NOTE: It is recommended to create a virtual disk with a minimum size of 10 GiB or more.
|
NOTE: If the number of virtual disks per physical disk exceeds the maximum supported limit, then an undefined behavior may be observed in the Server Administrator UI or CLI.
|
NOTE: When creating virtual disks using software RAID controllers, the information that is related to disks that are 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.
