Pegasus R6 not mounting

Venkatachalam Settu posted this 02 March 2017

Hi Jonas,

What is the light status of the unit and drives?

What is the last change made on the unit?

Are you able to access Promise Utility?

Thank you,

Jonas Peterson posted this 03 March 2017

Blue lights, no changes has been made on the unit for quite some time. I cannot access Promise Utility.

Raghuraman Kannan posted this 03 March 2017

Hi Jonas,

Can you confirm if the Pegasus is visible in the MAC system report ?

You can also attach the MAC system report by using the below steps

Apple Icon > About this Mac > System Report > Choose 'File' & 'Save'.

If you have registered your product with promise, you can also visit https://support,promise.com and open a case with the logs for our review.

Thank you !

Hi all - I was wondering what the solution to this was. After trouble shooting it turns out it is my Pegasus R (which has been super trusty for the past 4 years) is now not mounting. I followed the insructions on how to check the Thunderbolt port and sure enough it is showing up deep in the Apple menus, just not on desktop/disk utility like it usually does. I too have about 8TB of footage/projects I can't afford to lose. How does one get Pegaus back on track or even to a point where you can transfer everthing you need?

See image for System Report showing it is connecting way somewhere somehow.

I have a first generation R6 that stopped mounting without warning. After talking with various reps I was told it's because of the firmware in the unit and that it's no longer supported so Promise can't help me. I'm desperate to get my files back. I understand I can get a Pegasus2 and put the old drives in there, but before I do that, is there anything else that can be done that won't cost me thousands of dollars?

Me too any luck getting R6 to mount?

Hi I found this....

Recovering a RAID Drive that won't mount: FIXED!

I was running a 2 x 2TB, RAID 1 on a FW800 enclosure, with over 600GB free. The array was listed as degraded in Disk Utility. I tried to rebuild the set, thinking it was just a logic error. When I saw the rebuild time was well over 3 days, I broke the mirror, thinking I would be able (as the message box indicated) use each drive separately.

As it turns out, the enclosure died, and after I broke the mirror, neither volume would mount. No matter what I tried I couldn't get it to mount. The volume was greyed-out in the Disk Utility GUI, and Drive Genius wouldn't touch it.

I searched for weeks, and finally found the answer here: http://dice.neko-san.net/2010/07/repairing-appleraid/

In short, I ran 'diskutil list' from terminal and located a partition labeled "Apple_RAID_Offline".

In my case it was '/dev/disk1' with an identifier of 'disk1s2' and an index of '2' and contents as 'GPT part - 52414944-5F4F-11AA-AA11-00306543ECAC'. The GUID-looking number in the contents refers to the type of partition, in my case "Apple_RAID_Offline" (source: http://developer.apple.com/library/mac/#technotes/tn2166/_index.html)

Then I ran 'gpt show disk1' to list the partition data for '/dev/disk1'. This gave me the start and size. I copied the output to textedit then ran removed the partition manually with this:

'gpt remove -1 2 disk1'

This removed the partition data, not the volume contents.

Then I re-added the partition with the type "Apple_HFS" with a GUID of "48465300-0000-11AA-AA11-00306543ECAC".

The command looks like this:

'gpt add -b *start* -s *size* -t 48465300-0000-11AA-AA11-00306543ECAC disk1'

You'll want to replace *start* and *size* with the output from 'gpt show disk1'.

The instant I did this, I could mount my drives!!

My data is like this...

sh-3.2# gpt show disk4
        start                   size             index     contents
            0           1                          PMBR
            1           1                        Pri GPT header
            2       32                    Pri GPT table
           34           6
           40        409600        1          GPT part - C12A7328-F81F-11D2-BA4B-00A0C93EC93B
       409640 62507136944    2          GPT part - 48465300-0000-11AA-AA11-00306543ECAC
62507546584       262151
62507808735           32        Sec GPT table
62507808767            1           Sec GPT header

what do i need here?

'gpt remove -1 2 disk4'

and

'gpt add -b *start* -s *size* -t 48465300-0000-11AA-AA11-00306543ECAC disk4'

anyone?

I'm facing the same problem with my Pegasus R6, my MAC can't read and show the message uninitialized.

There are many data in my RAID drive and want it back seriously. Pls let me know how can I get it back and what is the step to do. Thanks.

Benjamin Roach posted this 05 June 2019

I'd love to follow this up - did anyone have any success here? I'm cautious about hitting up Terminal, having a bash and potentially doing more damage without some guidance from the Promise team first. Would love to know if there's a list of things we can check through to get our data initialised so when can migrate off their legacy systems.

My Promise 2 R6. Stopped mounting today. I have an ongoing project on it. Did anyone solve this? OMG what a nightmare!

Tim Vogel posted this 12 September 2019

I am having the same problem. All ligths are normal on my R6. I'm running Blackmagic Designs Intensity Extreme through the Thunderbolt connections. I've tried it with and without. Nothing is working. I have tried the Promise Utility and the app opens but nothing is available. No interface. Menu options all greyed out. Attached are images and troubleshooting options described above. I need serious help with this issue.

Thanks in advance for help and support.

Almost same problem with my Pegasus R6 unit. The device is not mounting, however the Promise utility can access the device and report everything is operational (green check marks). Anybody solved the Pegasus units not mounting problem... Disk util can see the device, but it is not coming up as a volume. Any help is welcome.

My r6 stopped mounting suddenly. I have been using a converter to plug the thunderbolt cable into the new firewire on my 2019 imac. I feel like the converter might have fried the thunderbolt port. (Both of them actually have stopped working.) Has anyone had this problem?

I can't see it in the imac system report and promise utility won't launch. It's like it doesn't exist but the blue lights are on and it's humming away. It was 8TB of my work (photographer) and I need to get it off. Is there a workaround? I've swapped out all cables, swapped the converters (I have two) and tried plugging into my macbook pro. It's obviously a problem with the thunderbolt ports or the pegasus r6 reading the information coming through the ports.

Before it failed completely the hard drive was ejecting itself and then reconnecting sometimes overnight with the new computer (and converters) and I thought the power was just going out. I wonder now if it was slowly failing...

Thanks in advance for any advice. I have a support thread going with tech support but it's slow and the recommendations are basic. I need phone support really and a solution that goes beyond what I've already identified as not working.

I have hit this issue with macOS Big Sur beta 6. It turns out to be an issue with the beta OS beginning in beta 6 - beta 5 worked. You can work around the issue by installing the Pegasus drivers again. The driver install will want to Restart at the end - don't! Just leave the window open. When you run the Promise Utility you'll see your drive. (You may have to turn off your drive with the button on the drive and then turn it back on again).

Thanks for this, Brooks. I'm in the exact same spot and while it worked initially－I was even able to update the firmware－after a restart… all gone again. Are you seeing the same or is your RAID sticking around? Because I have TWO, a first-gen R4 and current R6 and neither are showing up.

I also find it very odd that the only thing offered up here is to "register and create a support ticket". How is there not anything standard one can be told to try out without all that? Especially since I'm sure that the only answer will be "we don't support Big Sur" if I do. 🙄

UPDATE:

This is ridiculous.

I literally need to "install" the driver every single time I restart! After which my RAIDs mount. Then I simply force quit the installer.

How exactly is the installer able to do the job the actual driver is supposed to do? 😒

No, you do not. There is absoluely no need to install anything. You just need to manually load the driver from a terminal after a boot. This can easily be scripted (bash, zsh, applescript) to simplify the process.

This is a response from another post, if you are going to run a beta you should expect this kind of thing to happen. Betas are test sofware, no one should ever use beta software in a production computer.

----------------------------

Hi Everyone...

For those of you on the beta channel, be advised that betas are intended for testing purposes and the beta experience includes breaking various functionality. No manufacturer supports a beta OS, not even the OS vendor. Betas are the last steps in the test process before a new OS is released.

That being said, this is a known issue and will be resolved as soon as possible after Apple releases the source code for Big Sur.

The workaround is to manually load the driver, there have been no reports of this not working.

The process is below. The first command checks to see if the driver is loaded. The second command loads the driver. The third command verifies that it is loaded.

tests-MacBook-Pro-14:~ test$ kextstat | grep -i stex
tests-MacBook-Pro-14:~ test$ sudo kextload /Library/Extensions/PromiseSTEX.kext/
Password:
tests-MacBook-Pro-14:~ test$ kextstat | grep -i stex

tests-MacBook-Pro-14:~ test$

Once loaded it may take 10 or 20 seconds for the drive to appear on the desktop.

One last thing, I do not have Big Sur beta to test with, but Catalina broke a lot of things in that extra permissions have to be granted to run many kinds of software. It's possible that Big Sur has additional permission requirements for drivers to load, checking Settings > Privacy & Security > Privacy for any unchecked premissions for drivers or Promise devices would be a good idea.

I have a 10TB Pegasus R6 Thunderbolt drive that won't mount on Mac OS X Catalina or on other Mac with the previous OS.

Symptoms:

Blue lights on in front for all drives

Promise Utility does NOT show the drive present, but it does seem to be visible to diskutil:

97 rfrench@maxwell> diskutil list /dev/disk5

/dev/disk5 (external, physical):

2: Apple_HFS PROMISE-PEGASUS 10.0 TB disk5s2

The 10TB is correct and the Apple_HSF name is correct.

However, the drive won't mount on reboot. When I try to mount the disk manually, I get:

diskutil mountDisk /dev/disk5

One or more volume(s) failed to mount

Desperate to find a way to get these files back. Can't tell if the enclosure is bad somehow or there is a fatal problem with a disk. All of them have blue lights.

Any suggestions would be most welcome - I can't find a backup of these files, so I am in serious need of ideas and help.

richard french posted this 11 October 2020

responding to my own post.

Eventually, the Promise Utility was able to find the disk array but not to mount it. It showed that one 2TB disk in the array was marked PFA. I powered down the array and replaced the bad 2TB disk with a used one from another raid system, but I was not able to rebuild it because it was recognized as having other configuration information on it. I swapped out for a completely blank replacement disk (4 TB is what I had on hand), and then the Promise Utility reported that the RAID 5 array existed but had no backup and asked if I wanted to mount it any way. I answered NO but then was not able to rebuild the array - I got an error message. I tried again and this time accepted the array as being vulnerable, and it actually mounted on the desktop and I could see that my precious files were still there! In the meantime, I was able to start the rebuild. Slow, but promising. First thing I'll do is back up my files on a completely different disk.

Here are the usual steps I follow when I get a bad disk report on Promise:

Dismount, disconnect, and turn off drive, remove bad disk, install new disk, reconnect, turn drive on Fire up Promise utility 1) unlock with password 2) change Physical Drive List Settings status from pass-thru to unconfigured, using Promise Utility and clicking on Settings->Unconfigured 3) Save, then type CONFIRM, click Confirm 4) Under Disk Array, click Rebuild (don't change Source Physical Drive or Target Physical Drive - the target physical drive should be something like PD 2:6 TB for drive 2, I think) - click confirm 5) upper light should blink red, status will say Rebuilding.... 6) click on Background Activities to see % progress 7) turn off alarm in menu bar Device/Component List/mute buzzer 8) order replacement spare

I also have a first generation R6, but it won't turn on. The power button is orange so it is getting power, but it just won't power on. I have created a support case and I am been helped. I am hoping that it is just an issue with the power supply unit and nothing else but I was wondering, is it possible to read the RAID drives using other equipment, like for example a server or a Readynas? So removing the hard drives from the R6 and reading them with any other device. I have put TB's of data on the R6 and would like to get the data back.

This shows that the stex driver was already loaded. And it's the latest driver.

The text posted was for Big Sur beta users when the driver would not load. Now Big Sur is released and the driver works fine.

You did not explain what the problem is or why you tried to load the driver. What seems to be the problem?

Exact same problem here. Everything looks ok on the utility but the raid does not mount after working perfectly for a ton of time.
I never registered it and now I get a not valid serial number when I try. I imagine it is because it is an old product. Anyway, I would like to make it work again but cannot file a report without a registered product.
Thanks for the help!

Things are getting worse. Now the two other Promise RAIDs are not mounting. One R6 and one 2 R8. Both on a Mac Pro 2013 computer with Monterrey. I tried plugging in to a macbook pro and still nothing. I booted in windows and the drive appears unformatted. In disk utility appears uninitialized. In Promise utility everything is beautifully green, I can fire up redundancy checks, media patrols and everything as if the drives were completely fine. All three were running like clockwork as of friday.
Can someone help please?
