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
- login using ssh (Putty on Windows)
run dcs command
[yourusername@drbl ~]# sudo dcs
on DRBL, starting an interactive series of questions
Follow the prompts to specify computer by IP, clonezilla start, save disk, beginner, shutdown (at your option)
- Boot prepped computer from network
- Should be hands-off, imaging happens (30-50 minutes)
- Computer turns off
Deploying an Image
- Imaging
- login to drbl.physics.wisc.edu using sshPutty
run dcs command
[yourusername@drbl ~]# sudo dcs
on DRBL, starting an interactive series of questions:
Follow prompts to select a group of PCs by IP address
choose clonezilla start, beginner, restore disk, reboot (or your option), choose image (created after the Capturing an Image step), multicast restore (for multiple PCs), and set a time which will allow you to get all computers ready.
- At the recieving computer
- Shouldn't be much, boot all computers to the boot media selection screen in BIOS (press F12 shortly after power-on)
- Choose network boot.
- Should be hands-off, imaging happens (10-40 min, slightly shorter than capturing)
- Computer turns off
- After multicast is done, turn off clonezilla mode. THIS IS NECESSARY because otherwise the computers might get a wake-on-LAN packet, and then boot from network device. (Boot from network device after waking from LAN is a BIOS option which is turned on at the moment.)
- Again start DRBL
[yourusername@drbl ~]# sudo dcs
Select a All clients, clonezilla stop. (Will take awhile to return to command line.)
