UniFi ToughSwitch Crashing Hosts

[DalekSec]

Strange one here! This morning i needed to restart one of our toughswitches, and moments later one of our Host servers failed all its VMs onto the other. Thought nothing of the switch at the time. Rebooted it again hour or so ago. Once again Host servers fails over. So i then did it once more just to see it wasn't a red herring! and once again it failed over. Any idea what might be causing this? I remember my old boss saying he had to build them off domain as they caused problems with the default IP.

 

Firmware Version: SW.v1.3

Build Number: 18472

Found the problem, the default IP is in the same range as the SAN and Hosts. So even though post install we have changed the IP it loads up with the default for a few seconds! Long enough to cause it to fail over....

Should your SAN and hosts not be on a separate VLAN?

ISCSI traffic shouldn't really share a collision domain.

Honestly, im not 100% sure how they are connected. I don't deal with the working of it! My boss is away today I will speak it though with him tomorrow

Guessing they're just using a low IP. I mean our ISCSI was setup originally on the 192 range, but starting 100+
