HP StorageWorks 2/16V HP StorageWorks Fabric OS 5.2.0b Release Notes (AA-RWEYB - Page 18

• User is not informed with the IPSec mismatch RAS event when configuring a tunnel with IPSec mismatch on either ends. Fabric Merge Scalability Do not try to merge fabrics with conflicting domain IDs over a VE_Port. Before merging two fabrics over FC-IP with VE_Ports at each end, it is recommended that all domain ID and zoning conflicts are resolved. • Support for Default Zoning policies has been added to Fabric OS 5.1.0. Typically, when you issue the cfgDisable command in a large fabric with thousands of devices, the name server indicates to all hosts that they can communicate with each other. To ensure that all devices in a fabric do not see each other during a cfgDisable operation, you can activate a Default Zone with policy set to "no access". If Default zoning policies are enabled, all cfgEnable/disable commands and zoning changes must be run from a switch in the fabric running Fabric OS 5.1.0/5.2.0a. • In large fabrics with more than 1,000 ports, it is recommended that the MS Platform Database is disabled. It is also required that the Platform DB be disabled before downgrading to previous versions of Fabric OS. This can be done using the msPLMgmtDeactivate command. FRU insertion The FW_FRU_INSERTED message is displayed twice when a power supply FRU is inserted and powered on. There is no functional impact. System boot Not all Fabric OS services are available when the prompt becomes available during boot up. Wait for all the services to come up before using the switch or performing zoning actions. Performance Monitoring If the user tries to save more than 512 monitors using the perfCfgSave command, some of the monitors may be lost. Management - Proxy switches FCIP If you are using a Fabric OS 4.x switch as an API or SMI-S proxy to manage a 5.1.0 switch, you must be running Fabric OS 4.4.0d. • Frame drops observed on FCIP slow links: -The frame drops occur when the FCIP tunnel bandwidth is set to 10 Base-T (10Mbps), E1 (1.048Mbps), or T1 (1.544Mbps). -With E1 or T1, frames are dropped even without an impaired link. -With 10 Base-T, frame drops may be observed when a low impairment is put to the link. • portperfshow indicated incorrect (smaller) bidirectional throughput on the FCIP tunnel when Fastwrite/Tape Pipelining is enabled. • Fastwrite/Tape Pipelining did not inform user when it failed due to multiple equal paths configured on 2 GbE ports. • Backup jobs initiated from the Symantec BackupExec application slowed noticeably after adding significant IO traffic from regular hosts and targets to the FCIP tunnel. Port-based routing policy must be used for Tape devices. 18
