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.
