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

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.)
