See quite a few devices in our deployment kicking this error in the last week or so. A couple of them we were able to power cycle to get back online to only have the error come back later.
Looking for the cause and fix for this problem.
Thanks
The “Registration failure: 105 - Deregister” error usually means the SAS denied your device’s registration—please try checking device IDs, network connectivity, and can perform a full deregister and re-register cycle.
