If Pegasus Manual could be that clear and simple! I know technology, but frankly, after reading the manual almost from cover to cover, I couldn’t even get to activate the greyed Rebuild button frustrating. Now rebuilding a failed 3TB drive in a pegasus R4 RAID5 thanks to you. Smile coming back.

The Promise Utility is showing a dead physical drive in PdId #4 in my Pegasus R4 array.

The dead disk is only about a year old, so I wanted to try something..

Download lg flash tool. I am on a Macintosh.

I took the 'dead' drive out of the R4 case and initialized it after I put it in an external drive enclosure on my Mac.

It initialized with no problem. I checked it with some disk utilities, and the disk appears to be fine.

In a few hours the Pegasus will totally rebuild that blown drives information. This of course happens while the drive array is STILL IN USE, which is great for a network or a computer that must be running at all times. The Pegasus arrives formatted and configured in a RAID 5 array, but you may change that to RAID 1, 2, 6, or 10 if you wish. Pegasus2 R4 - 12TB RAID System Hardware Platform Mac Operating System 10.8.5 and higher; Windows Item Weight 7.2 ounces Product Dimensions 14.1 x 12 x 13.5 inches Item Dimensions LxWxH 14.1 x 12 x 13.5 inches Manufacturer Promise Technology ASIN B0186EQ08C Is Discontinued By Manufacturer No Date First Available October 9, 2015. The Pegasus2 is the first RAID that supports Thunderbolt 2, the new communications protocol that was released with the new Mac Pro. This new protocol supports data transfer rates up to 2.2 GB/second. NOTE: That preceding paragraph is a completely true statement, but it leads to some wildly incorrect conclusions. So if you want to update the firmware in your Promise RAID, don’t leave it to the app. Instead, visit the support page, make your way to the Pegasus Series – Pegasus R4 listing, locate the firmware, and download it as a.img file. Then open the Promise Utility, and select the Firmware Update command from its Admin menu.

So I put the reformatted physical drive back into the R4 unit.

It still appears as a dead drive in the Promise Utility. (See below image.)
I cannot change its config in the Promise Utility setting because I cannot click on either of the buttons that say, 'Passthru' or 'Unconfigured.' (See below image.)
Using Terminal, I cannot clear a stale config, I cannot assign a 'config=unconfig,' I cannot take the drive offline because a message tells me that 'it is already offline,' and I cannot clear a PFA condition because a message tells me that the drive is 'in use.' (See below image.)

This all seems very weird to me.

Nothing I do can help the Promise Utility see the drive so that I can do a manual rebuild of the logical array.

I do not want to force the drive online, because the last time I did that, it caused corrupted file fragments in the 'Lost+Found' folder.

Can somebody please give me some comments or suggestions?

Thank you!

If you have a Pegasus32 series (R4/R6/R8), or are thinking of buying a Pegasus32 and would like to use it with your new Mac Pro (2019) for additional storage. This guide will allow you to use the Pegasus32 as a stand alone storage or to use (as we will demonstrate with an Pegasus R4) in conjuction with the Pegasus R4i for even greater read and write speeds, than a stand alone Pegasus R4i.

How to setup and install the Pegasus32 R4 to a Mac Pro (2019):

Required Items

Mac Pro, Pegasus32 R*, and Thunderbolt 3 cable

Will require an 'active' Thunderbolt 3 cable

9th grade shsat practice test. The next step is to install the thunderbolt 3 into one of the thunderbolt cable ports on the back of the Mac Pro, and one to the Pegasus32.

Connecting the cables should look as so

Go ahead plug in the power and video to your Mac Pro and Pegasus.

Once in macOS, you will need to install the driver for your Pegasus R32.

Click on the link below to find the driver and utility for your Pegasus.

Once the driver is installed. Download nexus fl studio 12 crack. Reboot your Mac Pro and the Pegasus will automatically power if connected via Thunderbolt 3 cable.

You will need to open Disk Utility then go to --> File --> RAID assistance.

Create a stripe with both the R4i logical volume and the Pegasus32 R4.

Once the RAID stripe is created we benchmarked.

Test Software: Blackmagic Design, Disk Speed Test 3.2

Test Hardware: Mac Pro 2019 8 core Xeon, 32gb ECC DIMMs, 580x Module, Pegasus J2i 1 x 8TB 7200rpm

The performance numbers should be similar to what is exhibited below.
