LVM was designed to
A. handle disks up to 9Gb
B. allow more than one file system on a single disk
C. increase system performance
D. allow greater flexibility in the management of disks

A volume group is
A. a collection of physical volumes grouped together to hold information
associated with an application
B. a collection of physical volumes grouped together to hold a file system
C. the structure used to hold boot information
D. a collection of whole disks or sectioned discs

Possible examples of a pvcreate command would be
A. pvcreate -B /dev/rdsk/c0t0d0
B. none of these
C. pvcreate -B /dev/dsk/c0t1d0
D. pvcreate -F vxfs /dev/dsk/c0t1d0
@ a @ pvcreate command must be used with raw disk device file. That is the main
point.

What command would you use to check the physical extent size that will be
used when you create logical volumes from the volume group \"vgmyvol\"?
A. vgshow /dev/vgmyvol
B. pvdisplay /dev/vgmyvol
C. lvdisplay /dev/vgmyvol
D. vgdisplay /dev/vgmyvol
@ d @
The correct answer is: D. vgdisplay /dev/vgmyvol
The vgdisplay command reports : \" PE Size (Mbytes)\" .

Besides the standard ioscan command, another command that could be used
to identify which hardware address \"goes with\" which device
file is:
A. lssf
B. listsf
C. lsspecial
D. displaysf
@ a @
The correct answer is: A. lssf List Special File (lssf) determines the major
number of the special file and whether it is bloc or character. It then
scans the system for the device that is associated with the special file.
When the device is found, the minor number of the special file is also
decoded. A mnemonic description of the minor numer is printed on standard
output along with the hardware path of the device.

The main internal structures of a JFS file system are
A. superblock, cylinder groups and inodes
B. allocation units and cylinder groups
C. intent log, cylinder group and inodes
D. superblock, intent log and allocation units

The newfs command is used to create:
A. HFS file systems only.
B. CDFS file systems.
C. a mirror copy of an existing file system.
D. HFS and JFS file systems.
@ d @
The correct answer is: D. HFS and JFS file systems.
The newfs command is a \"friendly\" front-end to the mkfs command. It
calculates the appropriate parameters and then builds the file system by
invoking mkfs. It is capable of creating all supported types of local file
systems.

The file that contains the default file system type for file system creation
is:
A. /etc/fstab
B. /etc/filesystem
C. /etc/default/fs
D. /var/adm/sbtab
@ c @
The correct answer is: C. /etc/default/fs
The directory \"/etc/defaults\" contains various plain text files in which
default values are stored for some system services and utilities. The
file\"/etc/defaults/fs\" is used by the various file system creation
routines if a file system type is not explicitly stated on the command
line.The directory \"/etc/defaults\" contains various plain text files in
which default values are stored for some system services and utilities.
The file\"/etc/defaults/fs\" is used by the various file system creation
routines if a file system type is not explicitly stated on the command line.

The command lsdev is used to show block and character:
A. minor numbers for all drivers configured into the kernel.
B. major numbers for all drivers.
C. major numbers for all drivers configured into the kernel.
D. major numbers for all drivers currently in use by system peripherals.
@ c @
The correct answer is: C. major numbers for all drivers configured into
the kernel.
The lsdev command list the major device numbers, the name of the associated
driver and the class designation for all drivers/pseudo-drivers cinfigured
into the kernel and available for invocation via \"special files\".

A logical extent is the
A. smaller than a physical extent
B. the smallest amount of space addressed by one disk access
C. smallest amount of space allocated to a logical volume
D. is always 4 Mb in size
@ c @
remember?

To place a logical volume on a specific disk you do the following
A. use lvcreate with no size option and use lvextend to specify the disk
and size
B. specify the physical volume on the end of the lvcreate
C. use SAM
D. use lvmove
@ a @ It is a tip.

The program that runs automatically at the end of an install to establish
the system date, hostname, and IP address is:
A. /sbin/set_parms
B. /etc/hosts
C. /sbin/date
D. /sbin/setboot
@ a @
The correct answer is: A. /sbin/set_parms
This script was originally designed to help the administrator bring a
system up after a fresh load. It’s primary goal was to set some local
configurables and attach the system to the LAN and initialize the settings
for common network services (such as DNS, NIS, ....).

command could you run, without rebooting the system, to create the device
files?
A. mkcd -a
B. insf -e
C. lssf -e
D. cdfs -a
@ b @
The correct answer is: B. insf -e

directory (the -e option reinstalls missing special files for existing
devices).

You want to create a new 200MB logical volume from the volume group vg00,
using the default physical extent size. Instead of taking
the default logical volume name, you want to name your logical volume
\"newlv\". What command would you use?
A. lvcreate -l 200 -n newlv /dev/vg00
B. lvcreate -L 200 /dev/vg00/newlv
C. lvcreate -l 200 -n /dev/vg00/newlv
D. lvcreate -L 200 -n newlv /dev/vg00
@ d @
D. The \"-L\" option specifies MBs the \"-n\" option indicates a user defined
logical volume name instead of the default. The last argument is
the volume group in which the logical volume will be created.
