Associating LUN Names To Virtual Disks 

Description

Determining which LUNs in the NAS Manager are virtual disks in the Modular Disk 
Storage Manager (MDSM).

Workaround

Open the NAS Manager web interface and go to Cluster Management → 

Maintenance → Add Luns. This page displays all LUNs that the NAS cluster solution 

has access to (assigned to the NAS cluster solution 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 Disk. 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.

NAS IDU Failed To Discover Any Controllers

Description

NAS IDU failed to discover any controllers.

Cause

IPV6 may not be enabled on your workstation.

Workaround

Enable IPV6 support on your management workstation.

Attach Operation Fails

Description

The operation to attach the controller to NAS cluster fails.

Workaround

• Connect a keyboard and monitor to the controller that failed the attach operation, 

and view the error message to determine why the attach operation failed.

• Verify the following:

– While the controller was detached, the IP assigned to it on the client network 

was not allocated to another host. While the controller is detached, it loses its 

identity, including IP addresses. When it is attached, its identity is applied back 

to the controller, including the IP addresses.

– Verify the default gateway is in the Primary subnet by using the NAS Manager. 

In Cluster Management → Network Configuration, view the default gateway. 

In Cluster Management → Subnets, to view the Primary subnet on the client 

network. If the default gateway is not in the Primary subnet, change the default 

gateway. For attach to succeed, the default gateway must be pingable.

• After an attach operation fails, the controller must manually be reset to standby 

mode. This is done by connecting a keyboard and monitor to the controller that 
failed attach, and pressing the system identification button key 

, as directed by 

the on-screen instructions.

Controller Taking Long Time To Boot Up After Service Pack Upgrade

Description

The controller takes a long time to boot up after upgrading the service pack of the 
controller firmware.

Workaround

• Connect a keyboard and monitor to the controller that is taking a long time to 

boot up.

• If the system is booting, and is at the boot phase, let the upgrades finish. This can 

take up to 60 minutes to complete.
