| Preconfigured TCP/IP addresses for 10/100/1000 Ethernet |
| |||
Each connection should be to a different 10/100/1000 Ethernet switch, which are elements of the customer’s network. The reason to use different switches is to enhance network availability to the DR550. The boot network is the network for normal usage. The second network is the standby network which is used in case of problems with the boot network.
It is important not to change the TCP/IP addresses on the P5 520 servers for the attachment of the DS4100 servers nor change the TCP/IP addresses on the DS4100 storage servers.
HACMP Configuration
When changing the IP addresses, you should use the integrated console to make these changes. If the integrated console is not working, the serial port on the front of each P5 520 server is available for connection to a TTY terminal (provided by the customer). The console works best with a physical ASCII terminal such as IBM 3151 or vt100 or a PC workstation running a terminal emulator such as hyperterm, emulating vt100.
HACMP heartbeat information is exchanged between the two nodes through the host bus adapters (Ethernet) in slot 3 of the P5 520s. This connection is used to monitor the network and server, ensuring that a failure does not cause an interruption in data access.
The HACMP configuration needs to be modified when the solution is deployed in the customer environment. The boot and the standby addresses will have to be modified to be compatible with the customer subnet that they connect to. It is a best practice recommendation to have them (boot and standby) on different subnets.
Procedures for Changing IP Addresses
To configure the DR550 for the use with your network you have to change five IP addresses from their factory settings. The changes are made on both P5 520 servers. No changes are needed on the DS4100 or the
The following table, which was also provided in the Site Preparation and Planning Section of this document, may be helpful in recording the IP addresses to be used in your operational environment.
