separated by colons. Not all applications require this value, and some interface cards supply this value themselves by creating a number based on a transformation of the WWPN. WWPN (required) This is the worldwide port name for the FibreChannel device attached to the given port. It is a 64-bit EUI value represented in the field as eight hexadecimal bytes (using values 0-9 and A to F, and not preceded by 0x) separated by colons. Invalid addresses result in an error and the line is ignored. Boot-order (optional) This defines which target the interface uses during the boot process. Valid values are none, first, second, or both. If the value is first, second or both, the boot process tries to use the equivalent target to boot the blade (targets can have a priority of first or second). This parameter defaults to none. Here is an example of the FibreChannel entry parameters: //IP ,Type ,Slot ,Offset ,Port ,WWPN, ,Boot-order localhost ,fc ,1 ,0 ,3 ,2f:fc:00:00:c9:00:00:00 ,none v FibreChannel Target (FCTarget): In addition to the common parameters, the FibreChannel Target port entry also contains the following parameters. Priority (required) The value of this parameter can be first or second. first denotes the primary target for the blade and second denotes the secondary target. WWN (required) This is the worldwide node name of the target. LUN (required) This is the LUN of the target. For numbers less than four bytes long this can be specified as a decimal or hexadecimal number, where hexadecimal numbers are preceded by 0x. For longer numbers, you must use the standard EUI notation (eight pairs of hexadecimal characters, divided by colons). v Here is an example of the FibreChannel Target entry parameters: //IP ,Type ,Slot ,Priority ,WWN ,LUN localhost ,fctarget ,1 ,first ,00:00:00:00:00:00:00:00 ,0 Other format features of the configuration file The configuration file also contains the following characteristics and requirements: v Case: Characters in the configuration file are not case sensitive. v Whitespace: The file is largely whitespace agnostic. In general, whitespace is stripped before the fields are parsed. To make editing easier for you when you choose not to edit in a spreadsheet program, whitespace is added to the end of fields in the generated files. This whitespace is entirely optional and you can remove it at your discretion. v Newlines: The file supports spreadsheets that use the UNIX® line-feed only convention (OpenOffice Calc) and the DOS carriage-return/line-feed convention (Excel). It also supports line-feed only and carriage-return/line-feed text editors. v Line-length: The maximum line length is 512 characters. This in the absolute length of the line. It includes comments, whitespace carriage-returns, line feeds and other hidden characters. Exceeding this length results in a line error and the line is discarded. Chapter 7. Reference 47
