I have purchased Dell R720 server with PERC H710 Raid Controller. Initially I have configured RAID-10 with 6 SAS 300GB Drives. Installed Win2008 R2.
After deployment I come to add 2 more 300GB to array. Now I am unable to expand these two drives into existing RAID-10 neither Online nor from RAID Configuration Utility (PERC H710 Mini Bios Configuration Utility 4.03-0002)
In RAID-BIOS "Expand VB Size" option is disabled.
? how can I expand my RAID-10, and add more drives to array?
