSCSI discovery).
The iSCSI discovery process will report back your iSCSI targets and the
address of other iSCSI portals in the same iSCSI target portal group; each
of them will be a path so if you have more than one iSCSI portal in a
single iSCSI target portal group you will have multipath.

Next step is choosing one of the listed iSCSI targets, then
hosted-engine-setup will list the LUNs there and you will be able to choose
one of them to be used for the hosted-engine storage domain.

The engine appliance is distributed within ovirt-engine-appliance rpm; you
can simply install that on the first host.
