Also I guess, what is the best way to determine which host is the master and which is the slave?

I found how how to check this with


iscsi-cfg status

To avoid any confusion here, I'll separate the various points:

- XenCenter connectivity does not relate to or have any affect on HA. So, "visible" downtime is not real downtime. If you are interested in real downtime, then rely on the alerting system built into HA-Lizard or consider xentop to watch your machines recover in real time

- An HA event should take ~ 1 minute (depending on settings - could be much faster or slower). This is irrespective of whether XenCenter is connected.

- I don't think it is normal for the slave to not show its network interfaces

I'll take a look into xentop, thanks for that.

Is there a way to force Xencenter to reconnect to the host?

As for the last response, XenServer showed the nics as unavailable is that just a hardware check that the system is doing?

It appears to be a hardware check that XenServer is performing.

After a minute or so the NICs come backup. Albeit the console doesn't show it without a refresh.

PS guess I'm just a bit nervous or anxious and really want to confirm that everything is working as intended.

There is a way, but I don't think it works as you intend. You can play with the settings. Frrom XenCetner Tools->Options->Connection->Connection Timeout

Not sure what this could be

Also because I'm probably an ID-10-+

I need to enable HA from the ISCSI cli and not from within XenCenter, right?
