102 Configuration: Disk Groups and Virtual DisksA disk group must be organized according to its related tasks and subtasks.For example, if you create a disk group for the Accounting Department, youcan create virtual disks that match the different types of accountingtransactions performed in the department: Accounts Receivable (AR),Accounts Payable (AP), internal billing, and so forth. In this scenario, the ARand AP virtual disks probably need more capacity than the internal billingvirtual 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 hostsystems. See "Host-to-Virtual Disk Mapping" on page 125.Creating Disk GroupsYou can create disk groups using either Automatic configuration or Manualconfiguration.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 storagearray—On the Logical tab, select an Unconfigured Capacity node,and select Disk GroupCreate. Alternatively, you can right-click theUnconfigured Capacity node, and select Create Disk Group from thepop-up menu.• To create a disk group from unassigned physical disks in the storagearray—On the Physical tab, select one or more unassigned physicaldisks of the same physical disk type, and select Disk GroupCreate.Alternatively, you can right-click the unassigned physical disks, andselect Create Disk Group from the pop-up menu.• To create a secure disk group—On the Physical tab, select one or moreunassigned security capable physical disks of the same physical disktype, and select Disk GroupCreate. Alternatively, you can right-click the unassigned security capable physical disks, and select CreateDisk 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.
