Doc Type:	Bug Fix
Doc Text:	Cause: During live merge, after deleting the snapshot (volume) we verify that the snapshot was indeed deleted. This verification is done by running GetVolumeInfo that presents an alert if the volume doesn't exist Consequence: Misleading alert indicating volume doesn't exist Fix: We added a support to specify expected errors when executing commands and if an expected error is returned, we don't display an alert. In this use case, we specify that we expect Volume Not Found Error Result: The alert is not displayed anymore when verifying that snapshot was deleted

This was a highly-visible (and annoying) customer-facing issue. Please add some doctext to explain what was going on here, and what was fixed.

Comment 3 Elad 2016-03-31 09:26:16 EDT

Snapshot live merge successful operation doesn't raise a "Volume does not exist" alert.
