We would like to connect two different storage boxes to <br>the hosts, which I believe will result in two storage domains in the <br>same datacenter for oVirt?<br><div><br></div>One of the storage boxes sometimes has to be powered down during <br>building maintenance (electricity, cooling, ...). Will the data center <br>with the two storage domains attached still be considered "up" when one <br>of the storage domains is no longer available?<br><div><br></div>Is it sufficient to power down the VM's with disks on the affected <br>storage domain and to put the affected storage domain in maintenance?<br><div><br></div>Will oVirt keep the datacenter "up" and keep on managing the remaining <br>VM's on the other storage domain?<br><div><br></div><br><div><br></div>One of the storage domains will be a SAS-connected external storage box. <br>There will be two SAS connections per host to the storage box so <br>multipath should see the two paths. My understanding is that anything <br>detected by multipathd is considered "FC" storage by oVirt. Is that correct?<br><div><br></div>Regards,<br><div><br></div>Rik<br><div><br></div><br>_______________________________________________<br>Users mailing list<br>Users@ovirt.org<br>http://lists.ovirt.org/mailman/listinfo/users<br></div><div><br></div></div><br>_______________________________________________<br>Users mailing list<br>Users@ovirt.org<br>http://lists.ovirt.org/mailman/listinfo/users<br></div><div><br></div></div></body></html>
