Configuration:

Netapp (SAN) providing a 5GB FC LUN to VMware hosts (datastore).

(2) Server 2012R2 datacenter VMs configured with a 5GB shared vmdk using paravirtual SCSI controller with SCSI Bus sharing set to "Physical" for hosting data.

Problem:

Whenever I put a file on the shared disk on VM1, the data does not show up on VM2. I have to reboot VM2 in order for the data to show up.

I am requiring this configuration for a failover cluster for my subordinate Certificate Authority servers thus the requirement to have data show up immediately.

In SCCM - when I add a computer to the Devices and then to a custom device collection, it takes a long time for it to show up in the Custom Device Collection. Is there a way to manipulate this time? I'm assuming that SCCM is goes through a refresh period and when it notices a change, it adds the systems accordingly, or maybe I'm completely wrong on how that works and it's actually doing something else.

Simply put, I'd like for the computer to be added to the Custom Device Collection immediately, how can I accomplish this?

Not to get to deep into the weeds, here's the gist.

A SysAdmin of ours created GPOs on the Domain Controllers Policy (DCP) and we've been having time issues ever since.

Neither he nor I know if the Windows Time Service was configure via GPO previously or not.

I configured the PDC Emulator via command line and got everything working fine.

However, the GPOs for Windows Time Service is still active. I'm asking just for clarification, but I'm pretty sure I know the answer.

Should I re-configure the DCP: Windows Time Service GPOs to "NOT CONFIGURED"?

Also, on the backup Domain Controller (non-PDC), if I configure it for "syncfromflags:domhier" how do I get this system to act as a backup time server for my Linux (SUSE 11) machines which are pointing to the PDC and working properly, but they are not able to get time from the backup DC aka non-PDC emulator? (this is my real question for this thread).
