We proceeded to upgrade the firmware on the R6 by doing the following:Ĭlick on Promise utility on the Menu Bar -> Check for updates. Within an hour I receive a response recommending that we upgrade the firmware and see if that resolves the issue. I still found it highly suspect that 6 drives would have failed so I ran a subsystem report and sent it off to Promise's tech support. Thankfully, this RAID was the clients versioned backup so worse case we replace the drives and reclone from the working RAID. Being that this was setup as a RAID 5 this posed some potential data loss. I wanted to document our solution in an effort to save you some time if you encounter this issue.Īfter a rather serious Florida Summertime storm all the drives on an R6 were showing up offline. After some back and forth with Promise tech support and conducting our own research we found a rather simple solution. We recently ran into an issue with the drives in the R6 showing up as Dead/Offline. They have a very robust Promise RAID setup (2 x R4 and 1x R6) with over 30TBs of storage. We have a client that does quite a bit of production work.
