Failed to enumerate virtual disk

[SUPERSTRING]

Hello.

Started to receive this message every morning after adding new volume and creating a LUN on it.

Network drive successfully mapped and working in a cluster.

Couldn't find the answer by googling the error description. Could anyone help me please?

The problem disappeared after I've rebooted both cluster nodes.

Is this message showing up on all nodes of the cluster?

Is this message on the cluster node that is actively owning that disk resource?

1. No.

2. No.

Did you connect the disk via SnapDrive? Do both paths appear ok in the software for all cluster members?
