I wanted to put the information needed for NCM for VMware install / update in one place:

 

 

Do I need a dedicated NCM version for each ESXi release

NCM release is is dedicated to each ESXi release, you will find a package for each release (5/6/6.5).

NCM is compatible with previous Nimble OS, when upgrading a Nimble OS, you should also upgrade your NCM software on the host.

 

When do you need to reboot ESXi host

 

* Fresh install of NCM on ESXi 6.0.

* Fresh install of NCM on ESXi 6.5.

* Update or uninstall NCM

 

When do you NOT need to reboot ESXi host

 

* Fresh install of NCM on ESXi 5.x does not require a reboot.

 

Using update manager

When using the VUM only signed VIBs can be used.

 

 

Note: as of 8th of March, NCM 3.4.0 is signed by VMware and it's possible to install it with VUM.

 

 

NCM version 3.4.0 is not signed by VMware for ESXi 5.0/6.0/6.5. Until the NCM bundles are signed by VMware, installation can be done through esxcli command only, and not through the VMware Update Manager.

 

Note:

When installing the VIB, the  --no-sig-check option must be used.

Online bundle installation example for ESXi 6.0:

esxcli software vib install -d https://update.nimblestorage.com/esx6/3.4.0 --no-sig-check

Online bundle installation example for ESXi 6.5:

esxcli software vib install -d https://update.nimblestorage.com/esx6.5/3.4.0 --no-sig-check

Online bundle installation example for ESXi 5.0:

esxcli software vib install -d https://update.nimblestorage.com/esx5/3.4.0 --no-sig-check

 

TLS considerations

Recently Nimble changed the transport layer security (TLS) of the update server (update.nimblestorage.com) to accept TLS v1.2 (see Infosight EXT-0032).

This change impact the ESXi NCM online install, as some ESXi releases do not support TLS v1.2, the full list of compatibility of the ESXi server can be reviewed here:

 

https://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2145796

 

Be sure to check the compatibility of the ESXi server with TLS version.

 

The current settings are as followed:

 

For VMware ESXi 5.1, 5.0 and earlier end of life products, use the offline bundle.

For VMware ESXi 5.5+ NOT on a build supporting TLS v1.2, use the offline bundle.

For VMware 6.x and ESXi 5.5 on a build supporting TLS v1.2, use the online or offline bundle.

 

Also, note that the URL path changed from "http" to "https".
