Rilevazione dischi
Eseguire il comando per generare un elenco di tutti i percorsi LUN attualmente connessi all'host ESXi. / Run the command to generate a list of all LUN paths currently connected to the ESXi host.
esxcli storage core path list
Run the command to generate a list of LUNs currently connected to the ESXi host.
esxcli storage core device list
Run the command to generate a list of extents for each volume and mapping from device name to UUID.
esxcli storage vmfs extent list
Run the command to generate a compact list of the LUNs currently connected to the ESXi host, including VMFS version.
esxcli storage filesystem list
Se un disco è rilevato ma non viene montato
Questo è visibile dal client o dai comandi:

Possibili scenari:
- La partizione VMFS è corrotta o non viene riconosciuta.
- La tabella delle partizioni è assente o danneggiata.
- Il disco ha un tipo di partizione non VMFS, o nessuna.
- Il volume è stato formattato con una versione VMFS non compatibile (poco probabile tra ESXi 5.x e 6.x).
Per vedere le partizioni presenti:
partedUtil getptbl /vmfs/devices/disks/t10.ATA___...

Rescan
To rescan for new or dead volumes, devices or pathes use
esxcli storage core adapter rescan --all
To scan on a specifc adapter determine the HBA name and start a rescan there
esxcli storage core adapter list vmhba2 lpfc link-up fc.60000090be45e120:10000090be45e120 vmhba3 lpfc link-up fc.60000090be45e121:10000090be45e121
esxcli storage core adapter rescan --adapter vmhba2
To scan for new or changed filesystems use
esxcli storage filesystem rescan
In ESXi 7.x
Smontare (UMOUNT) un datastore
esxcli storage filesystem unmount [-u UUID | -l label | -p path ]
To list the permanently detached devices, run this command:
esxcli storage core device detached list
To permanently remove the device configuration information from the system, run this command:
esxcli storage core device set --state=off -d NAA_ID esxcli storage core device set --state=off -d t10.___...

Montare i volumi
(ESXi 6.5 e 7.x)
lista dei volumi visti ma non montati
esxcfg-volume -l
Risultato
[root@hypervisor2:~] esxcfg-volume -l Scanning for VMFS-3/VMFS-5 host activity (512 bytes/HB, 2048 HBs).

Per montare il volume
esxcfg-volume -m <VMFS UUID|label>
es:
[root@hypervisor2:~] esxcfg-volume -m 63d23a0c-785b4326-c141-00259021346e Mounting volume 63d23a0c-785b4326-c141-00259021346e
per montarlo persistentemente
esxcfg-volume -M <VMFS UUID|label>
per montarlo riassegnando la label
esxcfg-volume -r <VMFS UUID|label>
da provare
