VSAN-Troubleshooting-Reference-Manual

Diagnostics and Troubleshooting Reference Manual – Virtual SAN
The interesting parts are highlighted in bold. There are two objects visible, the VM
Home Namespace and the VMDK (referred to as Disk backing in the above output).
Again, the VM Home is using a StripeWidth=1, where the VMDK is using a
StripeWidth=2. Therefore the VMDK has RAID_0 configurations in each replica,
whereas the VM Home does not.
Another important point is that all components are ACTIVE. There are no
components in an STALE, ABSENT or DEGRADED state.
vsan.object_info
If you note the outputs from vsan.vm_object_info, a “DOM object” reference is
displayed. DOM is short for Distributed Object Manager and is a core component of
Virtual SAN that implements the RAID configuration. Using this “DOM object”
information, one can ask Virtual SAN to display similar information about the object
via a different RVC command called vsan.object_info. Note that this command
must be run against a cluster and not against a virtual machine as was the case with
the previous command.
