When you telnet to an MP, you will initially access the console of the associated server. Other options su as remote console access, power management, remote re-boot operations, and temperature monitoring are available by typing control-B from the console mode. It is also possible to access the MP as a web consol However, before it is possible to access the MP remotely it is first necessary to assign an IP address to ea MP. This is normally achieved by connecting a serial console device to the serial port on the MP and performing a series of configuration steps. This can be quite tedious and time consuming for moderate to large clusters. To ease the effort, mp_register can perform the configuration for you by issuing the commands via a serial cable. mp_register maintains a database of knowledge about the MP cards in the system. The database is restrict to nodes that have been added to the cluster with manager_config. Likewise, nodes removed from the clu are removed from the MP database. The utility is generally designed for single use when setting up the cluster for the first time. However, it can be run multiple times to make changes to MP designations or w nodes are added to the cluster. Note: It is important to note that the configuration step does not configure accounts for the MP. By default, anyone can access the MP without a password. Leaving the cards without configured users is a severe security risk. Users can freely access the card and shut down the node or gain root access through the console. The configuration step configures the MP for telnet or web access only to make future modifications, such as adding users simpler to perform. mp_register will add each MP and associated IP address to the /etc/hosts file on the Management Server. This file will later get propagated to the Compute Nodes. Each MP is assigned a name during the configuration step which is also placed in the /etc/hosts file. This name is derived as the name of the associated host appended with '-mp' (for Management Processor). For example, the MP associated with th host foo will be named foo-mp. Overview Provide the following information to the mp_register program about each MP card that is connected to a Compute Node. It will configure all MPs automatically, instead of requiring you to manually connect the to a serial console device. z IP address, z Netmask, z Gateway IP address. Details For each node, the program will ask you if you want to establish an MP for that machine. It will also ask the MP is already configured. If it is not already configured, you will be prompted to connect a serial cab from the serial port of the Management Server to the serial port of the MP to be configured. The program will then use the information you entered about the card to configure it. Each MP can be configured in tu MPs which have been previously configured can be added to the database without being configured. Before invoking mp_register to initially configure the MP cards on each Compute Node, obtain a serial c long enough to connect from the serial console port on the back of the Management Server to the serial
