Recovery Tape
NOTE The copyutil tool is only supported as a diagnostic tool for HP-UX 10.x
or later, and should not be used for recovery. Instead, you should use one
of the tools described in this chapter.
Note also that make_recovery (and booting from tape) is not yet
supported on current HP V- class systems.
The make_recovery command creates a system recovery tape. This
tape can be used to boot and recover a system which has become
unbootable due to corruption of the root disk or volume group. As a
"customized" installation medium, it makes use of the installation
technology provided by Ignite-UX.
A system can be booted and installed from the tape without user
intervention for configuration, customization, software selection,
hostname, or IP address.
The system recovery tape consists of a boot image, followed by an archive
of system files that comprise a minimum core OS. The minimum core OS
consists of /stand, /sbin, /dev, /etc, and subsets of /usr, /opt and
/var that are required during the install process. The devices or volume
groups that correspond to the file systems/directories /, /dev, /etc,
/sbin, /stand, and /usr are considered core devices or volume groups.
These devices or volume groups are recreated during the recovery
process. All non-OS data on them would be removed and restored during
the recovery process, if they were specifically appended to the recovery
tape. If /usr, /opt or /var are mounted elsewhere, they would not be
re-installed during the recovery process, and are fully preserved.
The make_recovery command provides a mechanism for you to specify
your own non-system files in the archive by using the
/var/adm/makrec.append file. These specifications are limited to files
or directories that belong to file systems in the core devices or volume
groups.
The make_recovery command also provides a mechanism for you to
exclude selected files from the archive via the -p and -r options. For
backing-up and recovering non-core file systems which are not on the
core device or volume groups, you would use normal backup utilities.
