IBM Flex System V7000 Storage Node Introduction and Implementation Guide
4.5 Service Assistant
The primary use of the Service Assistant is when a node canister in the IBM Flex System
V7000 Storage Node enclosure is in service state. The node canister might be in service
state because it has a hardware issue, has corrupted data, or has lost its configuration data.
The node canister cannot be active as part of a system while it is in service state.
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 all node canisters in a system are
in service state. Use the Service Assistant in the following situations:
򐂰
When you cannot access the system from the management GUI and you cannot access
the Flex System V7000 Storage Node to run the recommended actions
򐂰 When the recommended action directs you to use the Service Assistant.
You can also perform the following service-related actions using Service Assistant:
򐂰 Collect logs to create and download a package of files to send to support personnel.
򐂰
Remove the data for the system from a node.
򐂰 Recover a system if it fails.
򐂰 Install a software package from the support site or rescue the software from another node.
򐂰 Upgrade software on node canisters manually versus performing a standard upgrade
procedure.
򐂰 Configure a control enclosure chassis after replacement.
򐂰 Change the Service IP address that is assigned to Ethernet port 1 for the current node
canister.
򐂰
Install a temporary SSH key if a key is not installed and CLI access is required.
򐂰 Restart the services used by the system.
4.5.1 Changing the Service IP address
There are multiple methods that you can use to change the Service IP address of a storage
node canister and which method to use depends on the status of the system and the other
node canisters in the system. Follow the methods in the order shown until you are successful
in setting the IP address to the required value.
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.
Tip: The Service Assistant does not provide any facilities to help you service expansion
enclosures. Always service the expansion enclosures by using the management GUI.
Tip: You can set an IPv4 address, an IPv6 address, or both, as the service address of a
node. Enter the required address correctly. If you set the address to 0.0.0.0 or
0000:0000:0000:0000:0000:0000:0000, you disable the access to the port on that protocol.
