SnapDrive for Windows fails to create Snapshots for LUNs on ONTAP 9.13.1
Applies to
- SnapManager for Hyper-V (SMHV) 2.1.4(P2)
- Snap Creator Framework (SCF) using SnapDrive for proper LUN support (4.3.x)
- SnapDrive for Windows (SDW) 7.1.5P5
- ONTAP 9.13.1
Issue
After upgrading ONTAP to 9.13.1, in SMHV and SMO, the backup fails, as SDW fails to create a snapshot.
The following events occur in the host's application event log (VSS events only for SMHV, since it uses it for consistency through the VMs):
SnapDrive error Event 194:
"Failed to create a consistent Snapshot copy({6ba5dba6-f922-4fbf-8b8a-d2c6a12ffee8}) of the LUN(s)
[\\?\Volume{dc82ceba-39cb-4e29-89b4-54f4fd283d02}\ ].
Error code : Failed to create Snapshot for LUN 'SFLAHYPERVCL02_csv03_vol'. Possible reason/solution:
Please verify the existence of LUN 'SFLAHYPERVCL02_csv03_vol' with Storage Path '/vol/SFLAHYPERVCL02_csv03_vol'.
If the LUN exists, retry the operation after some time.
