Backup station is a universal station which can be used as a temporary replacement of any station in assembly line. So that this station should be hardware universal too.
To configure PLC backup station follow these steps:
1) Install the station PC as a common station
2) Modify a boot menu
Modify of /boot/grub/grub.conf file is needed. Each choice (workstation) must include a parameter specific for the station, it includes last number from IP address.
Here is an example of one choice:
title SOME LABEL
root (hd0,0)
kernel /vmlinuz-2.6.36-5.fc15.i686 ro root=/dev/mapper/vg_plcplmbk1-lv_root panic=203
initrd /initramfs-2.6.36-5.fc15.i686.img
savedefault
It is possible to use a script plc_backup_bootmenu_gen to generate the boot menu. Before you use this script, copy the original grub.conf from a desired backup station to a kernel directory $PLC_EtcDir/workstations/backup_pc/grub.conf.master. You can find the generated configuration file in $PLC_EtcDir/workstations/backup_pc/grub.conf. Copy the generated file back to the desired backup station.
3) Change a starting script
Copy this Media:PlcRestore.cfg.zip script to /etc/rc.d directory. Replace an init script in /etc/init/plc.conf (Fedora Core 14) by this one.
