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.

The system administrator wants to use a new jfslog /dev/fs1log with the filesystem /test/fs1 on the testvg volume group. The following commands were used to create the log and assign it to the filesystem： （1）mklv -t jfslog -y /dev/fs1log testvg 1 （2）chfs -a log=/dev/fs1log /test/fs1 While trying to mount the /test/fs1 filesystem the administrator received the error： "Cannot mount /dev/fs1lv on /test/fs1： A system call received a parameter that is not valid". What step did the administrator miss that most likely caused the error？（）A、Use the logform command to format /dev/fs1log as a jfslogB、Use the chlv command to change the lv type of /dev/fs1log to jfslogC、Use the chvg command to change the default jfslog of testvg to /dev/fs1logD、Edit the /etc/filesystems file to change the log associated with /test/fs1 to /dev/fs1log

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.
