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 cannot find the service address of the Storwize V7000 Gen2 node using the
management GUI or service assistant of a different node, two options remain:
v You can connect directly to the service assistant of a node using the technician
port of the node, as described in “Procedure: Initializing the Storwize V7000
Gen2 system using the technician port” on page 274.
v You can also use a USB flash drive to find the service address of the node. For
more information, see “Procedure: Getting node canister and system information
using a USB flash drive” on page 255.
Table 76. Default service IP addresses
Canister and port IPv4 address IPV4 subnet mask
Canister 1 (left) port 1 (left) 192.168.70.121 255.255.255.0
Canister 2 (right) port 1 (left) 192.168.70.122 255.255.255.0
Problem: node canister service IP address unknown
You can use several methods to determine the service address of a node canister.
A default service address is initially assigned to each node canister, as shown in
Table 77 on page 245. Try using these addresses if the node has not been
reconfigured, and the addresses are valid on your network.
If you are able to access the management GUI, the service IP addresses of the node
canisters are shown by selecting a node and port at Settings > Network > Service
IP Addresses.
If you are unable to access the management GUI but you know the management
IP address of the system, you can use the address to log into the service assistant
that is running on the configuration node.
1. Point your browser at the /service directory of the management IP address of
the system. If your management IP address is 11.22.33.44, point your web
browser to 11.22.33.44/service.
2. Log into the service assistant.
The service assistant home page lists the node canister that can communicate
with the node.
3. 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.
