Hello thanks for choosing Dell. [URL] can use OMSA.
Hi,  looking to expand the number of disks from 4 to 8 in a RAID5 group on a R640 with a PERC H740P mini controller. o/s is Ubuntu18.04.5 LTS (Bionic Beaver). Would like to confirm that this procedure [URL] is applicable to the PERC H740P mini controller as the procedure shows a PERC H740P adapter.  Thank you
