Problem: Cannot Connect To The Service Assistant - IBM Storwize V7000 Unified Problem Determination Manual

3. The service assistant home page lists the node canister that can communicate
with the node.
4. If the service address of the node canister that you are looking for is listed in
the Change Node window, make the node the current node. Its service address
is listed under the Access tab of the node details.
If you know the service IP address of any node canister in the system, you can log
into the service assistant of that node. Follow the previous instructions for using
the service assistant, but at step 1, point your browser at the /service directory of
the service IP address you know. If you know a service IP address is 11.22.33.56,
point your web browser to 11.22.33.56/service.
Some types of errors can prevent nodes from communicating with each other; in
that event, it might be necessary to point your browser directly at the service
assistant of the node that requires administering, rather than change the current
node in the service assistant.
If you are unable to find the service address of the node using the management
GUI or service assistant, you can also use a USB flash drive to find it. For more
information, see "Procedure: Getting node canister and system information using a
USB flash drive" on page 213.

Problem: Cannot connect to the service assistant

This topic provides assistance if you are unable to display the service assistant on
your browser.
You might encounter a number of situations when you cannot connect to the
service assistant.
v Check that you have entered the "/service" path after the service IP address.
Point your web browser to <control enclosure management IP address>/service for
the node that you want to work on. For example, if you set a service address of
11.22.33.44 for a node canister, point your browser to 11.22.33.44/service.
v Check that you are using the correct service address for the node canister. To
find the IPv4 and IPv6 addresses that are configured on the node, go to
"Problem: Node canister service IP address unknown" on page 206. Try
accessing the service assistant through these addresses. Verify that the IP
address, subnet, and gateway are specified correctly for IPv4 addresses. Verify
that the IP address, prefix, and gateway are specified for the IPv6 addresses. If
any of the values are incorrect, see "Procedure: Changing the service IP address
of a node canister" on page 220.
v You cannot connect to the service assistant if the node canister is not able to
start the code. To verify that the LEDs indicate that the code is active, see
"Procedure: Understanding the system status using the LEDs" on page 213.
v The service assistant is configured on Ethernet port 1 of a node canister. Verify
that an Ethernet cable is connected to this port and to an active port on your
Ethernet network. See "Procedure: Finding the status of the Ethernet
connections" on page 218 for details.
v Ping the management address to see if the Ethernet network permits the
connection. If the ping fails, check the Ethernet network configuration to see if
there is a routing or a firewall issue. Check that the Ethernet network
configuration is compatible with the gateway and subnet or prefix settings.
Check that you have not used an address that is used by another device on your
