Example 1: System configuration output from lsnode displays similar to the
following example:
[admin@kq186wx.mgmt001st001 ~]# lsnode
Hostname IP Description Role
mgmt001st001 172.31.8.2 active management node management,interface,storage
mgmt002st001 172.31.8.3 passive management node management,interface,storage
Product version Connection status GPFS status CTDB status Last updated
1.3.0.0-50a OK active active 8/30/11 8:36 PM
1.3.0.0-50a OK active active 8/30/11 8:36 PM
EFSSG1000I The command completed successfully.
[admin@kq186wx.mgmt001st001 ~]#
Example 2: Output for lsnode for a management service that is not running is
similar to the following example:
[admin@kq186wx.mgmt002st001 ~]# lsnode
EFSSG0026I Cannot execute commands because Management Service is stopped.
Use startmgtsrv to restart the service.
2. Determine the service IP addresses for the file modules hosting a management
node role by running the CLI command lsnwmgt. Output that is similar to the
following example is displayed:
[admin@kq186wx.mgmt001st001 ~]# lsnwmgt
Interface Service IP Node1 Service IP Node2
ethX0 9.11.137.128 9.11.137.129
Management IP Network Gateway VLAN ID
9.11.137.127 255.255.254.0 9.11.136.1
EFSSG1000I The command completed successfully.
The following table describes the nodes that are identified by the command:

mgmt002st001 Service IP Node2
Performing management node role failover on a “good” system
Use this procedure to complete a failover process when both file modules appear
to be operating correctly.
About this task
If both file modules are operating correctly with regard to management services,
perform the following procedure to failover the active management node to the
passive management node.
Procedure
1. Open an SSH connection to the service IP of the file module hosting the passive
management node role.
Refer to “Determining the service IP for the management node roles” on page
183, if necessary.
2. To initiate the management services on the passive node and perform the
switchover from the active management node, run the startmgtsrv command.
Note: If you run the startmgtsrv command from the node that is becoming
active, you first need to run the setcluster command to set the cluster
