NOTE: When creating virtual disks using software RAID controllers, the information related to the physical disks linked to the
virtual disk is enumerated or displayed on Storage Management after a short delay. This delay in displaying the information does
not cause any functional limitation. If you are creating partial virtual disks, it is recommended that you provide Storage
Management adequate time between each partial virtual disk creation process.
