Virtual machines must deactivate virtual disk wiping operations

MittelStufe 1Automatisiertvmware

Beschreibung

Wiping a virtual disk reclaims all unused space in it. If there is empty space in the disk, this process reduces the amount of space the virtual disk occupies on the host drive. If virtual disk wiping is done repeatedly, it can cause the virtual disk to become unavailable while wiping occurs. Expected: isolation.tools.diskWiper.disable = "TRUE". The audit parses every .vmx file under /vmfs/volumes/ on the host and lists the VMs that do not comply; it passes when none are found (or no VMs exist). Runs in the ESXi Shell (busybox sh) as root.

Behebungsmethode: Anleitung oder Infrastruktur-Patch

To set this configuration utilize the vSphere interface as follows: 1. Select the VM then select Actions followed by Edit Settings. 2. Click on the VM Options tab then expand Advanced. 3. Click on EDIT CONFIGURATION. 4. Click on ADD CONFIGURATION PARAMS then input isolation.tools.diskWiper.disable with a value of TRUE. 5. Click OK, then OK again. To disable virtual disk wiping, run the following PowerCLI command: # Add the setting to all VMs Get-VM | New-AdvancedSetting -Name "isolation.tools.diskWiper.disable" -value $true
