IBM Storwize V7000 Unified Problem Determination Manual page 207

When you have logged on, select Monitoring > Events. You can work with two
separate event logs:
v To work with events for the file modules, select the File tab. No fix procedures
are available to be run. From the Storwize V7000 Unified Information Center,
look up the errors.
v To work with events for the storage system, select the Block tab.
For the Storwize V7000 storage system, depending on how you choose to filter
alerts, you might see only the alerts that require attention, alerts and messages
that are not fixed, or all event types whether they are fixed or unfixed.
Select the recommended alert, or any other alert, and run the fix procedure. The
fix procedure steps you through the process of troubleshooting and correcting
the problem. The fix procedure displays information that is relevant to the
problem and provides various options to correct the problem. Where it is
possible, the fix procedure runs the commands that are required to reconfigure
the system.
Always use the recommended action for an alert because these actions ensure
that all required steps are taken. Use the recommended actions even in cases
where the service action seems obvious, such as a drive showing a fault. In this
case, the drive must be replaced and reconfiguration must be performed. The fix
procedure performs the reconfiguration for you.
The fix procedure also checks that another existing problem does not result in a
fix procedure that causes volume data to be lost. For example, if a power supply
unit in a node enclosure must be replaced, the fix procedure checks and warns
you if the integrated battery in the other power supply unit is not sufficiently
charged to protect the system.
If possible, fix the alerts in the order shown to resolve the most serious issues
first. Often, other alerts are fixed automatically because they were the result of a
more serious issue.
After all the alerts are fixed, go to "Procedure: Checking the status of your
system" on page 197.
Problem: Another system may be using the system IP address
Another system may also be connected to your network, using the same IP address
that is used for management communications to the Storwize V7000 system. This
problem is also known as a duplicate IP address.
The system IP address of the Storwize V7000 is set when the USB initialization of
the Storwize V7000 is successfully completed. It is possible for this to happen even
if the IP address is already used by another system on your network.
It is also possible that somebody could setup another machine on your network
which uses the IP address that your Storwize V7000 system is already using.
The result is that communications can go to and come from the wrong system
causing intermittent file module to Storwize V7000 system CLI communication
problems.
To check for a duplicate IP address in the local network you can attempt to use the
arping Linux command on another machine in the same subnet as the control
enclosure For example:
arping -c 2 -w 3 -I eth0 <V7000 system IP address>
