running a chkdsk on a VM which is on a local hosts disk.

wondered whether this actually how this works? e.g. clever enough to run it on the vmx etc, the whole raid, pointless?

thanks

Chkdsk will run inside a VM, chdsk is not aware that the machine is a virtual or the disk is virtual.

So it will repair it as normal if required.

However, this will not check or test the VMFS datastore for corruption, it will not check the vmdk for corruption, you will need to be on the host for that.

chkdsk is a Windows function.

use the  VOMA command, see here for syntax

..(remember VMFS is a partition on a RAID disk, VMFS is not RAID-ed!)

Using vSphere On-disk Metadata Analyzer (VOMA) to check VMFS metadata consistency

The Physical Disks and condition of the RAID arrays should be monitored with the Server manufacturer's tools. If you installed the ESXi version of the Server's Manufacturer, you should be able to do this via the VMWare management tool. If you didn't install that version, you should be able to boot the server into the controller's utility via a hotkey, and check things out there, or via the management CD/DVD you got with the server.
