set host-parameters


Description	Sets controller host-port parameters for communication with attached hosts. Host ports can be configured as FC or iSCSI ports. FC ports support use of qualified 16-Gbit/s SFPs. You can set FC ports to auto-negotiate the link speed or to use a specific link speed. iSCSI ports support use of qualified 10-Gbit/s SFPs. iSCSI port speeds are auto-negotiated. 10GbE iSCSI host ports support use of qualified Direct Attach Copper (DAC) cables. iSCSI port speeds are auto-negotiated. CAUTION:Parameter changes will immediately take effect and may affect access to data. The exception is that attempting to change FC loop IDs requires restarting the controllers.

Syntax	To set FC port parameters: set host-parameters [controller a\|b\|both] [fibre-connection-mode loop\|point-to-point\|auto] [fibre-loop-id `values`] [noprompt] [ports `ports`\|all] [prompt yes\|no\|expert] [speed 4g\|8g\|16g\|auto] To set iSCSI port parameters: set host-parameters [controller a\|b\|both] [default-router `address`] [gateway `address`] [ip `address`] [iscsi-ip-version ipv4\|ipv6] [netmask `address`] [noprompt] [ports `ports`\|all] [prompt yes\|no\|expert]
Parameters	[controller a\|b\|both] Deprecated—use the ports parameter instead [fibre-connection-mode loop\|point-to-point\|auto] Optional. For FC, sets the topology for the specified ports to: loop: Fibre Channel-Arbitrated Loop (public or private). Loop mode cannot be used with 16-Gbit/s link speed. point-to-point: Fibre Channel point-to-point. This is the default. auto: Automatically sets the mode based on the detected connection type You must also specify the ports parameter. [fibre-loop-id `values`] Optional. For FC, specifies comma-separated loop ID values to request for host ports when controllers arbitrate during a LIP. Use this option if you want ports to have specific addresses, if your system checks addresses in reverse order (lowest address first), or if an application requires that specific IDs be assigned to recognize the controller. If the loop ID is changed for one port, the same ID is used for other ports in the same controller. If the ports parameter is specified, loop IDs are set based on the controllers that the ports are in. You cannot specify the same value for ports on different controllers. soft or 255: Soft target addressing enables the LIP to determine the loop ID. Use this setting if the loop ID is permitted to change after a LIP or power cycle. 0–125: Specify a hard target address if you do not want the loop ID to change after a LIP or power cycle. If the port cannot acquire the specified ID, it is assigned a soft target address You must restart affected controllers to make loop ID changes take effect. [default-router `address`] Optional. For iSCSI IPv6 only, the default router for the port IP address. This parameter requires the ports parameter. [gateway `address`] Optional. For iSCSI, the port gateway address. This parameter requires the ports parameter. [ip `address`] Optional. For iSCSI, the port IP address. Ensure that each iSCSI host port in the storage system is assigned a different IP address. This parameter requires the ports parameter. [iscsi-ip-version ipv4\|ipv6] Optional. Specifies whether to use IP version 4 (IPv4) or 6 (IPv6) for addressing controller iSCSI ports. When you change this setting, iSCSI-port address values are converted to the new format: ipv4: Lets you specify addresses in dot-decimal format, where the four octets of the address use decimal values without leading zeroes and the octets are separated by a period. For example, 10.132.2.205. The first octet may not be zero, with the exception that 0.0.0.0 can be used to disable the interface (stop I/O). This option is the default. ipv6: Lets you specify addresses using eight groups of four hexadecimal digits, where the groups are separated by a colon. All groups must be specified. For example, 0000:0000:0000:0000:0000:0000:0A90:3442 [netmask `address`] Optional. For iSCSI IPv4 only, the subnet mask for the port IP address. This parameter requires the ports parameter. [noprompt] Optional. Suppresses confirmation prompts. Specifying this parameter allows the command to proceed without user interaction. [ports `ports`\|all] Optional. Specific host port numbers or all ports. For port syntax, see Command syntax [prompt yes\|no\|expert] Optional. For scripting, this specifies an automatic reply to confirmation prompts: yes: Allow the command to proceed. no: Cancel the command. expert: Allow the command to proceed If this parameter is omitted, you must manually reply to prompts speed 4g\|8g\|16g\|auto Optional. For FC, sets a forced link speed in Gbit/s or lets the speed be auto-negotiated (auto). Because a speed mismatch prevents communication between the port and host, set a speed only if you need to force the port to use a known speed for testing, or you need to specify a mutually supported speed for more than two FC devices connected in an arbitrated loop. Loop mode cannot be used with 16-Gbit/s link speed. This parameter requires the ports parameter.
Examples	On a system with FC ports, set the link speed to 8 Gbit/s for ports A1 and B1. # set host-parameters speed 8g ports a1,b1 On a system with FC ports, set the link speed to auto for ports A1 and B1 and suppress the confirmation prompt. # set host-parameters speed auto ports a1,b1 noprompt On a system with iSCSI ports using IPv4 addressing, change the IP address of port A3. # set host-parameters ip 10.134.50.6 ports a3 On a system with iSCSI ports, specify to use IPv6 addressing and change the IP address and default router for port A1. # set host-parameters ports A1 iscsi-ip-version ipv6 ip ::8576:246a default-router ::0a0a:
