Chapter 5. Control enclosure

Find out how to troubleshoot the control enclosure, which includes the use of error
codes, problem scenarios, software, and removal and replacement instructions.

Storwize V7000 system interfaces

The Storwize V7000 system provides a number of user interfaces to troubleshoot,
recover, or maintain your system. The interfaces provide various sets of facilities to
help resolve situations that you might encounter. The interfaces for servicing your
system connect through the 1 Gbps Ethernet ports that are accessible from port 1
of each canister. You cannot manage a system by using the 10 Gbps Ethernet ports.
You can perform almost all of the configuration, troubleshooting, recovery, and
maintenance of the storage system from within the Storwize V7000 Unified
management GUI or the CLI commands that are running on the Storwize V7000
file modules.
Attention: Do not use the Storwize V7000 system interfaces directly unless you
are directed to do so by a service procedure.
Use the initialization tool to do the initial setup of your system. Use the Storwize
V7000 Unified management GUI or the Storwize V7000 system management GUI
to monitor and maintain the configuration of storage that is associated with your
systems. Perform service procedures from the service assistant. Use the
command-line interface (CLI) to manage your system.

Service assistant interface

The service assistant interface is a browser-based GUI that is used to service
individual node canisters in the control enclosures.
You connect to the service assistant on one node canister through the service IP
address. If there is a working communications path between the node canisters,
you can view status information and perform service tasks on the other node
canister by making the other node canister the current node. You do not have to
reconnect to the other node.
When to use the service assistant
The primary use of the service assistant is when a node canister in the control
enclosure is in service state. The node canister cannot be active as part of a system
while it is in service state.
Attention: Perform service actions on node canisters only when directed to do so
by the fix procedures. If used inappropriately, the service actions that are available
through the service assistant can cause loss of access to data or even data loss.
The node canister might be in service state because it has a hardware issue, has
corrupted data, or has lost its configuration data.
Use the service assistant in the following situations:
