Description: Brocade recommends that users avoid upgrading any Brocade Fibre Channel product to Fabric OS v6.3.0, v6.3.0a, v6.3.0b, v6.3.0c or v6.3.1 due to issues identified in TSB 2010-075-A and TSB 2010-076-A.  For this reason, Brocade is removing these releases from the MyBrocade website.  For further details, review TSB 2010-075-A and TSB 2010-076-A at http://www.brocade.com/company/mybrocade.page or contact Brocade Customer Support at
