GPT secured partition appeared after RAID5->RAID6 migration

[SAljoshin]

Hello!

We have 7 identical servers with RAID5 configured. There were JBODs connected and RAID5 was successfully migrated to RAID6. But after restart all servers showed in Disk manager all drives in offline status with GPT secured partition and the sire of old RAID5 and RAID6 volume in the end. All works, but after every restart we can find in Event Logs that Windows Server try to identify each drive but can understand that it is a part of RAID and ignores.

All 7 servers behave the same after restart. I also attached screenshots of Disk Manager and RAID web Console. Also a part of Event Logs.

Hello Sergei,

In order to get more clarity of the issue, could you please share with us the model number of the server system, mother board, and RAID card that you are using?

Hello Franklin!

Here you go:

S1200SPLR

E3-1245V6

RMS3CC040 (has 2xRAID1 connected, one RAID1 contains OS)

+

RSP3MD088F(has 8x6TB connected directly+24x6TB in external JBOD box and all are in RAID6 now)

Hello,

Thank you for replying back.

To resolve the "protective" issue on a GPT partition so as to make it usable again, have you tried following the next two workarounds:

Option 1. Diskpart command-line utility

Option 2. Third-party GPT to MBR conversion software

As additional information: I found the following article from Microsoft about the EventID: 158; https://support.microsoft.com/en-us/help/2983588/event-id-158-is-logged-for-identical-disk-guids.

Please let me know in order to verify the information and proceed with the next step.

Hello Emeth,

Seems like there is some kind of misunderstanding.

I will try to explain in additional.

1. In the beginning there were: RAID1(2xSSD for OS), another RAID1(2xSSD) and RAID5 (8 HDD). Everything worked fine and one volume was displayed per array. As it should be.
2. We connected JBOD to RAID controller with additional 24HDDs and put RIAD5 to migrate to RAID6. Everything was fine and displayed correctly. After migration proccess all was fine and status was OK.
3. We did a restart to server and discovered such picture as shown at the picture. For some reason there are 32 "volumes" with RAID5 size and secured partition, which are all OFFLINE and one RAID6 correct size Dick and ONLINE.

These are surveillance servers and I am very short in operations there. Moreover as you can see these "disks" are offline and I don't really understand what will be the result if I put one of them online? with it crash the RAID?

Hi,

Thank you for your patience and the time you have been waiting for my response.

I would like to remark on the importance of having an up to date backup as there is a chance of data loss based on the issue.

By any chance, do you have the possibility to install the RWC3 on your system? This is the software used for RAID management and monitoring for Intel RAID controllers.

Intel® RAID Web Console 3 for Windows*

Intel RAID Web Console 3 User Guide

Could you please so kind and provide us a copy of the complete RAID log? In order to gather this information please follow the next article:

How to Extract the Full RAID Log for Intel® RAID Controllers

Also, It would be good to understand what kind of JBOD product (brand and model) is connected to the external port on the RSP3MD088F RAID controller.

I will be waiting for your outcome in order to proceed with the next step.

Hello Sergei,

So, as far as our management software goes (RWC3) all volumes are in an optimal state.

Since the issues are showing within Disk Management (offline partitions), I would recommend to open up a ticket with Microsoft support as well.

If the migration process took place without errors then at a logical volume level all should be fine. Partition wise that would need to be checked with the OS manufacturer.

Have a wonderful day.

Hello Emeth,

If you suggest it is a OS issue, I will discuss it with Microsoft, but I believe there will be no help as usual. Standard answer from Microsoft is "Make a backup, create a clean OS installation and install all updates."

Anyway thank you very much for help and investigation.
