ViPR Controller: Order to Remove an NFS file System Fails

[ERROR] Fri Jun 22 08:58:20 UTC 2018  Error 12000: Message: Operation failed due to the following error: Failure
Description: Check File System dependencies: NFS and CIFS exports and snapshots

ViPR Controller queries the VNX (CheckpointQueryParams XML API) to check for all snapshots on the entire array.

If SnapSure is not enabled or licensed on the VNX array, this causes the API query to fail. For example:

Time on CS: Mon Jun 18 18:12:50 CEST 2018
Output from: /nas/bin/nas_license -list
key                 status    value
site_key            online    57 93 7c 7a
cifs                online   
nfs                 online   
replicatorV2        online

SnapSure is a prerequisite for ViPR Controller in VNX file environments. See the ViPR Controller Virtual Data Center Requirements and Information Guide for more details. 

 

1. In the Unisphere UI, select the name of the Control Station.
2. Here, you get the full menu for the VNX cluster. On the left, you see the license submenu.
3. Verify if the SnapSure checkbox is checked. If it is, check that it is validated, and if it is not, validate it.

Before deleting the file system, ViPR Controller queries the VNX (CheckpointQueryParams XML API) to check for all snapshots on the entire array.
