I have two raids based on Intel RST technology:
- RAID 0 (two disks)
- RAID 5 (four disks)
Both of them were built using Intel RST feature integrated into P55 Intel chipset (ASUS P7P55D-E Premium motherboard)
That happened, the motherboard died
It was replaced by MSI P55-GD80 motherboard with the same socket/chipset and the same set of features.
All 6 sata drives were detected, but only three of them were recognized as Raid members (the second disk of the Stripe Raid set and two last disks of RAID 5 Raid set) and three others were marked as Non-RAID in the BIOS utility.
That brought both sets into failed state.
I see the same picture in the Intel RST software (Windows 7 64-bit, the latest Intel RST version) when system is booted from the dedicated non-Raid system drive.
All 6 SATA disks are presented, two Raid sets are presented (both in a failed state) with three disks and three empty slots, three "non-Raid" disks are presented.
Intel RST utility gave additional information.
All disks are shown with a correct serial numbers.
All recognized Raid disk descriptions also contain correct disk serial numbers.
But empty slots contain disk serial numbers with minor format change:
Could it be a root cause of the problem? How it could be fixed?
Thank you very much for contacting the Intel Communities Team, CawaSPb.
In this case, as you mentioned, Intel® Rapid Storage Technology will recognize the drives but, is unable to verify in which RAID were some of them, this should be caused by the motherboard that is not recognizing how the drives are set or in which RAID they should go to. At this point, please get in touch with https://us.msi.com/support MSI* support to double check this issue with them.
Thank you for the answer!
I'm not sure it should be addressed to the motherboard vendor since both motherboards are based on the same Intel P55 chipset with integrated Intel RST functionality.
Intel Raid management utility (Windows and BIOS) is provided by Intel.
It's correct that originally an issue was probably caused by wrong disks order and how they are attached to SATA ports, but the question was what to do with this when it already happened (reattaching disks to ports in a different order didn't help and kept disks in the original state (member/non-raid).
It seems, that just reassigning disks could solve the problem.
Unfortunately, Intel doesn't provide the solution for this issue even people meet the problem for years.
The third party tool may be used instead:
http://www.overclock.net/forum/320-raid-controllers-software/478557-howto-recover-intel-raid-non-member-disk-error.html HowTo : Recover Intel RAID "Non-Member Disk" Error.. - Overclock.net - An Overclocking Community
The solution is also mentioned in one of the other related threads:
The problem with that third party tool (even if it works as a charm) is that overall process is not non-disruptive.
It requires setting disks which are mentioned as a raid set members to non-raid and creating Raid set from the scratch. That forces Intel RST BIOS utility to create new empty partition table and writing it to the newly created raid set. That drops existing data.
TestDisk tool searches through the newly created raid set for deleted partitions and gives an ability to store recognized partition information in a partition table.
This tricky way requires advanced knowledge and really may finish with complete data loss.
That would be really good if Intel RST BIOS utility or Application give an ability to manually set non-raid disks as a raid members and set the order of disks in a raid set (then check if that really returns raid set into the correct state).
This may be a great advantage and can be recognized by users as an effort to solve their problems.
In this case, allow me to get more information about your system for me to perform a deeper research about this issue. Please provide me with an https://www.intel.com/content/www/us/en/support/articles/000006351/technologies.html Intel® Rapid Storage Technology report and attach to the thread the .txt file that thehttps://downloadcenter.intel.com/download/25293/Intel-System-Support-Utility-for-Windows- Intel® System Support Utility will generate.
