v Use a USB key to find the service address of a node. For more information, go to
"Procedure: Getting node canister and system information using a USB key" on
page 49.
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: Unknown service address of a node canister" on page 42. 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 57.
v You cannot connect to the service assistant if the node canister is not able to
start the Storwize V7000 code. To verify that the LEDs indicate that the code is
active, see "Procedure: Understanding the system status using the LEDs" on
page 49.
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 55 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
Ethernet network. If necessary, change the network configuration or see
"Procedure: Changing the service IP address of a node canister" on page 57 to
change the service IP address of a node.
v A default service address is initially assigned to each node canister. The service
IP address 192.168.70.121 subnet mask 255.255.255.0 is preconfigured on Ethernet
port 1 of the upper canister, canister 1. The service IP address 192.168.70.122
subnet mask 255.255.255.0 is preconfigured on Ethernet port 2 of the lower
canister, canister 2.
You might not be able to access these addresses because of the following
conditions:
– These addresses are the same as the addresses that are used by other devices
on the network.
– These addresses cannot be accessed on your network.
– There are other reasons why they are not suitable for use on your network.
If the previous conditions apply, see "Procedure: Changing the service IP
address of a node canister" on page 57 to change the service IP address to one
that works in your environment.
