74 Implementing the IBM Storwize V5000 Gen2 with IBM Spectrum Virtualize V8.1
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 shown in
Chapter 3, “Graphical user interface overview” on page 77.
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:
Status information about the connections and the node canister
Basic configuration information, such as configuring IP addresses
Service tasks, such as restarting the Common Information Model object manager
(CIMOM) and updating the worldwide node name (WWNN)
Details about node error codes and hints about how to fix the node error
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 into any web browser:
http(s)://cluster IP address of your cluster/service
http(s)://service IP address of a node/service
The following examples open the SA GUI:
Management address:
http://1.2.3.4/service
SA access address:
http://1.2.3.5/service
Important: Service Assistant Tool can be accessed by using the superuser account only.
You must access Service Assistant Tool under the direction of IBM Support only.
