IBM Knowledge Center - lsuser Command. 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. Learn the files first, then the commands Before going into the commands to create, modify, and maintain users and groups in AIX, it is important that you know what is happening behind the scenes.

Trucos y atajos para UNIX. Tratamiento masivo de datos con AWK, alternativa parcial a ACL o SAS.
GNU awk es una herramienta muy útil para modificar archivos, buscar y transformar datos y, en general, realizar cualquier tipo de tratamiento masivo de ficheros. Con un programa awk es posible contar el número de líneas de un archivo, seleccionar columnas, aplicar filtros, realizar cruces, borrar el último campo de cada línea, hacer sumarizaciones, comprobar duplicados, muestreos, etc. Para aprender a utilizar AWK mediante esta pequeña guía, lo mejor es copiar los ficheros de ejemplo que aparecen y ejecutar las instrucciones o programas que se comentan para ver directamente cual es el resultado.

How to Resolve Duplicate PVID on Clariion Disk (SAN) in AIX? - Toolbox for IT Groups. We have an AIX 6.1 box which has a Clariion SAN Disk attached to it.
We wanted to 'present' the disk to its cloned server but we're having problems while doing the process. WHenever we try to command cfgmgr, there would always be a duplicated PVID. AIX Commands Support Tips. Ac Displays connect time totals for users Example: ac root Outputs: total 52.80 seconds at Schedules jobs to run at a later date basename Returns the base file name of a string Example: echo `basename \`pwd\`` Returns the name of the current directory your in.
Batch. AIX File Structure Volume Logical Tips. Definitions Logical Volume Set-up All system LVs (hd1..hd8, hd9var) should reside in the VG named rootvg, under one PV if possible. This will allow complete re-installation of the system from your 'mksysb' tape without affecting the application data that resides on your other VGs. There is no difference in response time between a single or multiple VGs.
When an LV is accessed The ODM database (/etc/objrepos/*) is searched to determine which VG the LV belongs to. A few notes about Mirroring Mirrored LVs that generate lots of write I/O calls, will cause a disk performance penalty (such as paging LVs). IBM Knowledge Center. Cannot extend vg - but why ?

How do the properties and WWPN/WWNN of a virtual fibre channel adapter on AIX 6.1 with VIOS 2.1 using NPIV look like? - AIX & System P Community. Virtualization is a key factor of IBM's Smarter Planet - Dynamic Infrastructure strategy. On System p the Virtual I/O Server (VIOS) allows sharing of physical resources between LPARs including virtual SCSI, virtual Fibre Channel (NPIV) and virtual networking. N_Port ID Virtualization(NPIV) is a standardized method for virtualizing a fibre channel port. An NPIV-capable fibre channel HBA can have multiple N_Port IDs, each with a unique identity and world wide port name. Here I provide an example of how the virtual fibre channel adapter attributes with NPIV and their associated world wide node name (WWNN) and world wide port name (WWPN) look like using the Virtual I/O Server with the 8Gbps Fibre Channel HBA #5735. The examples are given using AIX 6.1 TL4 SP2 as VIOC with VIOS 18.104.22.168 FP22.1 and a B64 SAN switch.
