I was recently checking over the configuration of
a NetApp FAS 2252 to ensure it was installed correctly before it gets handed
over to a customer. In doing this I checked the High Availability section
under Cluster and then the NetApp Cluster name.
There was a yellow warning box above the NetApp
HA diagram that stated "Node NetAppNode has some LIF's that are
not in their home node", although I was confident this would not
affect the failover itself I wanted to get rid of the error.
Connectivity
to SVMs is provided through logical interfaces (LIFs). A LIF has an IP address
or World Wide Port Name used by a client or host to connect to an SVM. A LIF is
hosted on a physical port. An SVM can have LIFs on any cluster node. Clients
and hosts can access data regardless of the physical location of the data in
the cluster. The cluster will use it’s interconnect to route traffic to the
appropriate location regardless of where the request arrives. LIFs virtualize
IP addresses or WWPNs, rather than permanently mapping IP addresses and WWPNs
to NIC and HBA ports. Each SVM requires its own dedicated set of LIFs.
Open up an SSH session to the SVM mgmt IP, and
use the following command;
|
network interface show
|
This will display all of the LIF interfaces
assigned to the SVM's on your NetApp, I only have one SVM and as you can see it
has three LIF interfaces. If you look above the SVM line (circled in purple)
you will see one of the LIF interfaces is orphaned. This is what was causing
the error.
The following command can be used to re-home the
orphaned LIF interface.
|
network interface revert
-vserver vservername -lif lifname
|
If you return to the GUI interface you will
notice is warning has disappeared.
