IBM AIX v7 Administrator Specialty S1000-007 Full Course Free

Theimportvgcommand in AIX reads the Volume Group Descriptor Area (VGDA) and the Physical Volume ID (PVID) of the disks to identify and import volume group members. The VGDA contains metadata about the volume group, including information about logical volumes and physical volumes. The PVID is a unique identifier assigned to each physical volume, helping the system recognize and manage the disks within a volume group. The other elements, such as LVID, UUID, and UDID, are not used by theimportvgcommand for this purpose.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

To unconfigure a device and remove its definition from the Customized Devices object class in AIX, the commandrmdev -dl rmtOis used. The-doption indicates the removal of the device definition, and the-loption specifies the logical name of the device. This command ensures that both the device configuration and its definition are deleted from the system.References:= IBM AIX Documentation
