Imaging Computers
The basic process (for 1 to ~50 computers):
- Prep
computer is set up according to ComputerConfiguration (only needs to be done once)
network infrastructure is set up according to NetworkConfiguration (only needs to be done once)
- Imaging
- clear out stale config files
[root@drbl ~]# rm /tftpboot/nbi_image/pxelinux.cfg/80*
run dcs command
[root@drbl ~]# dcs
on DRBL, starting an interactive series of questions
use ether-wake, or equivalent script, to wake computer
monitor /var/log/messages on DRBL to see if all computers connect
imaging happens (~30 -- ~50 min)
computer shuts down (this is an optional, but highly recommended, setting in dcs)
- clear out stale config files
