contains the original size of the logical volume. This field does not reflect any
changes, so you can always return to this value if you inadvertently change the
size. The Minimum size indicates the recommended minimum size of a filesystem
that is required to contain the filesystem data. The PVs selected field contains the
number of physical volumes currently assigned to the volume group for this
logical volume and to the logical volume itself.
The box at the upper-right portion of the screen contains VG Space information
for the volume group to which the logical volume is assigned. This information is
updated to reflect any changes that are made to the logical volume affecting its
size. Also, if the volume group name is changed, the box is updated to reflect the
values for the new volume group.
The following fields can be changed for the logical volume:
Create this LV?
Indicates whether of not this logical volume (and filesystem) will be
created. If you enter “n” to not create the logical volume, no other fields
can be changed. This logical volume is not created and, if installing a
system, the logical volume or filesystem data is not restored from the
backup media.
If the field currently contains “no,” enter “y” to create the logical volume,
and you can then change any other field.
If you change the value of this field, the VG Space information box at the
top of the screen is updated to reflect the amount of space used in the
volume group containing this logical volume.
Logical Volume name
The name of the selected logical volume. You can change the name of the
current logical volume by entering a new logical volume name in this field.
You can only enter a logical volume that is not currently defined on the
active system or on the backup media.
Volume Group name
The volume group in which the logical volume currently exists. To move
the logical volume into a different volume group, enter the new volume
group name. The volume group name entered must be currently active or
must be another volume group recreated from the backup media.
If the volume group name is changed, the VG Space information box at
the top of the screen is updated to reflect the new volume group.
If the selected logical volume contains a filesystem, then you must use a
Journaled Filesystem Log (jfslog) logical volume in the new volume group to
mount the filesystem. If the logical volume is moved to a new volume
group, the /etc/filesystems file is updated automatically and the filesystem
is mounted using the first available jfslog logical volume in the new
volume group. If there is no jfs log for that file system type in the new
volume group, SysBack will automatically create one for you provided that
there is enough disk space allocated to your volume group.
Size (in LPs)
The size of the logical volume in logical partitions. The actual disk space
required by this logical volume is the number of logical partitions
multiplied by the number of copies (indicated in the next field). To change
the size of the logical volume, enter a new value.
