Creating Disk Groups and Virtual Disks
In some cases, the virtual disks may have been bound when the system was
shipped. However, it is important that you install the management software
and verify that the desired virtual disk configuration exists.
You can manage your virtual disks remotely using PowerVault Modular Disk
Storage Manager. A minimum of one virtual disk is required for an
active/passive cluster configuration and at least two virtual disks are required
for an active/active cluster configuration.
Disk groups are created in the non-configured capacity of a storage array and
virtual disks are created in the free capacity of a disk group. The hosts
attached to the storage array read and write data to the virtual disks.
NOTE:
Before you create virtual disks, you must first organize the physical disks
into disk groups and configure host access. You can then create virtual disks within
a disk group.
To create a virtual disk, use one of the following methods:
• Automatic Configuration
• Manual Configuration
Create disk groups using automatic configuration as follows:
1 To start the Create Disk Group Wizard, perform one of these actions:
– To create a disk group from unconfigured capacity in the storage
array—On the Logical tab, select an Unconfigured Capacity node,
and select Disk Group Create. Alternatively, you can right-click the
Unconfigured Capacity node, and select Create Disk Group from the
pop-up menu.
– To create a disk group from unassigned physical disks in the storage
array—On the Physical tab, select one or more unassigned physical
disks of the same physical disk type, and select Disk Group Create.
Alternatively, you can right-click the unassigned physical disks, and
select Create Disk Group from the pop-up menu.
– To create a secure disk group—On the Physical tab, select one or more
unassigned security capable physical disks of the same physical disk
type, and select Disk Group Create. Alternatively, you can right-
click the unassigned security capable physical disks, and select Create
Disk Group from the pop-up menu. The Create Disk Group window
is displayed.
