Topic Fabric Merge Scalability System boot Performance Monitoring Management-proxy switches Description 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 have 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.x or later. • 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. 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 If the user tries to save more than 512 monitors using the perfCfgSave command, some of the monitors may be lost. If you are using a Fabric OS 4.x switch as an API or SMI-S proxy to manage a switch running v5.1.0 or above, you must be running Fabric OS 4.4.0d, as a minimum requirement. 14
