vCenter Single Sign-On – no healthy upstream

Tra le migliaia di cause per questo dannato errore di “no healthy upstream” c’è anche la possibilità che i certificati interni siano scaduti.

Ci troviamo con una pagina bianca (o scura, a seconda del tema…) e la sola dicitura “no healthy upstream”:

Tra le possibili soluzioni, prima di tentare una reinstallazione completa del vCenter, verifichiamo che i certificati siano ok. Da una sessione SSH proviamo a fare un controllo

root@vcenter [ /etc/vmware/vsphere-ui ]# for store in $(/usr/lib/vmware-vmafd/bin/vecs-cli store list | grep -v TRUSTED_ROOT_CRLS); do echo "[*] Store :" $store; /usr/lib/vmware-vmafd/bin/vecs-cli entry list --store $store --text | grep -ie "Alias" -ie "Not After";done;

Otteniamo un elenco dei certificati e delle scadenze

Ci sono un paio di certificati scaduti, dannato mondo. Andiamo nella cartella /usr/lib/vmware-vmca/bin e eseguiamo il certificate-manager

Option[1 to 8]: 8

Resettiamo tutto con l’opzione “8”, se serve possiamo:

# service-control --stop vsphere-ui
# service-control --start vsphere-ui

Dovrebbe essere tutto ok 🙂
