Configuration: Disk Groups and Virtual Disks

A disk group should be organized according to its related tasks and subtasks. 

For example, if you create a disk group for the Accounting Department, you 

can create virtual disks that match the different types of accounting 

performed in the department: Accounts Receivable (AR), Accounts Payable 

(AP), internal billing, and so forth. In this scenario, the AR and AP virtual 

disks probably need more capacity than the internal billing virtual disk.

In Linux, the host must be rebooted after deleting virtual disks to reset the 

/dev entries.

Before you can use a virtual disk, you must register the disk with the host 

systems. See "Host-to-Virtual Disk Mapping" on page 116.

You can create disk groups using either Automatic configuration or Manual 

configuration.
To create disk groups using automatic configuration:

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 

Disk Group from the pop-up menu.

The Introduction (Create Disk Group) window is displayed.

2 Click Next.

The 

Disk Group Name and Physical Disk Selection window is displayed.
