Problem: Cannot connect to the service assistant
If you are unable to display the service assistant on your browser, you have several options.
- Each node canister runs its own service assistant. Each service assistant can be used to administer the node on which it runs and also the other node canister, provided there is no connectivity error preventing the nodes from communicating. This means there are several paths through which service tasks can be administered to a node.
- The URL to point your browser at to access a service assistant always looks like IP address/service. The IP address can be a service IP address of a node, or it can be a system IP address. If you use a system IP address you will be connected to the service assistant on the configuration node.
- Service addresses are configured on Ethernet port 1 of each 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 Ethernet connections for details.
- A default service address is initially assigned to each node canister (see Problem: node canister service IP address unknown). It might not be possible to connect to a node canister service assistant if multiple node canisters on the same network are using the default IP addresses.
- To find the IPv4 and IPv6 addresses that are configured on the node, go to Problem: node canister service IP address unknown.
- Ensure that the node is configured with valid service addresses.
- Verify that the IP address, subnet, and gateway are specified correctly for IPv4 addresses on your Ethernet network.
- Verify that the IP address, prefix, and gateway are specified for the IPv6 addresses on your Ethernet network.
- Verify that the address is not used by another device on your Ethernet network.
- If any of the values are invalid, see Procedure: Changing the service IP address of a node canister. If you are unable to change the service address because you cannot use a USB flash drive in the environment, see Procedure: Accessing a canister by using a directly attached Ethernet cable.
- Ping the service IP 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.
- You cannot connect to the service assistant if the node canister is not able to start the Storwize® V3700 machine code. To verify that the LEDs indicate that the node machine code is running, see Procedure: Understanding the system status using the LEDs.
