To resolve the issue with the power supply, the administrator should rundiagwith the option to log the repair action. This command will allow the system to acknowledge the hardware replacement and update the hardware error log, thus preventing further false reports regarding the power supply problem.References:= IBM AIX Diagnostic Documentation

Thevmstat -scommand in AIX displays various system statistics since the last reboot, including the cumulative count of paging space page outs and free frame waits. This command provides detailed system performance information, which helps in diagnosing memory and paging issues. Other commands listed, such asps guw,svmon -G, andioo -L, do not provide cumulative counts of these specific metrics.References:= IBM AIX Documentation

If an administrator does not receive a console login prompt after booting a system, two potential reasons could be:

Inittab entries before the console login have not completed running. The/etc/inittabfile controls the initialization process, and if prior entries are hanging or taking a long time to complete, it can prevent the console login from appearing.

There is no console entry in the/etc/inittab. The absence of a console entry means the system does not know to start a console login process, which would prevent the login prompt from appearing. Other reasons like full file systems, rezoned disks, or overwritten rootvg could cause system issues but would not specifically prevent the console login prompt from appearing if the system is running.References:= IBM AIX Documentation

In AIX, error entries related to a system crash are preserved by writing them to Non-Volatile Random Access Memory (NVRAM). These entries are processed and logged to the system error log when the system comes back up. This ensures that critical error information is not lost during a system crash.References:= IBM AIX Documentation
