portCfg --max-write-devs value Defines the maximum number of concurrent emulated tape write operations. As concurrency increases, the value of emulation decreases. Excessive concurrency has the potential to oversubscribe packet data memory. The setting has significance only for host (channel) initiated operations at this side and will not affect tape write operations initiated by hosts (channels) attached The default value is 16. The range is 1 to 32. --write-timer value Defines a time limit for pipelined write chains. This value is specified in milliseconds (ms). If a pipelined write chain takes longer than this value to complete, the ending status for the next write chain will be withheld from the channel. This limits processing to what the network and device can support. Too small a value limits pipelining performance. Too large a value results in too much data being accepted for one device on a path. The default value is 300 milliseconds (ms). The range is 100 to 1500. --write-chain value Defines the maximum amount of data that can be contained in a single CCW chain. If this value is exceeded, emulation is suspended. The default value is 3.2 MB (3200000 bytes) The range is 1 MB to 5 MB. --oxid-base value Defines the base value of an entry pool of 256 OXIDs supplied to emulation-generated exchanges. It should fall outside the range used by FICON channels and devices to avoid conflicts. The default value is 0x8000 (recommended setting). The range is 0x0000 to 0xF000. --ficon-debug value Defines optional debug flags. The default value is 0xF7C80000. This parameter is primarily for use by technical support personnel. Optional FCIP circuit arguments for fciptunnel create and modify include the following. -a | --admin-status [disable | enable] Enables or disables the circuit. Admin status is enabled by default. -S | --local-ip ipaddress | none Sets the local IP address to use for the circuit. The none option is supported only on the Brocade 7840 switch and the Brocade SX6 extension blade. -D | --remote-ip ipaddress | none Sets the remote IP address to use for the circuit. The none option is supported only on the Brocade 7840 switch and the Brocade SX6 extension blade. --local-ha-ip ipaddress | none Sets the local HA IP address to use for the circuit. This argument is applicable on the Brocade 7840 switch and the Brocade SX6 extension blade only. --remote-ha-ip ipaddress | none Sets the remote HA IP address to use for the circuit. This argument is applicable on the Brocade 7840 switch and the Brocade SX6 extension blade only. Brocade Fabric OS Command Reference 641 53-1004112-02
