Parameter criticalPriority backgroundPriority securityType physicalDiskMediaType Description The default value is highest. The default value is low. The setting to specify the security level when creating the disk pool. All virtual disk candidates for the disk pool have the specified security type. These settings are valid: • none - The virtual disk candidates are not secure. • capable - The virtual disk candidates are capable of having security set, but security has not been enabled. • enabled - The virtual disk candidates have security enabled. The default value is none. You must use this parameter when you have more than one type of physical disk media in your storage array. Valid physical disk media are: • hdd - Use this option when you have hard disk drives. • ssd - Use this option when you have solid state disks. • unknown - Use this option if you are not sure what types of physical disk media are in the expansion enclosure. • allMedia - Use this option when you want to use all types of physical disk media that are in the expansion enclosure. The default value is hdd. Security Type The securityType parameter is valid for physical disks that are capable of self encrypting disk (SED). With SED, the RAID controller module firmware can create a key and activate the physical disk security feature. The physical disk security feature encrypts data as the data is written to the physical disk and decrypts the data as the data is read from the physical disk. Without the key created by the RAID controller module, the data written to the physical disk is inaccessible. Before you can set the securityType parameter to capable or enabled, you must create a storage array security key. Use the create storageArray securityKey command to create a storage array security key. These commands are related to the security key: • create storageArray securityKey • enable diskGroup [diskGroupName] security • export storageArray securityKey • import storageArray securityKey • set storageArray securityKey • start secureErase (physicalDisk | physicalDisks) 110
