IBM Storwize V7000, Troubleshooting And Maintenance Manual

Page: 52 / 188

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:
v
When you cannot access the system from the management GUI and you cannot
access the storage Storwize V7000 to run the recommended actions
v When the recommended action directs you to use the service assistant.
The storage system management GUI operates only when there is an online
system. Use the service assistant if you are unable to create a system or if both
node canisters in a control enclosure are in service state.
The service assistant does not provide any facilities to help you service expansion
enclosures. Always service the expansion enclosures by using the management
GUI.
The service assistant provides detailed status and error summaries, and the ability
to modify the World Wide Node Name (WWN) for each node.
You can also perform the following service-related actions:
v Collect logs to create and download a package of files to send to support
personnel.
v
Remove the data for the system from a node.
v
Recover a system if it fails.
v
Install a code package from the support inh_site or rescue the code from another
node.
v
Upgrade code on node canisters manually versus performing a standard
upgrade procedure.
v
Configure a control enclosure chassis after replacement.
v
Change the service IP address that is assigned to Ethernet port 1 for the current
node canister.
v Install a temporary SSH key if a key is not installed and CLI access is required.
v
Restart the services used by the system.
A number of tasks that are performed by the service assistant cause the node
canister to restart. It is not possible to maintain the service assistant connection to
the node canister when it restarts. If the current node canister on which the tasks
are performed is also the node canister that the browser is connected to and you
lose your connection, reconnect and log on to the service assistant again after
running the tasks.
Accessing the service assistant
The service assistant is a web application that helps troubleshoot and resolve
problems on a node canister in a control enclosure.
