Associating LUN Names to Virtual Disks Identifying Controllers
If the LUN count is below the minimum requirements:
1
Verify that more than one LUN is mapped to the host group. The
minimum number of LUNs required is 2.
2
If the number of LUNs is less than 2, add LUNs to meet the

Description Determining which LUNs in the PowerVault NAS Manager are
virtual disks in the Modular Disk Storage Manager.
Work aro und Open the NAS Manager web interface and go to System
ManagementMaintenanceAdd Luns. This page displays all
LUNs that the PowerVault NX3500 cluster has access to (assigned
to the PowerVault NX3500 host group). Each LUN can be
identified using its world-wide name. In the NAS Manager web
interface, the LUN's world-wide name is preceded by a prefix.
Open MDSM and go to the Logical tab and click Virtual D isk.
The virtual disk world-wide identifier is displayed in the Properties
pane. This workaround enables you determine which virtual disks
are assigned to the NAS file system.
Description Identifying PowerVault NX3500 controllers.
Work aro und To identify a controller, use the LCD located on the front panel of
the PowerVault NX3500 controller. The LCD displays
systemname.controller#.
For example, NX3500.Controller0
