The conventions for CLI syntax are as follows:

• Any parameter that is optional for the command syntax has a square bracket ([]) around it. For example:

  [-P] or [<rlink>]

• Required command words and parameters for the command do not have square brackets around them. For example:

  vxrlink or <rlink>

• Command words and parameters that are typed as shown in the command syntax are displayed in the Courier bold font, for example:

  vxrlink make or [-P]

• Parameters that the user needs to specify are displayed in Courier Italic font and have angle brackets around them. For example, <diskgroup_name>. They are placeholders for information the user is required to specify.

• The pipe (|) character is a separator that allows two or more choices for a given parameter. The user can use any one of the choices for the command. For example,

  [-f | -c <checkpoint> | -a]

• Help for any command is available if you type a hyphen followed by a question mark (-?) after the command. To view additional information about each of the parameters, type the command and the parameter followed by the -?. For example, vxrds addsec -? displays the information about the addsec parameter and the supported options.
