System Recovery: Creating a Bootable Recovery Tape
NOTE The system recovery tape is only as good as the last time it was created.
The tape should be re-created if new software, hardware, or patches have
been added. You can use the check_recovery to determine whether the
system has changed enough that the tape needs to be re-created.
Logging Progress and errors are logged to the file /var/opt/ignite/logs/mkrec.log*.
Recovery Example for
Minimal OS
The following operations are done as root.
To create a minimal operating system recovery tape at /dev/rmt/0mn,
containing only the OS elements required to boot the system, do the
following:
1. Load a writeable tape in the default DDS drive for your system.
2. Enter the following:
# make_recovery
A tape will be created without further interaction.
System recovery from this tape would involve booting from the tape to
recover the minimum Core OS. Then you would follow up with data
recovery of user files from the usual backup media.
Default Recovery of
Entire Root Disk
To create a System Recovery tape, at the default device /dev/rmt/0m,
and includes the entire root disk in the archive, you would do the
following:
1. Load a writeable tape in the default DDS device for your system.
2. Enter the following:
# make_recovery -A
A tape will be created without further interaction.
Duplicating a System To duplicate a system, you can create a system recovery tape by doing
the following:
1. Load a writeable tape in the default DDS device for your system.
2. Enter the following:
# make_recovery
A tape will be created without further interaction.
You can boot this tape on your new system.
