Drobo

B800i not available via iscsi, appliance is also gone from dashboard

Hi All,

My Drobo B800i connected to file server via iscsi. I added two hard drives to drobo B800i a few weeks back, then it is doing data protection progress. In the middle of data protection progress, our datacenter had power outage, Drobo was shutdown. After power is resumed, the drobo hard drive attached to file server was not accessible. I tried to reconnect drobo box via iscsi initiator, then file server stuck, drobo appliance was also disappeared from dashboard.

I then tried to power down drobo, after powered it back on, dashboard was able to detect the appliance, then data protection kicked in again. However file server stuck again, then drobo appliance was gone from dashboard. I removed drobo from file server, rebooted it again, leave it run data protection, I have about 5.9TB data saved on drobo, data protection run over a week but not completing, I did not see any progress. So I tried to mount drobo again to a test server via iscsi initiator, I don’t want have file server stuck. As soon as drobo was mounted to iscsi, it was gone from dashboard. I don’t know what is going on, I obtained log, but not sure what I can do to get it back. I want to copy all data out first, then see if we need to buy a new one. Could anyone help me on this? Any hint is welcome. Below is errors from log:
