You have taken a Logical Volume Manager (LVM) snapshot backup of a volume that contains the MySQL data directory. Why is it important to remove snapshots after completing a RAW backup in this way?() A.The snapshot size will continue to grow as changes to the volume are madeB.The snapshots take a significant amount of disk space as they are a duplicate copy of the dataC.The system can only support one snapshot per volume, and you need to remove it to be able to take your next backupD.The system keeps a copy of changes in memory and can cause an out of memory event
Which command synchronizes or rebuilds the logical volume control block, the device configuration database, and the volume group descriptor areas on the physical volumes?() A.syncvg rootvgB.synclvm rootvgC.varyonvg rootvgD.synclvodm rootvg
A booting system appears to be hanging with an LED code of 0c54. What is the likely cause?() A.An AIX install is in progress.B.The rootvg volume group is corrupt.C.The TCPIP configuration is incorrect.D.At least one paging device cannot be varied on.
The ‘lsvg －o‘ command is run with an output of only rootvg, but the server has another volume group named datavg, which is notdisplayed.What is the likely cause?() A.datavg is in an offline state.B.‘lsvg -o‘ only displays the root volume group.C.‘lsvg -o‘ only displays the fist volume group.D.datavg has no filesystems and therefore, is inactive.
The system administrator notices that there is an I/O bottleneck on one of three disks in datavg volume group. This problem disk contains the JFS log， loglv00 and one filesystem， /mydatabase. There are no other logical volumes on this disk. Which of the following options would be the best solution？（）A、 Increase the size of the JFS log logical volume so more transacations can be written to this log.B、 Create a second， additional JFS log and have the /mydatabase logical volume point to both JFS logs.C、 Migrate the JFS log device to another physical disk in the same volume group.D、 Only one JFS log device for each volume group can be used. Use the migratepv command to move the JFS log device to an empty disk in another volume group.
A previously functional， scheduled snapshot operation against a JFS2 filesystem has failed. The JFS2 filesystem is mounted and appears intact. What is the most likely cause of the failure and how should it be resolved？（） A、The associated JFS2 log device has failed. Check the log device and varyon the device.B、The logical volume that hosts the snapshots is full. Increase the size of the logical volume.C、Fifteen snapshots already exist for the given JFS2 filesystem. Delete at least one existingsnapshot.D、The volume group that hosts both the snapshots and JFS2 filesystem has lost quorum. Check and correct the integrity of the volume group.

The 'lsvg -o' command is run with an output of only rootvg, but the server has another volume group named datavg, which is notdisplayed. What is the likely cause?（）A、datavg is in an offline state.B、'lsvg -o' only displays the root volume group.C、'lsvg -o' only displays the fist volume group.D、datavg has no filesystems and therefore, is inactive.
A client partition has the rootvg disks mapped from two separate VIO servers. They are using AIX mirroring to provide redundancy on rootvg. One of the VIO servers was taken down for maintenance and is now back on-line. The client partitions now show Physical Partition Marked Stale in the errpt. Which of the following will most likely resolve the problem？（）A、Run cfgmgr to re-scan the devices.B、Run mkvdev on the VIO server to re-create the devices and re-mirror rootvg.C、Run varyonvg rootvg to refresh the volume group.D、Run syncvg on the rootvg to synchronize rootvg.
Which command synchronizes or rebuilds the logical volume control block， the device configuration database， and the volume group descriptor areas on the physical volumes？（）A、syncvg rootvgB、synclvm rootvgC、varyonvg rootvgD、synclvodm rootvg
An administrator is trying to extend an existing volume group with a new hard disk, but the extendvg command returns the following error. 0516-1162 /usr/sbin/extendvg. Warning, The Physical Partition Size of 64 requires the creation of 8924 partitions for hdisk11. The limitation for volume group datavg is 1016 physical partitions per physical volume. Use chvg command with -t option to attempt to change the maximum Physical Partitions per Physical volume for this volume group. The chvg -t may or may not allow the extendvg command to succeed. What is the implication of using this option?（）A、It reduces the maximum file size allowed within the given volume group.B、It reduces the maximum number of files allowed within the given volume group.C、It reduces the maximum number of logical volumes allowed within the given volume group.D、It reduces the maximum number of physical volumes allowed within the given volume group.
One of the mirrored disks for the root volume group has failed. Although the logical volumes are mirrored, and the bosboot command was run, the machine will not boot. What is the most probable cause?（）A、Quorum was not turned offB、Paging space was not mirroredC、The dump space was not mirroredD、The surviving disk was too small

Error log analysis indicates that a disk is starting to fail and will need to be replaced. The failing disk contains multiple logical volumes which span multiple disks. A free disk has been added to the failing disk’s volume group.Which of the following is the most efficient method to move the data from the failing disk to the new disk？（）A、Back up the data， remove the failing disk from the volume group， then restore the data to the new disk.B、Use the migratepv command to move data from one disk to another and then remove the failing disk from the volume group.C、Use the mirrorvg command to mirror the data to the new disk， break the mirror and then remove the failing disk from the volume group.D、Create a new filesystem on the new disk and use the mv command to move the data to the new filesystem， and then remove the failing disk from the volume group.
