HP SmartArray RAID Controller – Comandi CLI su VMware ESXi

Monitoraggio e Gestione HP SmartArray su VMware ESXi

Problema

Su un server HP, è necessario monitorare o gestire un controller RAID SmartArray.

Fonte

Consulta la guida completa qui

Soluzione

Se VMware ESXi è stato installato usando una ISO Custom di HPE, sotto la directory /opt sono già presenti strumenti per gestire il controller RAID SmartArray.

Se invece è una versione generica di ESXi, è necessario scaricare e installare un pacchetto ZIP o un file VIB con i tool corretti.

Esempi e Comandi Utili

Ricorda di sostituire lo slot corretto dove è inserito il controller RAID SmartArray.

Mostrare la configurazione

  • ESXi 5.5: /opt/hp/hpssacli/bin/hpssacli ctrl all show config
  • ESXi 6.5: /opt/smartstorageadmin/ssacli/bin/ssacli ctrl all show config

Stato del controller

  • ESXi 5.5: /opt/hp/hpssacli/bin/hpssacli ctrl all show status
  • ESXi 6.5: /opt/smartstorageadmin/ssacli/bin/ssacli ctrl all show status

Dettagli del controller

  • Tutti i controller:
    • ESXi 5.5 → /opt/hp/hpssacli/bin/hpssacli ctrl all show detail
    • ESXi 6.5 → /opt/smartstorageadmin/ssacli/bin/ssacli ctrl all show detail
  • Controller nello slot 0:
    • ESXi 5.5 → /opt/hp/hpssacli/bin/hpssacli ctrl slot=0 show detail
    • ESXi 6.5 → /opt/smartstorageadmin/ssacli/bin/ssacli ctrl slot=0 show detail

Rilevare nuovi dispositivi

  • ESXi 5.5 → /opt/hp/hpssacli/bin/hpssacli rescan
  • ESXi 6.5 → /opt/smartstorageadmin/ssacli/bin/ssacli rescan

Gestione dei Dischi

Stato dischi fisici

  • ESXi 5.5 → /opt/hp/hpssacli/bin/hpssacli ctrl slot=0 pd all show status
  • ESXi 6.5 → /opt/smartstorageadmin/ssacli/bin/ssacli ctrl slot=0 pd all show status

Dettagli dischi fisici

  • ESXi 5.5 → /opt/hp/hpssacli/bin/hpssacli ctrl slot=0 pd all show detail
  • ESXi 6.5 → /opt/smartstorageadmin/ssacli/bin/ssacli ctrl slot=0 pd all show detail

Stato dischi logici

  • ESXi 5.5 → /opt/hp/hpssacli/bin/hpssacli ctrl slot=0 ld all show status
  • ESXi 6.5 → /opt/smartstorageadmin/ssacli/bin/ssacli ctrl slot=0 ld all show status

Visualizzare stato RAID (percentuale ricostruzione)

  • ESXi 5.5 → /opt/hp/hpssacli/bin/hpssacli ctrl slot=2 ld 1 show
  • ESXi 6.5 → /opt/smartstorageadmin/ssacli/bin/ssacli ctrl slot=2 ld 1 show

Creazione e Modifica Volumi RAID

  • RAID 0:
    • ESXi 5.5 → /opt/hp/hpssacli/bin/hpssacli ctrl slot=0 create type=ld drives=1I:1:2 raid=0
    • ESXi 6.5 → /opt/smartstorageadmin/ssacli/bin/ssacli ctrl slot=0 create type=ld drives=1I:1:2 raid=0
  • RAID 1:
    • ESXi 5.5 → /opt/hp/hpssacli/bin/hpssacli ctrl slot=0 create type=ld drives=1I:1:1,1I:1:2 raid=1
    • ESXi 6.5 → /opt/smartstorageadmin/ssacli/bin/ssacli ctrl slot=0 create type=ld drives=1I:1:1,1I:1:2 raid=1
  • RAID 5:
    • ESXi 5.5 → /opt/hp/hpssacli/bin/hpssacli ctrl slot=0 create type=ld drives=1I:1:1,1I:1:2,2I:1:6,2I:1:7,2I:1:8 raid=5
    • ESXi 6.5 → /opt/smartstorageadmin/ssacli/bin/ssacli ctrl slot=0 create type=ld drives=1I:1:1,1I:1:2,2I:1:6,2I:1:7,2I:1:8 raid=5

Altre operazioni

  • Elimina volume logico: ld 2 delete
  • Aggiungi dischi fisici a un volume logico: ld 2 add drives=2I:1:6,2I:1:7
  • Aggiungi dischi spare: array all add spares=2I:1:6,2I:1:7
  • Abilita/Disabilita cache scrittura: modify dwc=enable o modify dwc=disable
  • Cancella disco fisico: pd 2I:1:6 modify erase

Funzioni Avanzate

  • LED disco: accendi con led=on, spegni con led=off
  • Rapporto cache lettura/scrittura: modify cacheratio=100/0
  • Abilita scrittura senza batteria: modify nbwc=enable
  • Abilita o disabilita cache volume logico: arrayaccelerator=enable o disable
  • SSD Smart Path: ssdsmartpath=enable o disable

Nota: Usa sempre cautela quando modifichi configurazioni RAID o cache. Verifica i backup prima di apportare modifiche.
