HP 4400 HP B-series Fabric OS 6.3.2d Release Notes (5697-1105, July 2011) - Page 51

CRC errors on internal links might occur on the HP 2408 24-10GbE w/8-8Gb FC Base FCoE and HP 2408 24-10GbE w/8-8Gb PwrPk+ FCoE Switches when jumbo frames are transmitted under certain traffic loads below the full line rate. If extensive CRC errors occur, traffic may stop completely and port disable/enable may be required to restore affected user ports. Fixed in Fabric OS 6.3.2b. Customers may be unable to upgrade from Fabric OS 6.2.0x to 6.3.x on an HP 4/256 SAN Director with an HP B-Series Multi-protocol Router Blade when a GE port is present and is persistently disabled. The CP could end up with an invalid configuration after attempting recovery by again downgrading to Fabric OS 6.2 and rebooting. This action could prevent the CP from successfully upgrading. Additionally, a good CP with a valid configuration that is HA synced with this CP could also be affected by the misconfigured CP. Workaround prior to upgrade: Enable all persistently disabled GE ports prior to the first upgrade. If a downgrade has already been performed, execute a configremove of the invalid configuration and download a valid configuration to restore the CP. Fixed in Fabric OS 6.3.2b. Switch Route (RTE) failures cause traffic issues or switch panics. Fixed in Fabric OS 6.3.2b. The supportshow/supportsave operations executed after a fastboot may cause SCSI timeouts to occur on the following switches: • HP 8/8 Base (0) e-port SAN Switch • HP 8/8 (8)-ports Enabled SAN Switch • HP 8/24 Base 16-ports Enabled SAN Switch • HP 8/80 Base 48-ports Enabled SAN Switch • HP 8/80 Power Pack+, 48-ports SAN Switch • HP 1606 SAN Extension Switch • HP EVA4400 embedded switch module, 8Gb Brocade • Brocade 8Gb SAN Switch for HP BladeSystem c-Class Class 3(C3) frame discards occur due to destination unreachable. However, since only a very small number of frames are dropped and the server retries SCSI traffic, users will not experience any functional impact. Fixed in Fabric OS 6.3.2b. In an AG fabric, DXFM/FM/SMI proxy switch sends a GAGI request to another switch in the fabric with Brocade_AG query. This sometimes triggers verify and floods the raslog, which may cause high CPU load and switch panic. Fixed in Fabric OS 6.3.2b. With Virtual Fabrics (VF) enabled and Radius server configured, customers may see RAS-1004 Software 'Verify' errors logged every 3 minutes on each VF on a switch being managed by DCFM or Web Tools. The errors fill the RASLOG and eventually cause an FFDC event in other system modules due to "too many open files". Virtual Fabrics can be configured on the following switches: • HP DC SAN Backbone Director Switch PP • HP DC04 SAN Director Switch • HP 8/80 Base 48-ports Enabled SAN Switch • HP 8/80 Power Pack+, 48-ports SAN Switch • HP 8/40 Base 24-ports Enabled SAN Switch • HP 8/40 Power Pack+ 24-ports SAN Switch Fixed in Fabric OS 6.3.2b. SW MIB counters such as Link Error State Block, Port Level Performance/Error, and other similar objects are available through CLI commands, but not through SNMP. Fixed in Fabric OS 6.3.2b.
