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.
