Virtual-disk name
Type a string to identify the virtual disk. This string must adhere to the following conventions:

  • Permissible characters include uppercase letters (A-Z), lowercase letters (a-z), numerals (0-9), hyphens (-), and underscores (_).
  • The first character cannot be a numeral.
  • The name cannot begin with an abbreviation commonly used to specify the object type, for example, the name cannot begin with VDisk, VDISK, or vdisk.
If you leave this field blank, a name is generated automatically. If you create multiple virtual disks, the name is used as a prefix.
I/O group
Select the I/O group. By default, Let the system choose is selected. Other options are the actual I/O groups on the cluster.
Managed-disk group
Select the managed-disk group. The managed-disk groups are listed using the following convention:
MDisk-group name (<N>)
where <N> is the available capacity. After you select the managed-disk group, the managed disks in the managed-disk group are displayed.
Add managed disk
Click to add a managed disk to the managed-disk group.
Round robin sequential assignment to managed disk
Select the check box to ensure that the virtual disks are assigned to the managed disks in a round-robin manner. If selected, the number of virtual disks must equal the number of managed disks selected in the managed-disk table.

Clear the check box to ensure that all virtual disks are created on a single managed disk. If the check box is cleared, there must be only one managed disk selected in the managed-disk table.

Format virtual disks
Select the check box to ensure that the virtual disks are formatted (written with zeros) after they are created.
