HP 4400 HP B-series Fabric OS 7.0.0a Release Notes (5697-0881, June 2011) - Page 38

Miscellaneous • RASlog message AN-1010 may be seen occasionally indicating Severe latency bottleneck detected. Even though it is a Warning message, it is likely to be a false alarm and can be ignored. • POST diagnostics for the HP 8/40 Base 24-ports Enabled SAN Switch have been modified beginning with Fabric OS 6.3.1b and 6.4.0 to eliminate an INIT NOT DONE error at the end of an ASIC diagnostic port loopback test. This modification addresses BL-1020 Initialization errors encountered during the POST portloopbacktest. • It is important to note that the outputs of slotshow -p and chassishow commands also display the maximum allowed power consumption per slot. These are absolute maximum values and should not be confused with the real-time power consumption on 16 Gbps blades. The chassisshow command has a Power Usage (Watts): field that shows the actual power consumed in real-time on 16 Gbps blades. • Class 3 frames that have been trapped to CPU are discarded in the following scenarios on HP StorageWorks DC SAN Backbone Director Switch /HP StorageWorks DC04 SAN Director Switch/HP SN8000B 8-Slot SAN Backbone Director Switch and the HP SN8000B 4-Slot SAN Director Switch during the following conditions: • HA failover on HP StorageWorks DC SAN Backbone Director Switch /HP StorageWorks DC04 SAN Director Switch/HP SN8000B 8-Slot SAN Backbone Director Switch and the HP SN8000B 4-Slot SAN Director Switch platforms while running Fabric OS 7.0.0a or later firmware • Firmware upgrade from Fabroc OS 7.0.0a to a later release on HP 8/8 Base (0) E_Port SAN Switch, HP 8/40 Base 24-ports Enabled SAN Switch, and HP 8/80 Base 48-ports Enabled SAN Switch. • The QSFP information in the sfpshow output indicates the ID field as all zeros. This is as designed: ras080:FID128:root> sfpshow 5/32 QSFP No: 8 Channel No:0 Identifier: 13 QSFP+ Connector: 12 MPO Parallel Optic Transceiver: 0000000000000000 16_Gbps id • HP recommends that for directors with more than 300 E_Ports, the switch be disabled prior to executing the switchCfgTrunk command (used to disable or enable trunking on the switch). • During non-disruptive firmware upgrades, E_Ports in R-RDY mode may cause some frame drops on the E_Port links. • For the configure command, in Fabric OS 6.4, or later, the default value that displays for Maximum Logins per switch is different from the value that displays in Fabric OS 6.3.x. The default value has not changed; it was displayed incorrectly in Fabric OS 6.3.x, and is now corrected. • HP StorageWorks B-series switch Fill Word setting and link initialization command is no longer valid. With Fabric OS v7.0.0a, switches automatically determine the correct login sequence. • HP Network Advisor 11.1 is required for management of any switch running Fabric OS 7.0.0a. Since DCFM is unable to discover and manage switches running Fabric OS 7.0.0a, customers must upgrade from DCFM to HP Network Advisor prior to upgrading any switches to Fabric OS 7.0.0a. • The Fabric OS 7.0 Doc Update Document, which includes information on documentation updates, and is available on hp.com. • Instructions for changing the default setting in Fabric OS to accommodate the Avago watchdog timer are detailed in the Fabric OS 7.0 Doc Update Document. For a complete description on this process, see the document posted on hp.com. 38
