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 jfslog
• B、Use the chlv command to change the lv type of /dev/fs1log to jfslog
• C、Use the chvg command to change the default jfslog of testvg to /dev/fs1log
• D、Edit the /etc/filesystems file to change the log associated with /test/fs1 to /dev/fs1log

Using the C-SPOC utilities， an administrator has created a new volume group and filesytems. Theadministrator performs an Isvg -I command on the volume group and notices that the log logical volume created in C-SPOC is closed/syncd and loglv01 has been created and is in use.  What step was required in order for the logfile created by C-SPOC to be used.（）  

• A、 Perform the C-SPOC logform utility option prior to creating any filesystems.
• B、 Manually perform a logform outside of C-SPOC prior to creating any filesystems.
• C、 Run a logredo command and select log logical volume created in C-SPOC as the preferred jfslog.
• D、 Use C-SPOC to delete and recreate the log logical volume，set the perform logform option to true.

While attempting to expand a file system, an administrator receives an error message indicating that the filesystem is not recognized. Running the 'lsfs' command fails to display any output, but the 'df' command is working and displays normal filesystems. What is the likely cause of the problem?（）

• A、The /etc/filesystems file is missing.
• B、The /dev/hd8 logical volume is corrupt.
• C、The hosting volume group is not varied on.
• D、The /var and /tmp filesystems may be full.

第5题：

A log logical volume is created as indicated below: root@host1:/# mklv -a c -t jfs2log -b y datavg 1 loglv00 root@host1:/# lsvg -l datavg datavg: LV NAMETYPELPsPPsPVsLV STATE MOUNT POINT loglv00jfs2log111closed/syncdN/AA new filesytem is then created using the new log logical volume.When the administrator attempts to mount the filesytem, the following error occurs:root@host1:/# mount/newfs mount: 0506-324 Cannot mount /dev/lv00 on /newfs: Asystem call received a parameter that is not valid. Which of the following actions will resolve this error?（）

• A、Recreate the file system with -p rw flags and re-mount.
• B、Run 'logform /dev/loglv00' and hit 'y' to destroy all data.
• C、Run 'clrginfo -p' to clear the invalid filesystem parameter.
• D、Change 'account = true' value in /etc/filesystem to 'account = false'.

During an attempt to mount filesystems on the datavg volume grou, the following error message occurs: "0506-323 Cannot get information about log device loglv00." The error is due to the fjslog used by these filesystems is located on a bad disk.Which of the following procedures should be performed to fix the error?（）

• A、Run fsck on all filesystems using loglv00
• B、Run the logform command against loglv00
• C、Recreate the filesystems and restore from a backup
• D、Create a new jfslog and change /etc/filesystems to point to this log

第7题：

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.
