Hi, we have FAS3020c and this morning at around quartert to 6 DFM reported that the partner node is dead. I ran into the office and checked the lights on the harddisks on the shelves. No amber lights! So I thought it is not a harddisk problem. I tried a cf giveback on the takeover node and this reported two disks missing on the partner node. I checked again and all lights were green. I forced a giveback and noticed that the complete aggr0 was broken.
vol status -f showed no broken disks
I turned off the disk shelve and then 3 FC disks were reported as broken. How likely is it that 3 disks fail at the same time? I mean there wasn't even notification from DFM that one of the disks had failed.
Could this be a firmware bug?
Any Ideas how to recover some of the data of the broken aggregate.
