Now type the following: phydrv -a online -p 1 phydrv -a online -p 2 phydrv -a online -p 3 phydrv -a online -p 4 On the Mac, open the Terminal app and run: promiseutil See below for instructions on forcing the drives back online.
Unfortunately, the option to force the drives online isn't available through the Promise Utility GUI but has to be done via the Terminal application. The issue was resolved by forcing the drives back online. I then started to do a bit more research and come to find out that others have experienced the logical drive of the Promise RAID going offline after abruptly losing power. Choose reboot & restart the unit.Īfter the unit rebooted the drives were still showing offline. After the update, click on subsystem information on the Promise Utility window -> Shutdown/Reboot.

It would prompt for updating the firmware, update the firmware. 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.
