1. Verify that more than one LUN is mapped to the hostgroup. The minimum number of LUNs required is 2.2. If the number of LUNs is less than 2, add LUNs tomeet the required minimum LUN count of 2.3. Try to format the system.Associating LUN Names To Virtual DisksDescription Determining which LUNs in the NAS Manager are virtualdisks in the Modular Disk Storage Manager.Workaround Open the NAS Manager web interface and go to ClusterManagement → Maintenance → Add Luns. This pagedisplays all LUNs that the NAS cluster solution has accessto (assigned to the NAS cluster solution host group). EachLUN can be identified using its world-wide name. In theNAS Manager web interface, the LUN's world-wide nameis preceded by a prefix.Open MDSM and go to the Logical tab and click VirtualDisk. The virtual disk world-wide identifier is displayed inthe Properties pane. This workaround enables youdetermine which virtual disks are assigned to the NAS filesystem.NAS IDU Failed To Discover Any ControllersDescription 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 FailsDescription The operation to attach the controller to NAS cluster fails.Workaround • Connect a keyboard and monitor to the controllerthat failed the attach operation, and view the errormessage to determine why the attach operationfailed.• Verify the following:– While the controller was detached, the IPassigned to it on the client network wasnot allocated to another host. While thecontroller is detached, it loses its identity,including IP addresses. When it isattached, its identity is applied back to thecontroller, including the IP addresses.– Verify the default gateway is in thePrimary subnet by using the NASManager. In Cluster Management →96
