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:  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:  The following examples open the SA GUI: 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. http://1.2.3.5/service http://1.2.3.4/service 82  Implementing the IBM Storwize V5000 Gen2 with IBM Spectrum Virtualize V8.2.1 GLYPH<SM590000> SA access address: GLYPH<SM590000> Management address: GLYPH<SM590000> http(s):// service IP address of a node /service  GLYPH<SM590000> http(s):// cluster IP address of your cluster / service  GLYPH<SM590000> Details about node error codes and hints about how to fix the node error GLYPH<SM590000> Service tasks, such as restarting the Common Information Model object manager  (CIMOM) and updating the worldwide node name (WWNN) GLYPH<SM590000> Basic configuration information, such as configuring IP addresses GLYPH<SM590000> Status information about the connections and the node canister
