  The purpose of this readme is for providing some background to the technologies, so it will put some context to the How-to articles. What are LPARs? LPARs - Logical Partitions, LPARs are a way of dividing up POWER (chip) servers or blades to look like they are one or more servers. Processors, memory and I/O can be split into logical partitions. If these resources are allocated only to one partition it called a Dedicated LPAR. What are DLPARs? DLPARs - Dynamic LPARs, DLPARs are similar to LPARs, but allow for resources to be dynamically added or removed from a partition. How are LPARs/DLPARs managed? To someone new to AIX, confusingly in a many ways. Primarily using the so called Hardware Management Console (HMC), On top of this there many ways to setup a HMC. What is the Hardware Management Console? As per the name, it manages & configures all hardware across several POWER based systems. As of POWER7 there is a web based GUI access to the HMC. You can have two HMC's in a HA config. New to HMC's version 8, is the vHMC, a virtualised HMC. The default HMC login is hscroot with password abc123, and the root user password is passw0rd.

  Use these commands with caution. As always rebooting, reseting, restarting, shutting down, stopping, powering off, all should be done with great caution, with consideration to applications running. This may sound basic knowledge, but in the world of virtualization it is often thought it does not matter so much if users are not logged or the server is for testing only, don't matter, still use the proper commands when doing any of these tasks. A soft reset of LPAR hscroot@hmc8> chsysstate -r lpar -m pserver1 -o shutdown -n mylpar1 A hard reset of LPAR (swipe the carpet from under it's feet, last resort!) hscroot@hmc8> chsysstate -m pserver1 -r lpar -n mylpar1 -o off

  LPARs are mainly created on the HMC using the GUI, because there are many settings which are visually easier to see, but as always the CLI can speed things up. To list the current lpars hscroot@hmc8> lssyscfg -m pserver1 -r lpar -F name mylpar1 Create a new lpar hscroot@hmc8> mksyscfg -m pserver1 -r lpar -i "name=apache_test,lpar_env=aixlinux,profile_name=norm, min_mem=1024,desired_mem=1024,max_mem=1024, proc_mode=shared,sharing_mode=uncap,uncap_weight=128, min_proc_units=0.1,desired_proc_units=0.4,max_proc_units=2.0, min_procs=1,desired_procs=2,max_procs=4,lpar_io_pool_ids=none, max_virtual_slots=10,auto_start=0,boot_mode=norm, power_ctrl_lpar_ids=none,conn_monitoring=0, virtual_eth_adapters=3/1/1//0/1,virtual_scsi_adapters=3/client/1//10/1" Another listing of the lpars hscroot@hmc8> lssyscfg -m pserver1 -r lpar -F name mylpar1 apache_test Another way is put all the parameters in a file and call the file using the mksyscfg command and instead of using -i use -f option to read parameters from a file hscroot@hmc8> mksyscfg -m pserver1 -r lpar -f ./my_lpar_file
