Thelsfscommand in AIX gets its information from the/etc/filesystemsfile. This file contains definitions of all file systems and their attributes, including mount points, device names, and mount options. Thelsfscommand reads this information to display details about the file systems on the system.References:= 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

Thelparstat -icommand provides detailed information about the logical partition, including whether it is using shared or dedicated processor resources. This command displays the partition's configuration, processor mode, and other relevant details that help the administrator determine the resource-sharing status.References:= IBM AIX Documentation

Mirror pools in AIX allow administrators to define specific sets of disks that can be used for mirroring logical volumes. This feature provides greater control over the allocation of mirror copies, ensuring that each copy is placed on separate, specified disks to improve data redundancy and reliability. This setup helps in managing disk utilization and performance more efficiently. The other options do not accurately describe the primary benefit of mirror pools.References:= IBM AIX Documentation

Thevtmenucommand in an HMC SSH session is used to display a menu of all managed systems and their LPARs. This menu provides options to open virtual terminal sessions to these LPARs, making it easy for administrators to monitor the boot process and manage their AIX partitions. Other commands likemkvtermopen a console for a specific partition, butvtmenuis designed to list all and provide an interface for selection.References: IBM HMC Documentation

The root account is the special user in the /etc/passwd file with the user ID (UID) of 0 and is commonly given the user name, root. It is not the user name that makes the root account so special, but the UID value of 0. This means that any user that has a UID of 0 also has the same privileges as the root user. Also, the root account is always authenticated by means of the local security files.

In AIX, console log messages are recorded using thealogcommand. Thealogutility manages log files, including the console log, which captures system messages and output sent to the console. This utility provides a means to view and manage these logs for diagnostic and auditing purposes.References: IBM AIX Documentation – alog

The cfgmgr command updates the system configuration database with the current configuration of the devices attached to the system. When the SAN administrator increases the size of a LUN device (hdisk), it is not automatically reflected on the AIX LPAR. Running the cfgmgr command updates the system with the new size information and makes it visible to the system administrator.

Devices that are connected to the system can be in one of four states.

Devices that are connected to the system can be in one of the following states:

Item

Description

Undefined

The device is unknown to the system.

Defined

Specific information about the device is recorded in the customized database, but it is unavailable to the system.

Available

A defined device is coupled to the operating system, or the defined device is configured.

Stopped

The device is unavailable but remains known by its device driver.

If a tty device and a printer alternately use the same tty connector, both a tty device and a printer are defined on the same parent and port in the device configuration database. Only one of these devices can be configured at a time. When the tty connector is configured, the printer specific setup information is retained until it isconfigured again. The device is not removed; it is in the defined state. Maintaining a device in defined state retains customized information for a device that is not currently in use, either before it is first made available or while it is temporarily removed from the system.

If a device driver exists for a device, the device can be made available through the device driver.

In AIX, when creating a new user account without specifying a group, the default group assigned isstaff. This is a predefined group in AIX systems that is typically used for regular user accounts. It provides basic permissions and access suitable for non-administrative users.References: IBM AIX Documentation - User Management
