I've got a 10-year-old Promise Pegasus R6 with six Seagate Green drives (5TB each) loaded. This thing has been a tank.
This morning a power transformer blew up in spectacular fashion a half-a-block away and likely surged my household. The only thing affected appears to have been my Pegasus. It threw an error on one of the drives.. fine by me! It's configured as RAID5 so I just swapped it out with a fresh spare, and expected it to rebuild.
Some odd behaviour ensued.
First, it was double-beeping, to indicate the dead drive. It appeared to be running smoothly, howeever, as it was still mounted in the OS and was at least reading data.
The double-beeps stopped when I popped in the new drive. For a while.
Second, I was initially able to view the drive etc via the Promise Utility. This eventually stopped, shortly after I started working on it. I tried updating the drivers and the Utility just to be sure, but they appear to be unable to communicate.
After letting it do its thing for 6-7 hours upon replacing the drive I decided all was not kosher and started to try to diagnose the problem.
- After power cycling the R6, the beeping continues.
- The (replaced) dead drive (Slot2) looks like it might be restoring (blue activity lights), but after 8 hours or so.. nothing has happened.
- The power light appears Orange -- in the manual this is supposed to indicate it's booting up.
- I was able to briefly make the R6 happy by pulling all six sleds. Then, when I re-inserted them, it returned to beeping.
- The Promise Utility refuses to load the management screen, though the app is running.
- The R6 is visible in Apple's "System Information" diagnostic tool as a Thunderbolt device. I can't remember whether it's supposed ot list the drives or not -- probably not.
- The double-beeping continues.
I wonder whether I interrupted a multi-day restore by rebooting the R6? And whether that might have destroyed the RAID once and for all? Only the drives in Slot1 and Slot2 are showing activity. The lights on all the drives are now blue.
