It is recommended that a backup of the current AS/U environment
be made before proceeding with a new installation. The SD install
and asu_inst installation programs may alter
or replace your current configuration files. Therefore, in order
to be able to restore your current configuration, all files under
/var/opt/asu/lanman and /etc/opt/asu/lanman
must be backed up. In the following example, "$"
represents the command prompt, and commands that are too long to
fit on this printed page are indicated with "\"
as the line-continuation character:
$ net stop server
$ mkdir /tmp/asu_save
$ tar -cvf /tmp/asu_save/asu_backup_var.tar \
/var/opt/asu/lanman
$ tar -cvf /tmp/asu_save/asu_backup_etc.tar \
/etc/opt/asu/lanman
To ensure that correct file-ownership data is preserved, do
not use the -o option to tar.
If a problem occurs with the upgrade, you can then run asu_rmv
to remove the entire AS/U product, use SD to reinstall your current
AS/U version, restore the saved configuration files--for example:
tar -xvf /tmp/asu_save/asu_backup_var.tar tar -xvf /tmp/asu_save/asu_backup_etc.tar
and then run asu_inst to complete the restoration.Note:
This simple procedure is not a replacement for a comprehensive backup
strategy that also includes user data files.
