Chapter 6. Resolving a problem
Described here are some procedures to help resolve fault conditions that might
exist on your system and which assume a basic understanding of the Storwize
V7000 system concepts.
The following procedures are often used to find and resolve problems:
v Procedures that involve data collection and system configuration
v Procedures that are used for hardware replacement.
Always use the recommended actions on the Events panel of the management GUI
as the starting point to diagnose and resolve a problem.
The following topics describe a type of problem that you might experience, that is
not resolved by using the management GUI. In those situations, review the
symptoms and follow the actions that are provided here.
The “Start here: Use the management GUI recommended actions” topic gives the
starting point for any service action. The situations covered in this section are the
cases where you cannot start the management GUI or the node canisters in the
control enclosure are unable to run the system software.
Note: After you have created your clustered system, remove hardware components
only when directed to do so by the fix procedures. Failure to follow the procedures
can result in loss of access to data or loss of data. Follow the fix procedures when
servicing a control enclosure.
Start here: Use the management GUI recommended actions
The management GUI provides extensive facilities to help you troubleshoot and
correct problems on your system.
You can connect to and manage a Storwize V7000 system using the management
GUI as soon as you have created a clustered system. If you cannot create a
clustered system, see the problem that contains information about what to do if
you cannot create one. Go to “Problem: Cannot initialize or create a system” on
page 46.
To run the management GUI, start a supported web browser and point it to the
management IP address of your system. Up to four addresses can be configured
for your use. There are two addresses for IPv4 access, and two addresses for IPv6
access. If you do not know the system management IP address, go to “Problem:
Management IP address unknown” on page 44. After the connection is successful,
you see a login panel. If you are unable to access the login panel, go to “Problem:
Unable to connect to the management GUI” on page 44.
Log on using your user name and password. If you are unable to log on, go to
“Problem: Unable to log on to the management GUI” on page 45.
