000-221 Question #100: Real Exam Question with Answer & Explanation
The correct answer is C. Have all applications shut down.. When cloning a data volume group to a new system, all applications must be shut down first to guarantee a consistent backup image before migration.
Question
A P0WER5 520 system is being cloned onto a Power 780. The source system is on internal disks, and the vg01 volume group is mirrored. After installing AIX, which sequence of actions will recreate the vg01 volume group and restore data on the new system?
Options
- AHave all the applications shut down.
- BCreate a backup onto an NFS server using the mksysb command and referencing the correct data
- CHave all applications shut down.
- DShut down all application running from the data volume group.
Explanation
When cloning a data volume group to a new system, all applications must be shut down first to guarantee a consistent backup image before migration.
Common mistakes.
- A. This option describes a generic shutdown of all applications system-wide rather than targeting the sequence of steps specific to safely cloning a data volume group, making it a less precise and incomplete procedure.
- B. mksysb is designed exclusively for backing up the root volume group (rootvg) and cannot be used to back up a data volume group like vg01 - savevg is the correct command for non-rootvg volume groups.
- D. Shutting down only applications visibly running from the data volume group may miss background daemons or processes with open file handles on vg01, leaving the risk of an inconsistent backup image.
Concept tested. AIX data volume group backup sequence using savevg
