Installazione Server su rack (caso Server DELL)

  • Pesare server e collocarlo dove il peso lo consente
  • Collegare solo cavi rame blu (managment)

  • Avvisare SERGIO con queste info PRIMA DI ATTACCARE FIBRA E CAVI GRIGI

    Prima di attaccare il resto del cablaggio (fibra e rame non managment) comunicare sempre a Sergio dove devono essere attaccati i cablaggi  (numero porta)
    CAVI GRIGI:  su switch dellcld.lan 
    FIBRA: per macchine INFN switch Mellanox, per Università Cisco o Juniper
    Comunicare nome macchina "cld-np-xx" per configurazione cld-nat
    Quando Sergio da OK e comunica IP, si può procedere a collegare i cavi e ad accendere la macchina

  • Dopo aver collegato fibra e cavi grigi, accendere la macchina (F2 > Idrac Settings > Network > Common settings ) e da console configurare i seguenti parametri:
    DNS Drac Name → cld-np-xx
    Static DNS Domain Name → rmc.pd.infn.it
    Enable IPV4 → "ENABLE"
    Enable DHCP → "DISABLE"
    IP Address → 192.168.210.xxx (RMC comunicato da Sergio)
    Gateway → 192.168.211.254
    Netmask → 255.255.252.0
    DNS → 192.168.208.1 (cld-nat)
    DNS Alternativo → 192.84.143.16 (DNS di Sezione)
    Per impostare il DNS il campo resta disabilitato pertanto "giocando" con le selezioni precedenti si può editare
    IPV6 → "DISABLE"
  • Se tutti i parametri sono ok, ora la macchina è raggiungibile via IDRAC come 
    https://cld-np-xx.rmc.pd.infn.it/
    Nell'etichetta (linguetta che si estrae dal frontale) che si trova sulla macchina, davanti è indicato il numero del Service Tag ed Express Service Code mentre sul retro si trova scritta la password di root iniziale

    Impostare new password di root/Idrac standard 
    In base ai dischi fisici della macchina configurare i virtual disk (chiedere a Sgaravatto se è necessaria un configurazione particolare)
    Create Virtual disk > Raid 1  → accoppiando i dischi uguali
    Virtualization → "ENABLE"
    Logical processor → "ENABLE"
    Bios  > Platform > Virtualization  →  "MAX PERFORMANCE"

    Reboot Macchina



yum install epel-release

yum install puppet


Then create the file puppet.conf in /etc/puppet/ or /etc/puppetlabs/puppet/ (the path depends on the version of puppet) with this content (replace 'cld-rbt-test-03' with your hostname):


# This file can be used to override the default puppet settings.

Run puppet:

Couldn't fetch certificate from CA server; you might still need to sign this agent's certificate (cld-rbt-test-03.cloud.pd.infn.it).
Exiting now because the waitforcert setting is set to 0.


In case of errors (because the host was already in puppet) see


[root@cld-config files]# puppetserver ca clean --certname cld-rb-test-03.cloud.pd.infn.it

On cld-config:


[

The host should now appear on foreman.

Move it to the proper host group (e.g. hosts_all)


Enable and start puppet on the host:


[root@cld-rbt-test-03 ~]# systemctl start puppet
[root@cld-rbt-test-03 ~]# systemctl enable puppet
Created symlink /etc/systemd/system/multi-user.target.wants/puppet.service → /usr/lib/systemd/system/puppet.service.
