Equallogic since they are active passive only, it can be a pretty long pause. Dell recommends setting your path params to allow for 1 minute. (btw, there's a reason why Equallogic is dead now) On 2/27/20 10:59 AM, Chris Adams wrote:
How well does oVirt handle an EqualLogic SAN controller switchover event? IIRC that can result in a short iSCSI "pause" (can't remember how long it takes) - I'm not sure what oVirt's threshold before VMs (including the hosted engine) get paused for storage timeouts.
I've got a small setup where the active SAN controller's battery has gone bad, so I need to switch to the other controller, and I'm trying to figure out the impact - do I need to shut all VMs (including the engine) down first, will they just briefly pause and then continue, etc.
