Defining a new Network Install Interface on a NIM master. (Chris's AIX Blog) OK, so I had a NIM master with two network interfaces, en0 and en1.

Defining a new Network Install Interface on a NIM master. (Chris's AIX Blog)

The en0 interface was connected to the network and the en1 interface was connected to the network. When the master was initially configured, we chose en0 as the primary install interface. The master could now install NIM clients on the network, without any additional NIM network configuration. root@nim1 / # ifconfig –a en0: flags=1e080863,480<UP,BROADCAST,NOTRAILERS,RUNNING,SIMPLEX,MULTICAST,GROUPRT,64BIT,CHECKSUM_OFFLOAD(ACTIVE),CHAIN> inet netmask 0xffffff00 broadcast AIX for System Administrators: ODM. It is a database of system and device configuration information integrated into the OS.

AIX for System Administrators: ODM

It is intended for storing system informations: software infos (smit menus and commands, installed filesets...) and device infos (device configurations, tcp/ip configs...) For safety reasons the ODM data is stored in binary format. All ODM commands use the ODMDIR environment variable, that is set in file /etc/environment. The default value of ODMDIR is /etc/objrepos. AIX ODM Commands - UnixMantra. ODM is object database Manager Use these commands with EXTREME CAUTION!!!

The fundamental concept used by lvm are1.physical volume2.volume group3. physical partition4.logical volume5.logical partitions6. filesystems7. raw devices each individual disk drive is named as physical volume such as hdisk0,hdisk1. one or more pv's can make up a volume group(VG). a pv can belong to maximum of one vg you can't assign a fraction of pv to one VG physical volumes can be assigned to the same VG even though they are of different type such as SCSI or SSA.


The storage space from physical volume is divided into physical partitions(PP's) the size of PP's are identical on all disks belonging to the same VG. Aix system admin: LOGICAL VOLUME MANAGEMENT.

AIX user and group administration. Adam CormanyPublished on September 15, 2009 Administering users and groups in IBM AIX is an essential part of an administrator's duties. You can manage users and groups in many different ways: You can maintain them through the AIX System Management Interface Tool (SMIT), manually editing the configuration files, or by using command-line commands. This article discusses the configuration files behind users and groups on AIX, as well as command-line tools designed to help manage the users and groups easily.
