[?] Smart Array S100i SR Gen10 SW RAID drives are not found when RAID mode is disabled

When Smart Array S100i SR Gen10 SW RAID controller is enabled on a server and RAID mode is
disabled in the System Utility, then the drives are listed as AHCI drives or H220i drives and the RAID
controller is not found in POST or device manager. When RAID mode is enabled, the drives appear as
Smart Array S100i SR Gen10 SW RAID controller drives.
Below is the procedure to correct the problem.
1. Press the <F9> key during the startup process to access System Utility.
2. In the System Configuration menu, select BIOS/Platform Configuration (RBSU) → Storage
Options → SATA Controller Options → Embedded SATA Configuration → Smart Array SW
RAID Support.

up and restore the data on the drives.
[?] The Smart Array controller does not show logical drives after moving drives to a new server or JBOD

Be sure to follow all drive roaming rules when migrating drives.
