In the VMM trace, the following errors are logged:

[4700] 125C.114C::10/03-21:57:43.604#04:Catalog.cs(621): !!! System.Data.SqlClient.SqlException: Cannot insert the value NULL into column 'ProtocolName', table 'RTMTP.dbo.tbl_NetMan_LoadBalancerVIP'; column does not allow nulls. INSERT fails.
[4700] The statement has been terminated. [4700] The statement has been terminated.


This can occur if the Brocade Load Balancer VIP only has the default protocol configured. The Brocade provider supplies NULL values for the protocol in a VIP during the refresh when only the default protocol is configured, thus causing a SQL VMM database exception.


To resolve this issue, define a protocol when creating a VIP in the Brocade Load Balancer.
