Note: The maximum physical extents of a boot disk is 5628. If desired, increase
the PE size for larger hard disks.
A golden system image can be written onto tape if desired:
# /opt/ignite/data/scripts/make_sys_image -d /dev/rmt/0m -s local
When using make_sys_image, important system files are temporarily replaced which
leads to intensive disruptions on a productive system, among other things, the name
resolution, login, etc. Therefore, if make_sys_image is run the system should never
be in use by other applications!!!
If a make_sys_image was disrupted e.g. with # kill -9, # shutdown, etc., then
among other things the /etc/hosts and the transition links may have also been
removed. To recover from missing transition links, do the following in the multi-user
run level:
# /sbin/pax -r -pe –f /tmp/ign_configure/keepsafe
# /opt/upgrade/bin/tlinstall
Ignite-UX System Recovery Tools - Limitations
Logical Volume Physical Extent Allocation Not Preserved:
The LVM physical extents allocated to a logical volume may be in a different location on the
disk than before. The recovery tools use a very specific and complex algorithm for extending
logical volumes to ensure success (such as extending contiguous volumes before non-
contiguous).
LVM Disk Mirrors not restored:
The tools will create a recovery tape for a system with mirrored disks, but it will not restore the
mirrored disk configuration. If the system is later recovered, previously mirrored volumes will
no longer be mirrored. They can be manually re-mirrored after the system is up. For more
details, see the white paper /opt/ignite/share/doc/diskmirror.pdf.
EFI partition on Itanium systems may grow in size:
Beginning with Ignite-UX version C.6.0.x the default EFI partition size changed from 100MB to
500MB, in order to accommodate enough space for new purposes not yet implemented. If the
EFI partition was 100MB it will be resized to 500MB during recovery. This may introduce disk
space problems, if the disk is fully used. You can change the default size from 500MB to any
other size in the installation routine.
