<div dir="ltr">Hi Bill,<div>in order to provide HA, the hosted-engine HA services should be able to autonomously connect the shared storage from each hosted-engine involved host.</div><div><br></div><div>The storage configuration is in /etc/ovirt-hosted-engine/hosted-engine.conf</div><div><br></div><div>So:</div><div><div style="font-size:12.8px"><span style="font-size:12.8px">1. set global-maintenance mode</span><br></div><div style="font-size:12.8px">2. shutdown the engine VM</div><div style="font-size:12.8px">3. manually edit <span style="font-size:small">/etc/ovirt-hosted-engine/hosted-engine.conf</span> on each host </div><div style="font-size:12.8px">4. here we have a delicate point: on restart <span style="font-size:12.8px">ovirt-ha-agent will connect the new storage server but the issue is that it will not call disconnectStorageServer on the previously connected one so you will probably end with VDSM that has still a reference also to the previous location and this can cause timeouts and so on if not available. Restarting VDSM is probably not enough since the the symlinks under /var/run/vdsm will not be refreshed if they are already there ( ) so I'd suggest to reboot all the hosts to avoid any possible issue.</span></div><div style="font-size:12.8px">5. exits global maintenance mode</div></div></div><div class="gmail_extra"><br><div class="gmail_quote">On Tue, Feb 2, 2016 at 6:12 AM, <a href="mailto:bill@taney.com">bill@taney.com</a> <span dir="ltr"><<a href="mailto:bill@taney.com" target="_blank">bill@taney.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div style="word-wrap:break-word"><span style="background-color:rgb(255,255,255)"><font color="#404040" size="2">In a hosted-engine deployment has anyone had to migrate to a new iSCSI SAN? I can not figure out how to move the engine(s) to a new iSCSI target.. The SAN’s can fully replicate to one another and I can move the LUN to the other device but don’t see how to stop the engine and change the settings for it’s iSCSI target to another IP/IQN. Any direction would be greatly appreciated - I am looking for any method to get this done, we have to retire the old SAN - Thanks.</font></span></div><br>_______________________________________________<br>
