Info
Revision Table Version Date Details 2 13 March 2014 Updated to correctly indicate 7.2.0d as the 7.0.x version with the fix, not 7.2.0c. 1 13 February 2014 Original document release. An issue has been uncovered in which HP-branded B-series switches running Fabric OS (FOS) 7.2.0a, 7.2.0b, 7.2.0c, and 7.2.1 might encounter a condition where traffic is no longer able to be passed across E or F ports that exist within a user-defined logical switch. The issue is only seen on user-defined logical switch ports and may be seen as frames being corrupted or traffic flows appearing to stop on these ports. This issue only affects switches that have user-defined logical switches. Only ports within these user-defined logical switches will be susceptible to this issue. Ports within the default switch are not at risk, nor are any switches that do not have any user-defined logical switches configured. Switches running FOS versions earlier than 7.2.0 are also not at risk. When using Virtual Fabrics with user-defined logical switches on HP-branded B-series switches, do not upgrade to FOS 7.2.0a, 7.2.0b, 7.2.0c, or FOS 7.2.1. If 7.2.0a, 7.2.0b, 7.2.0c, or 7.2.1 has been installed on an HP-branded switch with user-created logical switches, complete the resolution immediately. If not, follow the resolution at your earliest convenience.
Scope
This issue affects HP-branded B-series switches that support Virtual Fabrics and are using user-defined logical switches on FOS 7.2.0a, 7.2.0b, 7.2.0c, and 7.2.1.
Resolution
This issue is resolved in FOS 7.2.0d, 7.2.1a (when available) or later FOS versions, refer to Brocade issue 491192. Upgrading to a FOS version that contains the identified fix will not only prevent this issue from occurring, but it will also clean up any impact previously caused by this issue. To upgrade to FOS 7.2.x, load FOS 7.2.0d, 7.2.1a (when available) or later firmware. If FOS 7.2.0a, 7.2.0b, 7.2.0c, or 7.2.1 has been installed on an HP-branded B-series switch, and it has been configured with Logical Switches: Do not create any new Logical Switches. Do not add any new devices to an existing Logical Switch. Upgrade to 7.2.0d, 7.2.1a or later. HP has removed FOS 7.2.0a, 7.2.0b, and 7.2.0c from its website in order to help prevent this issue. HP will continue to support customers who have already loaded one of these FOS versions but strongly recommends upgrading to 7.2.0d, 7.2.1a or later FOS version at the earliest convenience. Do not create or move ports to user-defined logical switches until after the upgrade is complete. HP supports FOS 7.2.1, but do not create or move ports to user-defined logical switches with this FOS version. Customers who use user-defined logical switches will need to use 7.2.0d, 7.2.1a or later FOS versions. If you have already upgraded to 7.2.1 and need the virtual switch fix prior to the availability of 7.2.1a, downgrade to 7.2.0d to get the fix. However, in this case, after the initial download, 7.2.0d must be downloaded a second time to fully activate the fix.
