I have or should I say had..... I don't know yet.
I have a HP Z400 with two 250GB Disks attached those were configured using the Bios Utility (Matrix Storage Manager v126.96.36.1997)
to be a RAID 0 containing two Volumes. One of the Volumes was used for the System (OS) the rest for apps and so on.
Now I managed to Add another 1TB Disk to the Array, in order to replace one of the smaller ones, using the RST Software.
After migration I wanted to remove one disk but didn't found a way to do it.
I tried to mark one Disk as non Member, which resulted in status that both Volumes where failing.
I have recreated the RAID as it was before, but the System is not able to boot anymore now.
What can I do to recover the System?
