Imaging Computers
Capturing an Image
- 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)
run through the ImageChecklist to see that software meets requirements
- Imaging
- clear out stale config files
[root@drbl ~]# rm /tftpboot/nbi_img/pxelinux.cfg/80*
run dcs command
[root@drbl ~]# /opt/drbl/sbin/dcs
on DRBL, starting an interactive series of questions
Follow the prompts to specify computer by IP, clonezilla start, save disk, beginner or expert, shutdown (at your option)
- Boot prepped computer from network
- Should be hands-off, imaging happens (30-50 minutes)
- Computer turns off
- clear out stale config files
Deploying an Image
- Prep
- Shouldn't be much, boot all computers to the boot media selection screen in BIOS (press F12 shortly after power-on)
- Imaging
- clear out stale config files
[root@drbl ~]# rm /tftpboot/nbi_image/pxelinux.cfg/80*
run dcs command
[root@drbl ~]# /opt/drbl/sbin/dcs
on DRBL, starting an interactive series of questions:
Follow prompts to select a group of PCs by IP address
choose clonezilla start, restore disk, beginner or expert, multicast restore (for multiple PCs), choose image (created after the Capturing an Image step in /home/partimage/<image_name>), shutdown (at your option)
- Boot prepped computer from network
- Should be hands-off, imaging happens (10-40 min, slightly shorter than capturing)
- Computer turns off
- clear out stale config files
