The System Resource Controller (SRC) is the main process that starts other background processes when the system boots. It is started through the /etc/rc.srcmstr script which is run by the init process. This script reads the /etc/inittab file and starts the necessary processes. Reference: IBM AIX v7 Administrator Specialty Study Guide.

The System Resource Controller (SRC) in AIX is started by the script/etc/rc.srcmstr. This script initializes and starts the SRC daemon (srcmstr), which manages subsystems, subsystem groups, and subsystem processes. It is a critical part of the AIX startup process, ensuring that necessary systemservices are properly managed.References: IBM AIX Documentation - System Resource Controller

Theprintqaccount is associated with printing capabilities in AIX. If the new system does not require any printing capabilities, theprintqaccount can be safely removed from the system.References:= IBM AIX User Account Management Documentation

To create a file system with specific attributes such as logical volume name, disk location, and disk placement, the administrator should first use themklvcommand to create the logical volume with the desired properties. Then, thecrfscommand is used to create the file system on that logical volume. This pair of commands allows the administrator to set the required attributes during the creation process.References:= IBM AIX Documentation, IBM AIX Documentation

In the/etc/filesystemsfile, theautoattribute can be set tonoto prevent the automatic mounting of NFS filesystems during system startup. This ensures that the system does not attempt to mount NFS filesystems, thereby avoiding potential hangs during network outages.References:= IBM AIX Documentation

Therpmcommand is used to install, update, and manage packages from the AIX Toolbox for Linux Applications. This toolbox provides GNU and open source tools for AIX, and therpmcommand handles the package management of these tools.References:= IBM AIX Toolbox for Linux Applications

The command used to monitor SAN I/O performance/throughput is iostat -DIRT 60 10. The iostat command is used to monitor I/O performance and throughput on a SAN device. The DIRT (Disk I/O Response Time) flag can be used to display the response time for each I/O request. The last two arguments, 60 and 10, are the interval (in seconds) and the number of iterations respectively. This command will monitor I/O performance/throughput every 60 seconds for 10 iterations.

 Theyumtool can be used to simplify the installation of RPM packages by automatically resolving and installing prerequisite dependencies.yumis a package manager that handles the retrieval and installation of packages from repositories, making it easier to manage dependencies compared to manually using therpmcommand.References: IBM AIX Documentation – yum

According to the IBM AIX v7 Administrator Specialty Study Guide, the lsmcode command is used to list the microcode of the system. The -A flag is used to list the microcode level and the active microcode level of the system. This command can be used to confirm the system firmware level which is required to use the IBM Fix Level Recommendation Tool (FLRT).

When a user logs in, the system will process their .profile file which contains the PATH variable. This variable specifies the list of directories that the system will search through to locate executable files. If the PATH variable contains non-existent directories, then it will take longer for the system to process the .profile file, resulting in a slower login experience.

The superstrict mirror write consistency policy is the most reliable policy for achieving data consistency between mirrors in AIX V7.2. This policy will maintain the data consistency between mirrors by writing the data to both mirrors before the write operation is acknowledged as complete.
