La documentazione per questo prodotto è stata redatta cercando di utilizzare un linguaggio senza pregiudizi. Ai fini di questa documentazione, per linguaggio senza di pregiudizi si intende un linguaggio che non implica discriminazioni basate su età, disabilità, genere, identità razziale, identità etnica, orientamento sessuale, status socioeconomico e intersezionalità. Le eventuali eccezioni possono dipendere dal linguaggio codificato nelle interfacce utente del software del prodotto, dal linguaggio utilizzato nella documentazione RFP o dal linguaggio utilizzato in prodotti di terze parti a cui si fa riferimento.

Cisco ha tradotto questo documento utilizzando una combinazione di tecnologie automatiche e umane per offrire ai nostri utenti in tutto il mondo contenuti di supporto nella propria lingua. Si noti che anche la migliore traduzione automatica non sarà mai accurata come quella fornita da un traduttore professionista. Cisco Systems, Inc. non si assume alcuna responsabilità per l’accuratezza di queste traduzioni e consiglia di consultare sempre il documento originale in inglese (disponibile al link fornito).
Questo documento descrive i passaggi necessari per sostituire un server di elaborazione difettoso in una configurazione Ultra-M che ospita funzioni di rete virtuale (VNF) StarOS.
Ultra-M è una soluzione di base di pacchetti mobili preconfezionata e convalidata, progettata per semplificare l'installazione di VNF. OpenStack è Virtualized Infrastructure Manager (VIM) per Ultra-M ed è costituito dai seguenti tipi di nodi:
L'architettura di alto livello di Ultra-M e i componenti coinvolti sono illustrati in questa immagine:
Questo documento è destinato al personale Cisco che ha familiarità con la piattaforma Cisco Ultra-M e descrive i passaggi richiesti per essere eseguiti a livello OpenStack e StarOS VNF al momento della sostituzione del server di elaborazione.
Nota: Per definire le procedure descritte in questo documento, viene presa in considerazione la release di Ultra M 5.1.x.
VNF | Funzione di rete virtuale |
CF | Funzione di controllo |
SF | Funzione di servizio |
ESC | Elastic Service Controller |
MOP | Metodo |
OSD | Dischi Object Storage |
HDD | Unità hard disk |
SSD | Unità a stato solido |
VIM | Virtual Infrastructure Manager |
VM | Macchina virtuale |
EM | Gestione elementi |
UAS | Ultra Automation Services |
UUID | Identificatore univoco universale |
Prima di sostituire un nodo di calcolo, è importante verificare lo stato corrente dell'ambiente della piattaforma Red Hat OpenStack. Si consiglia di controllare lo stato corrente per evitare complicazioni quando il processo di calcolo sostitutivo è attivo. Questo flusso di sostituzione consente di ottenere il risultato desiderato.
In caso di ripristino, Cisco consiglia di eseguire un backup del database OSPD attenendosi alla seguente procedura:
[root@director ~]# mysqldump --opt --all-databases > /root/undercloud-all-databases.sql
[root@director ~]# tar --xattrs -czf undercloud-backup-`date +%F`.tar.gz /root/undercloud-all-databases.sql
/etc/my.cnf.d/server.cnf /var/lib/glance/images /srv/node /home/stack
tar: Removing leading `/' from member names
Questo processo assicura che un nodo possa essere sostituito senza influire sulla disponibilità di alcuna istanza. È inoltre consigliabile eseguire il backup della configurazione StarOS, soprattutto se il nodo di calcolo da sostituire ospita la macchina virtuale (VM) della funzione di controllo (CF).
Identificare le VM ospitate nel server di elaborazione. Esistono due possibilità:
[stack@director ~]$ nova list --field name,host | grep compute-10

Nota: Nell'output mostrato di seguito, la prima colonna corrisponde all'UUID (Universally Unique IDentifier), la seconda colonna è il nome della macchina virtuale e la terza colonna è il nome host in cui la macchina virtuale è presente. I parametri di questo output verranno utilizzati nelle sezioni successive.

I passaggi menzionati in questa sezione sono comuni indipendentemente dalla VM ospitata dal nodo di calcolo.
Creare un file add_node.json contenente solo i dettagli del nuovo server di elaborazione da aggiungere. Verificare che il numero di indice per il nuovo server di elaborazione non sia stato utilizzato in precedenza. In genere, incrementa il valore di calcolo successivo più alto.
Esempio: La versione precedente più alta era compute-17, quindi creò compute-18 nel caso del sistema 2-vnf.
Nota: Prestare attenzione al formato json.

Salvare la riga boot_vm.py in un file di script della shell (esc.sh) e aggiornare tutte le righe relative al nome utente ***** e alla password ***** con le informazioni corrette (in genere core/<PASSWORD>). È necessario rimuovere anche l'opzione -encrypt_key. Per user_pass e user_confd_pass, è necessario utilizzare il formato - nome utente: password (esempio - admin:<PASSWORD>).

Nei casi in cui ESC non riesca ad avviare la macchina virtuale a causa di uno stato imprevisto, Cisco consiglia di eseguire il switchover di ESC riavviando la macchina virtuale master. Il passaggio al CES richiede circa un minuto. Eseguire lo script "health.sh" sul nuovo Master ESC per verificare se lo stato è attivo. Master ESC per avviare la macchina virtuale e correggere lo stato della macchina virtuale. L'attività di ripristino può richiedere fino a 5 minuti.
È possibile monitorare /var/log/esc/yangesc.log e /var/log/esc/escmanager.log. Se NON si vede che la VM viene ripristinata dopo 5-7 minuti, l'utente deve procedere al ripristino manuale delle VM interessate.
Da AutoDeploy VM, modificare il file autodeploy.cfg e sostituire il vecchio server di elaborazione con quello nuovo. Caricare quindi replace in confd_cli. Questo passaggio è necessario per la corretta disattivazione della distribuzione in seguito.
