Locating A Disk Group
You can physically locate and identify all of the physical disks that comprise a selected disk group. An LED blinks on
each physical disk in the disk group.
To locate a disk group:
1. In the AMW, select the Storage & Copy Services tab.
2. Right-click on a disk group and select Blink from the pop-up menu.
The LEDs for the selected disk group blink.
3. After locating the disk group, click OK.
The LEDs stop blinking.
4. If the LEDs for the disk group do not stop blinking, from the toolbar in AMW, select Hardware → Blink → Stop All
Indications.
If the LEDs successfully stop blinking, a confirmation message is displayed.
5. Click OK.
Creating Standard Virtual Disks
Keep these important guidelines in mind when you create a standard virtual disk:
• Many hosts can have 256 logical unit numbers (LUNs) mapped per storage partition, but the number varies per
operating system.
• After you create one or more virtual disks and assign a mapping, you must register the virtual disk with the
operating system. In addition, you must make sure that the host recognizes the mapping between the physical
storage array name and the virtual disk name. Depending on the operating system, run the host-based utilities,
hot_add and SMdevices.
• If the storage array contains physical disks with different media types or different interface types, multiple
Unconfigured Capacity nodes may be displayed in the Total Unconfigured Capacity pane of the Storage & Copy
Services tab. Each physical disk type has an associated Unconfigured Capacity node if unassigned physical
disks are available in the expansion enclosure.
• You cannot create a disk group and subsequent virtual disk from different physical disk technology types. Each
physical disk that comprises the disk group must be of the same physical disk type.
NOTE: Ensure that you create disk groups before creating virtual disks. If you chose an Unconfigured
Capacity node or unassigned physical disks to create a virtual disk, the Disk Group Required dialog is
displayed. Click Yes and create a disk group by using the Create Disk Group Wizard. The Create Virtual
Disk Wizard is displayed after you create the disk group.
To create standard virtual disks:
1. In the AMW, select the Storage & Copy Services tab.
2. Select a Free Capacity node from an existing disk group and do one of the following:
– From the menu bar, select Storage → Virtual Disk → Create → Virtual Disk.
– Right click on the Free Capacity and select Create Disk Group.
The Create Virtual Disk: Specify Parameters window is displayed.
3. Select the appropriate unit for memory in Units and enter the capacity of the virtual disk in New virtual disk
capacity.
4. In Virtual disk name, enter a virtual disk name of up to 30 characters.
5. In the Map to host list, select an appropriate host or select Map later.
