S1000-007 Exam Dumps : IBM AIX v7 Administrator Specialty

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

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
