La commande 'mkszfile' permet de recréer le fichier de description du groupe de volume 'rootvg'.
Il suffit de lancer la commande sous le compte 'root' pour créer le fichier /image.data contenant toutes les informations de structure du VG.
Exemple :
# mkszfile
#
Cela génère un fichier similaire à celuis présenté ci-dessous :

La syntaxe officielle de la version V6.1 est la suivante :
mkszfile Command
Purpose
Saves the system state for reinstallation on the current system or
another system.
Syntax
mkszfile [ -X] [ -m] [ -N ]
Description
Attention: The mkszfile command overwrites an existing /image.data file
with new information.
The mkszfile command saves the system state for reinstallation on the
current system or on another system. The information saved includes the
following:
* System installation information
* Logical volume information for the root volume group
* File system information.
The saved information allows the bosinstall routine to recreate the
logical volume information as it existed before the backup.
The mkszfile command creates the /image.data file. The contents of this
file are defined by the system in which the image was created. The user
can edit the /image.data file before calling the mksysb command. The
mksysb command, in turn, only backs up the file systems specified in
the /image.data file, which reflects the requirements of the rootvg
file system.
All the saved information is obtained using list commands. The commands
are listed in the /image.data file as comments for the user's reference
when editing this file.
Files on tape cannot be changed. However, in order to override the data
files on the tape, the user can create a diskette with the desired
files.
The mkszfile command checks to be sure there is at least 8MB of free
space available in the /tmp file system for the boot image. Note:
1 Before running the mkszfile command, ensure that enough space is
available in the /tmp file to store a boot image. This space is
needed during both backup and installation. To determine the
amount of space needed in the /tmp file, issue one of the
following commands: bosboot -qad rmt or bosboot -qad ipldevice.
2 If you remove the /dev/ipldevice prior to executing the mkszfile
command, the 0301-150 bosboot error occurs. This message, in most
cases, can be ignored. Confirm the success of the mkszfile command
by the return code.
Flags
Item
Description
-m
Creates map files that specify the mapping of the logical-to-
physical partitions for each logical volume in the volume group.
This mapping can be used to allocate the same logical-to-physical
mapping when the image is restored. The map file locations are
stored in the MAPFILE field in the /image.data file for each
logical volume. Sufficient space would exist in the /tmp file
system for map creation because the installation routines place
the maps in the /tmp file system before issuing the mklv command.
For example, for the hd7 logical volume, the location of the map
file is /tmp/vgdata/rootvg/hd7.map. The MAPFILE field in the
/image.data file for the hd7 logical volume is under the entry
MAPFILE=/tmp/vgdata/rootvg/hd7.map.
The map files in the backup image are copied after the
/bosinst.data and /image.data files.
-N
Includes file systems that belong to a workload partition (WPAR)
in the defined state in the /image.data file. Note: To be included
in the /image.data file, all file systems that belong to a WPAR in
the defined state need to be in the rootvg volume group.
-X
Expands /tmp if needed.
