No option to scan a host in Vcenter 5.5?

[IDAVCP]

We are currently running VCenter 5.5. We wanted to patch/update our ESXI hosts. However once right clicked on one of the hosts the option to scan disappeared. We checked our permissions and we still have admin rights in Vcenter.

How/why would that option disappear? Do we need to install VUM? If we do install it will it automatically update Vcenter to 6,0?

Thanks in advance

HI,

Are you sure if the scan option is not available only for one host or ALL host in vCenter ?. This is very unlikely event on just one host. If that is case just try to re-add the host to vCenter, my best guess is it could be VPXA communication issue with ESXI host and re-adding the host to vCenter should solve it.

I have seen cases where scan option is not available in all the host when the VUM plugin is disabled state. Check in vSphere client Plugin -> manage plugin -> status of VUM plugin. It should be in enabled state.

Thanks,

Chaary

Based on your questions it looks you have not installed VMware update manager.

You need to install VMware update manage on serverr, then enable plugin on client to patch, upgrade esxi host.

Update manager do not help to upgrade vCenter server.

To patch, upgrade vcenter you need to run vCenter installer.

Thanks,
