Procedure: Changing The Service Ip Address Of A Node; Procedure: Initializing A Cluster With A Usb Key; Without Using The Initialization Tool - IBM Storwize V7000 Troubleshooting And Maintenance Manual

4. If the recommended action does not provide sufficient information to determine the service action,
review the node error descriptions and service actions. Go to "Error code range" on page 76.
See the node error descriptions if you cannot access the management GUI or if the management GUI
is not reporting an alert because it cannot connect to the node. When you cannot connect to the
management GUI, follow the procedure for getting node canister and cluster information using the
service assistant. Go to "Procedure: Getting node canister and cluster information using the service
assistant" on page 41. Start with the node that displays an error. The home page shows the node
errors on the current node in the priority that you must service them. Start with the node error with
the highest priority.
5. Select a different node in the system to see the node errors on that node.
6. Attempt to service the node errors in the priority order that they are listed.
7. Use the error number as an index when reviewing the node error descriptions. The service actions for
each error are listed with the error code. Go to "Error code range" on page 76.

Procedure: Changing the service IP address of a node

This procedure identifies many methods that you can use to change the service IP address of a node.
When you change an IPv4 address, you change the IP address, the subnet, mask, and gateway. When you
change an IPv6 address, you change the IP address, prefix, and gateway.
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.
You can set either 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.
Change the service IP address.
v Use the management GUI when the management GUI and the system are operating and the system is
able to connect to the node with the service IP address that you want to change.
1. Select Configuration → Network from the navigation.
2. Select Service IP Addresses.
3. Complete the panel. Be sure to select the correct node to configure.
v Use the service assistant when you can connect to the service assistant on either the node canister that
you want to configure or on a node canister that can connect to the node canister that you want to
configure:
1. Make the node canister that you want to configure the current node.
2. Select Change Service IP from the menu.
3. Complete the panel.
v Use one of the following procedures if you cannot connect to the node canister from another node:
– Use the initialization tool to write the correct command file to the USB key. Go to "Using the
initialization tool" on page 29.
– Use a text editor to create the command file on the USB key. Go to "Using a USB key" on page 28.
