10.6 Creating Logical Device

This section explains how to create a logical device using SED drives. Mixing of drives to create the logical device is not allowed, for example; mixing of block sizes (512 Bytes and 4K), interface types (SATA, SAS, NVMe), drive types (HDD and SSD), and SED types (Opal and Enterprise). To create a logical device, the SED drive must be either in OFS or the ownership status should be MCHP Owned.

Additional device types with the following combination are listed along with the other device type in the Create Logical Device window only when the SED based encryption is configured/enabled.

SATA SED Opal HDD 512
SATA SED Enterprise HDD 512
SATA SED Opal SSD 512
SATA SED Enterprise SSD 512
SAS SED Opal HDD 512
SAS SED Enterprise HDD 512
SAS SED Opal SSD 512
SAS SED Enterprise SSD 512
SATA SED Opal HDD 4K
SATA SED Enterprise HDD 4K
SATA SED Opal SSD 4K
SATA SED Enterprise SSD 4K
SAS SED Opal HDD 4K
SAS SED Enterprise HDD 4K
SAS SED Opal SSD 4K
SAS SED Enterprise SSD 4K

Note: The device types are listed only if the possible drive combination exists.
