Number of hot spares in the storage array. Use
integer values. For information about hot spares,
see Assigning Global Hot Spares.
segmentSize
Amount of data (in kilobytes) that the RAID
controller module writes on a single physical disk
in a virtual disk before writing data on the next
physical disk. Valid values are 8, 16, 32, 64, 128,

commands are related to the security key:
• create storageArray securityKey
• export storageArray securityKey

• set storageArray securityKey
• start secureErase (drive | drives)
• set PhysicalDisk securityID
