Host Caching Settings Issue

[gogogo5]

Hello

I have a VMware View 5.1 environment connecting to a vSphere 5.0 U1 environment.  When enabling Host Caching on the View Configuration > Servers > Select VC > Host Caching tab and clicking OK, the ESXi hosts are not configured.  This is verified by checking an individual ESXi host Advanced Configuration > CBRC settings.

Looking at the View Connection Manager logs I see this:

The vCenter user account used for View is an Administrator in VC and set at the VC level as per the documentation.  Can anyone suggest why the permission problems would be occurring?  Do any of you get these messages in your View logs when disabling/enabling the Host Caching feature???

Cheers

Whenyou enable Host caching for a VC through View administrator, ESXi hosts are not configured immediately.

Go ahead, and create a pool, and enabe the pool settings "Use Host Caching" in the advanced storage options.

During the pool creation (if automated pool) , you can see a VC task called "Update option values" ESXi is configured for host caching at this time.

An ESXi is enabled for host caching only when, atleast one of the VM in the host is configred to use host caching

I had similar errors and had to give my VC user the privilege to change advanced config options for hosts.  This is so it can enable the CBRC in advanced settings.

<privilegeId>Host.Config.AdvancedConfig</privilegeId>

Hi bretttenney - spot on!  My VC user is a custom role created as per the VMware documented privileges including the "Act as vCenter Server" privilege (page 19 & 132 View 5.1 Admin PDF).  This is the privilege that is supposed to grant it rights to change the CBRC settings.

I added the additional privilege to the role from your reply (Host > Configuration > Advanced Settings) and the permission errors do not occur now.

Thanks
