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.

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.
考题
Using splitvg to create a snapshot volume group of rootvg results in an error. What is the most likely cause of the error（）A、There is not an available disk to allocate to the snapshot volume groupB、One of the physical volumes associated with rootvg has a status of "missing"C、Rootvg is running in enhanced concurrent modeD、A snapshot volume group cannot be created for the rootvg
考题
A system administrator has backed up the datavg volume group using the savevg command. There are several raw logical volumes and some unmounted jfs filesystems in datavg. Which of the following statements is true about this backup?（）A、The volume group and all logical volumes will be recreated. All raw and jfs filesystms will be backed up and restored.B、This backup will be bootable and the volume group and all jfs logical volumes will be recreated.C、This backup will not be bootable and the restorevg command is used to restore only the mounted and non-raw logical volumes. It will not recreate any logical volumes that are raw or unmounted.D、The volume group and all logical volumes information is archived and will be recreated. The raw and unmounted filesystems will not be backed up and therefore not restored.
