What the first poster said about Dell's recommendations are accurate (I'm a long time Equallogic user)
I worked with Equalogic in the past. Doesn't it have the ability to replicate to a partner Equalogic? If so, replicate, once complete do a failover to the new one. That may be a simplistic approach and not sure if it's Dell best

Do you have an idea how long will it take ?
No, it has been years and years since I had to do a switchover on an EqualLogic (they mostly just run). I know I've read of others using EqualLogic's for oVirt, so I'm hoping for someone who's experienced a switchover...
Keep in mind that in case the domain is declared unavailable (reached a threshold , which I doesn't know) , all VMs using it will be paused and oVirt will try to recover them once the storage is back available.
Right - with the hosted engine on the SAN, I am also curious how that is impacted (how will the engine HA tooling handle a pause). -- Chris Adams <cma@cmadams.net> _______________________________________________ Users mailing list -- users@ovirt.org To unsubscribe send an email to users-leave@ovirt.org Privacy Statement: https://www.ovirt.org/site/privacy-policy/ oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/F44KYWA6SPMFUR... _______________________________________________ Users mailing list -- users@ovirt.org To unsubscribe send an email to users-leave@ovirt.org Privacy Statement: https://www.ovirt.org/site/privacy-policy/ oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/Z6ER5NXH67X7TQ...

I don't think that it will work. oVirt 's internal mechanisms do not rely multipath to provide an error up in the stack , instead if it cannot write/read in the defined threshold - it will still asume that the storage domain is down. At least that was discussed on the mail list some time ago and I could be wrong. Best Regards, Strahil Nikolov
