Virtual Storage Console: Traditional datastore provisioning hangs at 55%

Applies to

• Virtual Storage Console 9.7.1 and earlier
• Virtual Storage Console 9.8

Issue

During Virtual Storage Console's (VSC) datastore provisioning workflow, VSC is responsible for carrying out a number of tasks which include:

•    Creating a flexvol on storage
•    Reviewing export policy / rules
•    Initiating mount operation
 

When there are more than 20 unix users present in ONTAP:

• VSC creates a flexvol on storage
• VSC runs into an issue with the provisioning workflow before the mount operation is initiated
• A task called getUnixUsers (as seen in the kamino.log) starts but never completes. ZAPI calls are continuously issued to ONTAP and these events fill the kamino.log:
