Write-cache redirected to server in Citrix Provisioning

Possible Cause 1 : San Policy “Citrix Provisioning clients always failover to server side cache during boot when the virtual disk mode is set to Cache in device RAM with overflow on hard disk.” according to Citrix documentation above

 

The solution is to apply the Diskpart command: “san policy=online all”

Per Citrix documentaion:

In a provisioning target device booting in private virtual disk mode or maintenance virtual disk version, open a command prompt with administrator privileges.

Run the DiskPart utility, using the following command:

Diskpart – Press [Enter], followed by:

san – Press [Enter], (To verify the current SAN policy)

san policy=OnlineAll – Press [Enter], (To modify the current SAN policy to  allow it to function correctly while in Cache in Device RAM with Overflow on Hard Disk mode.)

 

Possible cause 2: The Write cache drive is not formatted

Solution: You need to boot the vDisk in private or maintenance mode, open Disk Management and format the write cache drive to make it active

Symptom:

When you configured the vDisk to use Cache in Device RAM with Overflow on Hard Disk mode but when booting the target device this is what you see:

Good luck!
