Dell PowerVault NX3600 - Manual (Page 96)

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 required minimum LUN count of 2.
3. Try to format the system.
Associating LUN Names To Virtual Disks
Description Determining which LUNs in the NAS Manager are virtual
disks in the Modular Disk Storage Manager.
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.

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 →
