Was having issues getting pegasus R6 to initlally connect. (no issues once connected). Tried updating firmware. After Update finished and it instructed to restart the unit, I tried by holding the power button for 30 seconds. Didn't work. Tried for up to 2 minutes. Ended up unplugging power to reboot.
On Reboot power led goes from orange than to red. All 6 drives have the top LED lit, but only the bottom have drives have the bottom led lit. Every once in a while they flicker.
System Information on Mac OS sees it on the thunderbolt port, but the promise utility does not.
