6.2 Software installation and configuration
6.2.1 Boot modes
A
can be installed to be operated in normal boot mode or in eXtended safety boot mode.
RGUS
Normal boot mode
With normal boot mode the hard disk of the A
system is configured to have one partition, this is the working
RGUS
partition. Underlying is the ext3 file system that offers widely immunity to file corruption in case of power failure
or when switching of the system without having performed a system shutdown before.
An A
with normal boot mode offers full write access to the system partition. To configure A
just insert the
RGUS
RGUS
configuration disk into the CD-ROM or call the corresponding configuration script from the hard disk and perform
D-ROM or call the corresponding configuration script from the hard disk and perform
the configuration as explained in the corresponding sections.
Although the ext3 file system offers good protection against file system inconsistencies, for safely switching off,
the system has to be shut down first (see section
3.3.3 Switching
off).
eXtended safety boot mode
With eXtended safety boot mode the hard disk of the A
system contains two partitions, the working partition
RGUS
and the backup partition. eXtended safety boot mode is like normal boot mode also based on the ext3 file sys-
tem. But in addition it offers the possibility to store on the backup partition a backup of the whole system in-
cluding its configuration. A backup with the current state of the working partition can be made at any time and
the working partition can easily be restored in case of a miss-configuration or failure in operability. Please see
Please see
section
4.8.5 Backup and restore procedures (eosxs Utility)
for details.
eXtended safety boot mode is the recommended boot mode for A
.
