CRC error during Pegasus32 R8 synchronization triggers triple-beep alert but the manual document this and the notification is hidden by default

[lgarron]

I've upgraded the storage in my PROMISE Pegasus32 R8.

After being plugged in for an hour or two, it starts emitting triple beeps continuously. It's like someone is sending Morse code of repeated S indefinitely.

The manual does not mention anything about repeated triple beeps, only double beeps (which are for rebuilding the array). PROMISE Utility Pro does not show any notifications or any issues (although the drives are going through a long synchronization).

I can mute the sound, but it's very disconcerting that:

1. There is no indication of what the sound means. For all I know, it's some sort of failure.
2. This sound has returned at least once after muting.

Downloading the service report from PROMISE Utility Pro shows:

===============================================================================
Enabled   Status    
===============================================================================
Yes       Silent    

If this happens again, I'll try to see if the status provides any useful info.

But this part looks like a bigger clue:

This does roughly match the times I heard the sounds.

That said, the terminology of the rest of the app implies that "PD 4" means "pass-through disk 4" and none of the disks are pass-through. I'll have to keep investigating.

Aha! PROMISE Utility Pro also shows these under notifications, if you click on the bell icon and then "Events".

The UI implies that only critical events would trigger a notification that shows up in the notification UI by default. It seems a bit funky to me that there's a conspicuous audible notification associated with a hidden notification by default. 🤷

Aha, the UI shows that PD 04 is indeed "physical disk 04", presumably the disk in the 4th slot from the top.

It sounds like the only thing that really tripped me up here was the fact that the triple-beeping was not reflected in the manual or the initial dropdown when clicking on the notification UI. I'll have to decide what to do about the disk, given that it's already exhibited two CRC errors.

(Also, the functionality of the "Mute/Sound" button in the app is rather confusing, but the manual explains it nearly well enough.)
