RAID5 Array does not show up under disks

    Question

  • I have a server connected to two raid arrays. 

    Each raid array is configured as RAID5.

    After bringing up Windows 2012 with the raid arrays attached; I went to Server Manager and found one of the arrays under disks and was able to configure it as a GPT partition.

    However; the other RAID5 array was not in the list of disks.  I found it under Storage Pools.

    Why is Windows 2012 not showing this as a disk that I can configure as a disk?  I don't want to use this RAID5 array as a storage pool.

    How can I get this RAID5 array to show up under disks...where it should have been in the first place?

    Are both arrrays the same? Physical RAIDs? Or Windows software parity RAIDs?

  • It's more likely a hardware related issue. If it is a hardware RAID, try to upgrade firmware of the RAID controller to see the result.

  • They are both physical arrays.

    I will try updating the firmware and see what happens.

  • I have upgraded the RAID firmware for the controller and have the same results.

    This is a Dell server connecting to two Dell raid arrays.  When I use the OpenManage Server Administrator; both drives are showing up under "Virtual Disks".  Windows 2012 see's both disks.  But while it has one disk showing up under "Disks"; the other is showing up under "Storage Pools".

    There must be some way to change this...
