Configuration: Disk Groups and Virtual Disks

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 Logical tab.
2 Select the appropriate disk group and from the toolbar select Disk 

Group Blink
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 

Storage Array Blink Stop All Indications.

If the LEDs successfully stop blinking, a confirmation message appears.

5 Click OK.

Keep these important guidelines in mind when you create a 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 

appear in the Logical pane of the Logical 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.

Ensure that you create disk groups before creating virtual disks.
