Issue

  • SnapCenter fails to enumerate disks due to error: 

Unable to get storage details for VMDK. 
UUID is not set for VMDK, check if disk.EnableUUID is set for the virtual machine

  • Some errors can be found in SMCore_<JobID>.log or SnapManagerWeb.log

Example1:

ERROR SMCore_336 PID=[6552] TID=[32] Unable to get storage details for VMDK.
UUID is not set for VMDK, check if disk.EnableUUID is set for the virtual machine
ERROR SMCore_336 PID=[6552] TID=[32] ErrorCode (-1), ErrorMessage (Unable to get storage details for VMDK. 
UUID is not set for VMDK, check if disk.EnableUUID is set for the virtual machine)
DEBUG SMCore_336 PID=[6552] TID=[32] DiscoverVirtualResources - Exit
DEBUG SMCore_336 PID=[6552] TID=[32] UpdateStorageFootprint - Enter
ERROR SMCore_336 PID=[6552] TID=[32] Invalid response object

Example2:

DEBUG SnapManagerWeb_486725 PID=[13496] TID=[86] Response Data: ****************************
_message Storage discovery failed, received error during operation: java.lang.ArrayIndexOutOfBoundsException. 
Please refer to operation logs for more details.
WARN SnapManagerWeb_486725 PID=[13496] TID=[100] Storage file system <MountPoint> is NOT associated with Windows filesystem resource.

Example3:

Verbose SDW PID=[2168] TID=[2604] ++CifsServerCache::Initialize
Verbose SDW PID=[2168] TID=[2604] No vserver is passed in.

Example4:

DEBUG SnapManagerWeb_486726 PID=[13496] TID=[47] Getting nsm object for resource <VMDK_MountPoint_Folder>
INFO SnapManagerWeb_486726 PID=[13496] TID=[47] StorageFileSystem count: 0
