Dell MD3200, MD3220 Creating Disk Groups, Introduction Create Disk Group window is displayed

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.

NOTE: In Linux, the host must be rebooted after deleting virtual disks to reset the /dev entries.

NOTE: 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.

Creating Disk Groups

•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.
