NOTE: When creating virtual disks using software RAID controllers, the information related to the member physical disks

of 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.
