The logical volumedatalvhas 30 Logical Partitions (LPs), each of 1024 megabytes (MB), or 1 gigabyte (GB). Therefore, the total usable size of the logical volume is 30 LPs * 1 GB per LP = 30 GB.References:= IBM AIX Documentation
Question 2
What is the effect of running the mount -a command?
Options:
A.
All JFS/JFS2 file systems are mounted.
B.
All automatic file systems are mounted.
C.
All file systems set to mount=true are mounted.
D.
All file systems defined to the system are mounted
Answer:
C
Explanation:
Themount -acommand in AIX mounts all file systems that are specified in the/etc/filesystemsfile and have the attributemount=true. This ensures that only those file systems that are configured to be automatically mounted are actually mounted when this command is executed. It does not mount all defined file systems, only those marked for automatic mounting.References: IBM AIX Documentation – mount
Question 3
Which two elements of an hdisk are read by the importvg command to identify volume group members?
Options:
A.
LVID - Logical Volume ID
B.
UUID - Universally Unique ID
C.
UDID - Unique Device ID
D.
VGDA- Volume Group Descriptor Area
E.
PVID - Physical Volume ID
Answer:
D, E
Explanation:
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
