The normal default value for this parameter is to select everything. Note This is not a command; rather, it is a common parameter to many commands. If you want to restrict the items to be tested to a smaller set, the parameter value is an item list with the following characteristics: • It is a comma-separated list of items. • Each item in the list might be a single element or a range of elements indicated by a "-" character and be mixed with individual values. • Spaces and tab stops are skipped. • Each item might be proceeded by an optional slot number and "/". For example, "0,3,4-6,1", "0,1,3,4,5,6", and "0 3 4 - 6 1" each select items 0, 1, 3, 4, 5, 6, and 7. Besides the syntax rules, there are also some grammatical restrictions on the slot numbers: • Once specified, a slot selection applies to all items to the right of the slot selections until the next slot selection or the end of the item list. For example, "1/0 - 15" and "1/0 - 1/15" are equivalent. • If no slot number is specified, user port lists are specified by area number. For instance, "0, 16, 32" and "1/0, 2/0, 3/0" specify the same ports on a 16-port/blade system. On that same system, "1/0, 16, 32" is not a valid list: even though it is legal syntax, the ports do not exist. • If no slot number is specified, all lists except user port lists will use the default slot 0. • No list type except for user port lists might specify multiple conflicting slot numbers. For instance, "1/0, 2/0, 3/0" is a valid user port list but is not valid for any other type of list. • In the case of conflicting settings within a single item list, an error is generated, as described earlier. In the case of multiple item list parameters, the last one on the command line overrides previous settings. The exact type of list varies, depending on the test and the parameter; however, the most common are Fabric OS Command Reference Manual Publication Number: 53-1000240-01 2-319
