support each file system type included in the volume group provided that
enough disk space is assigned that volume group.
Note: If you set this option globally across the volume group, you may
override this setting for any individual file system to utilize a
different jfs type using theChange Filesystem Attributes menu.
When all selections are complete, press Esc to return to the prior menu.
Note: This option only applies to backups created on systems running AIX 5.1 or
later.
Selecting Physical Volumes for Logical Volumes
SysBack, by default, keeps all logical volumes on the same physical volumes as
they previously resided, provided that the same physical volumes exist on the
current system as those that existed on the original system. If not, the AIX Logical
Volume Manager (LVM) automatically determines a default location for each
logical volume in the volume group based on its size and other attributes selected.
You can, however, select specific physical volumes where you want to place each
logical volume. This is valuable because better I/O performance can be achieved
by placing highly-used logical volumes and filesystems on different physical
volumes.
When a logical volume is striped across multiple physical volumes, achieving the
best I/O performance, you must select the specific physical volumes to use. The
number of physical volumes must be a factor of the number of logical partitions
(size) of the logical volume.
To select physical volumes where you want to place a logical volume, select Select
Physical Volumes for Logical Volumes. A screen similar to the following is
displayed, showing a list of all logical volumes defined on the backup media:
