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 54.
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 59 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 61 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 1 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 61 to change the service IP address to one
that works in your environment.
If you are unable to change the service address, for example, because you cannot
use a USB flash drive in the environment, see “Procedure: Accessing a canister
using a directly attached Ethernet cable” on page 64.
Problem: Management GUI or service assistant does not display
correctly
This topic provides assistance if the Management GUI or the service assistant does
not display correctly.
You must use a supported web browser. For a list of supported browsers, see
Planning > Planning for software Web browser requirements to access the
management GUI in the Information Center.
Problem: A node canister has a location node error
The node error listed on the service assistant home page or in the event log can
indicate a location error.
A location error means that the node canister or the enclosure midplane has been
moved or changed. This is normally due to a service action not being completed or
not being implemented correctly.
