3 Repeat the upgrade operation.
See Upgrade a VMFS3 Datastore to VMFS5.
Upgrade a VMFS3 Datastore to VMFS5
After you mount the VMFS3 datastore that failed to upgrade automatically, upgrade it to VMFS5.
Procedure
1 Navigate to the VMFS3 datastore.
2 Select Upgrade to VMFS5 from the right-click menu.
3 Verify that the hosts accessing the datastore support VMFS5.
4 Click OK to start the upgrade.
5 Perform a rescan on all hosts that are associated with the datastore.
The datastore is upgraded to VMFS5 and is available to all hosts that are associated with the datastore.
Understanding Network File System Datastores
An NFS client built into ESXi uses the Network File System (NFS) protocol over TCP/IP to access a
designated NFS volume that is located on a NAS server. The ESXi host can mount the volume and use it
for its storage needs. vSphere supports versions 3 and 4.1 of the NFS protocol.
Typically, the NFS volume or directory is created by a storage administrator and is exported from the NFS
server. You do not need to format the NFS volume with a local file system, such as VMFS. Instead, you
mount the volume directly on the ESXi hosts and use it to store and boot virtual machines in the same
way that you use the VMFS datastores.
In addition to storing virtual disks on NFS datastores, you can use NFS as a central repository for ISO
images, virtual machine templates, and so on. If you use the datastore for the ISO images, you can
connect the CD-ROM device of the virtual machine to an ISO file on the datastore. You then can install a
guest operating system from the ISO file.
NFS Protocols and ESXi
ESXi supports NFS protocols version 3 and 4.1. To support both versions, ESXi uses two different NFS
clients.
Comparing Versions of NFS Clients
The following table lists capabilities that the NFS version 3 and 4.1 support.
Characteristics NFS version 3 NFS version 4.1
Security mechanisms AUTH_SYS AUTH_SYS and Kerberos (krb5 and krb5i)
Encryption algorithms with Kerberos N/A AES256-CTS-HMAC-SHA1-96 and
