EFSSG1000I The command completed successfully.
Verify that communication from the file module to the control enclosure is now
possible by running the
lssystem command on the Storwize V7000 Unified
management CLI:
>ssh admin@v7000-unified
[kd01ghf.ibm]$ lssystem
Changing the cluster IP of the file modules:
If the cluster IP address of the file modules is not known, or has been incorrectly
set, the value can be changed by logging into the system using a console.
Connect a keyboard and monitor directly into the front of the file module which is
the active management node. Login as a user with administrative access rights:
v
Login: admin
v Password: <default is admin>
View the current cluster IP setting using the
lsnwmgt
command:
>$ lsnwmgt
[kd27lf5.ibm]$ lsnwmgt
Interface Service IP Node1 Service IP Node2 Management IP Network
Gateway VLAN ID
ethX0 9.115.160.221 9.115.160.222 9.115.160.220 255.255.248.0 9.115.167.254
EFSSG1000I The command completed successfully
You may receive the following error:
$ lsnwmgt
EFSSG0026I Cannot execute commands because Management Service is stopped. Use startmgtsrv
to restart the service.
This is an indication that the node you are currently connected to is not the active
management node. Plug the keyboard and monitor into the other node, login again
and retry the
lsnwmgt
command.
To change the file module cluster IP to its new value, use the
chnwmgt
command:
Here is an example:
>$ chnwmgt –mgtip 9.115.160.210 -- netmask 255.255.255.0 –gateway 9.115.160.254
Checking the physical status of the Ethernet ports:
The following procedures require physical access to the system. If your link is not
connected, perform the following actions to check the port status each time until it
is corrected or connected.
v
Examine the Ethernet ports LEDs. The activity LED flashes when there is activity
on the connection. The link state LED must be permanently on. If it is off, the
link is not connected.
