Change Default Crowbar (v1.1) Admin IP

These notes summarise what is shown in this video. Internally it is chef that manages the IP address of crowbar.

Important: do not run crowbar's installer until network changes are made.

0. Install from crowbar iso

1. Once installed and booted, login as crowbar:crowbar

2. sudo -i

3. cd /opt/dell/barclamps/network/chef/data_bags/crowbar

4. vi bc-template-network.json

5. Edit the parameters under "admin" : {…} (You can ignore VLAN settings currently).

6. Change the various settings (IP address, Subnet, etc). Note that there should be a value for router, however the installer doesn't currently use it. There are different DHCP ranges:

   • admin: this is the IP range for crowbar administrative nodes.
   • dhcp: this is the IP range for nodes receiving/changing roles via discovery and control process
   • host: this is the IP range for crowbar managed nodes (e.g. nova, swift nodes)
   • switch: this is the IP range reservation for switch IP allocations. This is currently not used in Crowbar but present for future work.
