Planning for configuration

Use the following worksheets to record configuration data that you need as you install a system. Depending on the model of your system, different configuration data might be necessary.

Storwize V7000 Gen2 enclosures

One or two management addresses must be allocated for the system. The first management address is assigned for use on Ethernet port 1 (1 Gbps) of each node canister. If a second management address is allocated, then the system assigns this address for use on Ethernet port 2 (1 Gbps) of each node canister. The system assigns the management addresses to one node canister in the system at any time to provide access to system configuration and administration functions such as the management GUI. IPv4 and IPv6 protocols can be used.

When a 10 Gbps Ethernet adapter is installed in Storwize® V7000 Gen2 canisters, there are seven Ethernet ports. The 1 Gbps Ethernet ports are numbered 1, 2 and 3, and the 10 Gbps Ethernet ports are numbered 4, 5, 6, and 7. Only the 1 Gbps Ethernet ports can be used for configuration or management. Either the 1 Gbps or 10 Gbps Ethernet ports can be used for iSCSI or FCoE connections.

With code level 8.1.1 or higher, the Storwize V7000 Gen2 canister can support two 10 Gbps Ethernet adapters. When two 10 Gbps Ethernet adapters are installed, there are 11 Ethernet ports. The 1 Gbps Ethernet ports are numbered 1, 2 and 3, and the 10 Gbps Ethernet ports are numbered 4, 5, 6, 7, 8, 9, 10, and 11. Only the 1 Gbps Ethernet ports can be used for configuration or management. Either the 1 Gbps or 10 Gbps Ethernet ports can be used for iSCSI or FCoE connections.

A service address is also allocated to Ethernet port 1 of each node canister in the enclosure. The node canister retains the service IP address, providing convenient access to node canister configuration and service functions, such as the service assistant GUI and CLI for that node canister; IPv4 and IPv6 protocols can be used.

In addition to the Ethernet ports that are used to connect and manage the system, the Ethernet port that is labeled T is the technician port.
Important: Do not connect the technician port to a switched network. When service is required, a personal computer is connected directly to the technician port for initialization and troubleshooting tasks.
The management IP address is required when the system is initialized. Use Table 1 to record the management IP addresses allocated for use by the system.
Table 1. Management IP address configuration
Configuration item Value Description
Port 1
Management IPv4 address   IPv4 address that is used for configuration and access to the system.
Gateway IPv4 address   IPv4 address for the default local gateway for the system.
IPv4 subnet mask   IPv4 subnet mask, which identifies the IPv4 network on which the system is operating.
Management IPv6 address   IPv6 address that is used for configuration and access to the system.
Gateway IPv6 address   IPv6 address for the default local gateway for the system.
IPv6 prefix   The system prefix, which identifies the IPv6 network on which the system is operating.
Port 2 (optional)
Management IPv4 address   IPv4 address that is used for configuration and access to the system.
Gateway IPv4 address   IPv4 address for the default local gateway for the system.
IPv4 subnet mask   IPv4 subnet mask, which identifies the IPv4 network on which the system is operating.
Management IPv6 address   IPv6 address that is used for configuration and access to the system.
Gateway IPv6 address   IPv6 address for the default local gateway for the system
IPv6 prefix   The system prefix, which identifies the IPv6 network on which the system is operating.
Use Table 2 to plan the service addresses required to conduct service actions on individual node canisters.
Important: The management and service addresses for the system and its node canisters must be allocated within the same network.
