## 2.10.2 Service Assistant Tool 

The IBM Storwize V5000 Gen2, as a single I/O group, is configured initially with three IP addresses: one service IP address for each node canister, and a management IP address, which is set when the cluster is started. 

The management IP and service IP addresses can be changed within the GUI, as described in Chapter 3, “Graphical user interface overview” on page 85. 

IBM Service Assistant (SA) Tool is a web-based GUI that is used to service individual node canisters, primarily when a node has a fault and it is in a service state. A node cannot be active as part of a clustered system while the node is in a service state. The SA Tool is available even when the management GUI is not accessible. The following information and tasks are included: 

GLYPH<SM590000> Status information about the connections and the node canister 

GLYPH<SM590000> Basic configuration information, such as configuring IP addresses 

GLYPH<SM590000> Service tasks, such as restarting the Common Information Model object manager (CIMOM) and updating the worldwide node name (WWNN) 

GLYPH<SM590000> Details about node error codes and hints about how to fix the node error 

Important:  The SA Tool can be accessed by using the superuser account only. You must access SA Tool under the direction of IBM Support only. 

The Service Assistance GUI is available by using a service assistant IP address on each node. The SA GUI is accessed through the cluster IP addresses by appending service to the cluster management URL. 

If the system is down, the only other method of communicating with the node canisters is through the SA IP address directly. Each node can have a single SA IP address on Ethernet port 1. We advise that these IP addresses are configured on all of the Storwize V5000 Gen2 node canisters. 

The default IP address of canister 1 is 192.168.70.121  with a subnet mask of 255.255.255.0 . 

The default IP address of canister 2 is 192.168.70.122  with a subnet mask of 255.255.255.0 . 

To open the SA GUI, enter one of the following URLs in any web browser: 

GLYPH<SM590000> http(s):// cluster IP address of your cluster / service 

GLYPH<SM590000> http(s):// service IP address of a node /service 

The following examples open the SA GUI: 

GLYPH<SM590000> Management address: 

http://1.2.3.4/service 

GLYPH<SM590000> SA access address: 

http://1.2.3.5/service 

When you access SA by using the < cluster address >/service , the configuration node canister SA GUI login window opens, as shown in Figure 2-50 on page 83.
