mmstartup Command Name mmstartup – Starts the GPFS subsystem on one or more nodes. Synopsis mmstartup [-a | -N {Node[,Node...] | NodeFile | NodeClass}] [-E EnvVarString] Description Use the mmstartup command to start the GPFS daemons on one or more nodes. If no operand is specified, GPFS is started only on the node from which the command was issued. Results Upon successful completion of the mmstartup command, the GPFS subsystem is started on the specified nodes. Note: The actual start of the GPFS daemons on the nodes also depends on: v The availability of all required software for your environment v The availability of required hardware for your environment v Quorum requirements For the actual requirements for your operating environment, see the General Parallel File System: Concepts, Planning, and Installation Guide and search for installing GPFS. Parameters -a Start GPFS on all nodes in a GPFS cluster. -N {Node[,Node...] | NodeFile | NodeClass} Directs the mmstartup command to process a set of nodes. For general information on how to specify node names, see “Specifying nodes as input to GPFS commands” on page 4. Options This command does not support a NodeClass of mount. -E EnvVarString Blank-separated string that specifies the name and value (name=value) for one or more environment variables to be passed to the GPFS daemon. Enclose this string in quotes. Exit status 0 Successful completion. nonzero A failure has occurred. Security You must have root authority to run the mmstartup command. You may issue the mmstartup command from any node in the GPFS cluster. When using the rcp and rsh commands for remote communication, a properly configured .rhosts file must exist in the root user’s home directory on each node in the GPFS cluster. If you have designated the use of a different remote communication program on either the mmcrcluster or the mmchcluster command, you must ensure: 270 GPFS: Administration and Programming Reference
1. Proper authorization is granted to all nodes in the GPFS cluster. 2. The nodes in the GPFS cluster can communicate without the use of a password, and without any extraneous messages. Examples To start GPFS on all nodes in the GPFS cluster, issue this command: mmstartup -a The system displays information similar to: Thu Aug 12 13:22:40 EDT 2004: 6027-1642 mmstartup: Starting GPFS ...
