# HG changeset patch # User Deepti B. Kalakeri <deeptik(a)linux.vnet.ibm.com&gt; # Date 1252950136 25200 # Node ID dec604e54eceb2c28f9dce3c9b22d87b152eb614 # Parent 10f8d110cd079ed7be6875efa0c65ea47e810cb5 [TEST] Added new tc to verify the RPCS error values for netfs pool. This test case verifies the creation of the StorageVol using the CreateResourceInPool method of RPCS returns an error when invalid values are passed. The test case checks for the errors when, Trying to create a Vol in a netfs storage pool. Tested with KVM and current sources on SLES11. Signed-off-by: Deepti B.
