1-7IntroductionParameterAlthough some commands have optional parameters, parametersare usually mandatory. You must place optional parameters aftermandatory parameters at the end of the command. For example,the array remove failover command has one requiredscsi_device parameter and additional optional scsi_deviceparameters: array remove failover {array}{scsi_device} [{scsi_device}...].As with switch values, parameters can be of only one type. Forexample, the array parameter can take only an integer value.All parameters are separated by blank space. A space can be usedin a parameter only within a quoted string.Blank SpaceBlank space is one or more spaces or tabs.Parameter and Switch Value TypesA parameter or switch value can be only one of several types.Simple value types include string, Boolean, and integer. Othervalue types include objects that can be manipulated, such as arrays(or arrays) and SCSI devices. This section explains the CLIparameter and switch value types.BooleanA boolean has a value of either TRUE or FALSE and can be specifiedwith any of the following key words: TRUE can be specified with TRUE, 1, ON, or YES. For switches,you can also specify TRUE by using the switch without anyswitch value. For example, /readonly and /readonly=TRUEare identical. FALSE can be specified with FALSE, 0, OFF, or NO. When aswitch is not specified, it takes the default value (usually,FALSE) specified in the switch description section of acommand. For example, open aac0 is the same asopen /readonly=FALSE aac0.
