I have an older MacPro 2013 running 12.7.6

I have two Pegasus 2 R8 arrays, one connects and works fine, the other shows up in system report on my mac but the Promise utility software does not see it. I have used the same port and the same thunderbolt cable that is working for one device but I am still having no luck with the second. Any thoughts or ideas?

edit:

promise utility 4.06.0000.04 (C04)

I am not sure the firmware on the R8 since I cannot get into it.

Hi Dennis,

I'm not sure 4.06.0000.04 is compatible with Monterey. And 4.06.0000.04 is not fully compatible with the Pegasus 2.

Please try this Utility.

Regarding the non-working Pegasus 2, the chassis may have failed.

Old firmware is an issue with Apple Silicon Macs, but I am not aware of any issues with old firmware and Intel Macs.

This may not help, but it works more often than you might believe. Please connect the non-working Pegasus 2 to the Mac. Unplug the power cord leaving the Thunderbolt cable plugged in. Click the power button 5 or 6 times and wait 30 seconds. Then plug the power cord back in.

Thank you for the advice to try but unfortunately that did not work. It is just strange that I can see it on the mac system report on the thunderbolt section.

Hi Dennis,

The Thunderbolt circuitry seems independant of the motherboard. You will see the Pegasus at the Thunderbolt port immediately after you plug the Pegasus power cable in and before the Pegasus has had time to boot.

Being seen on the Thunderbolt port does not mean that everything is OK. But if the Thunderbolt port can't see the Pegaus, neither can the driver and if the driver can't connect you won't see anything, the volume won't mount and Promise Utility won't see the Pegasus.

Let's try one more test. Please unplug the power cable from the Pegasus, unseat all the drives (don't pull them out of the chassis, just pull them back maybe 1/2 inch), then plug in the power cable and see if the Pegasus boots without drives. If you get a red power button this way than that's a chassis fault and the motherboard is not booting.
