T420, raid expansion
Dear Dell
I have a Dell T420 with Windows server 2016. It has two virtual drives. C:raid1, 2 drives, D:raid5, 5drives. This leaves me one spare drive slot. I purchased another drive for the raid5 array but can't seem to find the right software to expand the array. OMSA seems to be retired, ISM doesn't work on this server and IRADC7 doesn't seem to have an expansion option. Where am I going wrong?

That depends on the type of PERC Raid controller. Its named "Online Capacity Expansion" within the manual.
