I've been running a Pegasus R6 12 TB RAID 5 array with no troubles for years and now I am having a big issue.
5 months ago I had to replace a disk marked as « dead » in Slot 1, did it and rebuilt with success. I replaced it with a new disk same brand and model as the ones that came with the array (Seagate barracuda 2TB). The R6 has been running fine afterwards.
Three weeks ago, again, I had to replace another disk marked as « dead » in Slot 5, did it and rebuilt with success. Did replace with brand new same kind of drive (Seagate barracuda 2TB). The R6 has been running fine till today.
Today, I was running the unit fine and suddenly after half an hour running, two drives went dead at the same time, including the one freshly replaced in Slot 5 three weeks ago and another one in Slot 6 :(
In the "Events" section of promise utility, it reports that "Physical disk is marked as DEAD due to removal"??? I didn't even touch the Unit, it's sitting still!
Unit is powered through a UPS so there is no question of any power loss or problem, and its sitting on a sturdy dedicated shelf without any kind of movement and in a fair air temperature, firmware is up to date so I have no clue why that happened!
What can I do? Is it possible to simply buy two new drives, replace the dead ones and rebuild?
I am running latest version of Promise Utility on Windows 7 ultimate
