### Baremetal Hardware

We have some interconnected hardwares which we used for traditional tripleo deployments.

:::warning
Really old infra - warranty expired 6 years ago)
:::

### Current status of baremetal servers
* EnvA(Dell) - 17.1/9
* EnvB(Dell) - 17.0/9 (Removed this week after a hardware failure on 1 node)
* EnvC Decommissioned - got New Baremetal - Not used anywhere, not inter connected.
* EnvD(HP) - 16.2/8
* EnvE(HP) - Not used anywhere. (But environment is good, no hardware issues till last time when we ran this environment)

# Network Topology of our infra


# Where to find actual vlan/network info?

- https://code.engineering.redhat.com/gerrit/plugins/gitiles/tripleo-environments/+/refs/heads/master/hardware_environments/
- Separate directory for each baremetal env

# Job definition

We use zuul `Semaphore`: Semaphores can be used to restrict the number of certain jobs which are running at the same time.

# How to access environment?

Environment is available even after job finishes

# Reprovision kvm step(only needed when something went wrong or you want to move to different rhel version)

If you ever had to reprovision kvm box - you can use reprovision it using PXE from lab PXE server or via virtually mounting DVD ISO

you will need following on blank kvm box after reprovisioning
~~~
1. Copy jenkins key
$ ssh-copy-id -i ~/.ssh/id_rsa_rdoci-jenkins [e-mail]

2. Install repos
dnf install -y http://download.lab.bos.redhat.com/rcm-guest/puddles/OpenStack/rhos-release/rhos-release-latest.noarch.rpm
rhos-release -u -r 9.2

3. Install cert
dnf install -y http://hdn.corp.redhat.com/rhel8-csb/RPMS/noarch/redhat-internal-cert-install-0.1-31.el7.noarch.rpm

4. Install libvirt and update
dnf update -y
dnf install libvirt -y

reboot if kernel update

5. Add following ports in firewall and reload firewall

firewall-cmd --add-service tftp --zone=public --permanent
firewall-cmd --add-service dhcp --zone=public --permanent
firewall-cmd --add-service dns --zone=public --permanent
firewall-cmd --add-service dhcpv6 --zone=public --permanent
firewall-cmd --zone=libvirt --add-port=69/tcp --permanent
firewall-cmd --zone=libvirt --add-port=69/udp --permanent
firewall-cmd --zone=libvirt --add-port=67/udp --permanent
firewall-cmd --zone=libvirt --add-port=67/tcp --permanent
firewall-cmd --zone=libvirt --add-port=68/tcp --permanent
firewall-cmd --zone=libvirt --add-port=68/udp --permanent

firewall-cmd --reload

6. Troubleshooting - if after reprovision you hit introspection/provisiong issue

Check if eno2 is connected to brovc bridge, once/twice i hit that issue and fixed that by connecting eno2 under brovc bridge using RHEL console GUI.
