  • Review of the SnapDrive debug logs (Snpdrvdbg.log) located in the installation path for SnapDrive for Windows may reveal one or more of the following errors:

'The LUN may not have a File System created on it, or it may not be formatted with the NTFS file system. If it is a cluster system this situation can be caused by the LUN being offline, or not owned by this computer.'

'Failed to update virtual disk info on first pass, device path: '\?\mpio#disk&ven_netapp&prod_lun_c-mode&rev_0.3_#1&7f6ac24&0&383037416f2b494175346a32#{53f56307-b6bf-11d0-94f2-00a0c91efb8b}', lun path '/vol/volumename/lun_name', SCSI address '(X,X,X,X)', error code 0xc0040494, error description 'The LUN may not have a File System created on it, or it may not be formatted with the NTFS file system. If it is a cluster system this situation can be caused by the LUN being offline'
