Hi All
we have an MSA 2040 storage with one of its disks failed and as a result its disk group was in a degraded state.
we replaced the disk with the exact same model "ST4000NM0034" and the storage ddetected the disk. I then selected the disk as the global spare, but I cannot see that the storage uses the disk to rebuild its RAID and the disk group is still in a degradede state.
below is the output of the "show disks" commands with disk serial numbers hidden.

we have done below trying to resolve this issue with no success.
1: upgrading the storage controller firmware to the latest one
2: upgrading disks firmware to the latest one
3: setting the global spare disk back to Available, Rescaning storage disk channels and setting it back to the globa spare again.
4: restarting both storage controllers one at a time.
as said, none of the above resolved the problem. the storage is out of warrranty and I was hoing I can get a solution to this issue as a fear further disk losses may result in data loss.
Thanks
