T110 Perc S100 controller migrate RAID0 to RAID1
I have a T110 with 2x500GB in RAID0 using the integrated Perc S100 RAID controller. For enhanced reliability I would like to migrate the OS (SBS) to RAID1, with 2 new 1TB disks. However, I can not get this done. I've tried making virtual disks, hot spares,.... On OMSA I see "no task available" for the 2 500GB disks in RAID0, and only "Unassign Global Hot spare" for the 2 1TB disks. When I try to reconfigure Virtual Disk1, I only see Connector 0 with the 2 500GB disks, stating 0.00GB free. Options are greyed out, and upon clicking "next", there is "Virtual Disk 1 Reconfigure Error", for different reasons like not enough physical disk space, max number of virtual disks, reconfiguration is not supported at this time, etc....

No, that is not a function of RAID controllers … bare metal software would have to be aware of the S100 (or Windows-based, like WinPE in which you can load Windows-based drivers, as the S100 is a Windows only device). Might be able to use something like EASEUS Todo Backup to copy the OS from source to target while "live".

You can't remove/shrink RAID levels … there is no available disk space to shuffle data to condense 2 disks to 1, regardless of actual storage capacity. You will need to backup/restore to a different array. You may be able to, if you have the capacity, to put a second array in (RAID 1), then clone one VD to another.
