In this syntax, items enclosed in double quotation marks (“ ”) are terminal symbols.
Items separated by a vertical bar (|) are alternative values (enter one or the other, but
not both). Items enclosed in curly braces ({ }) are optional (you can use the item zero
or more times).
These definitions are provided for non-terminals in the syntax:
 integer
– The timeout value must be an integer (decimal digits from 0–9).
 volumeSetName
– The name of the set of volumes on which you want to run
the Asynchronous Write Mode Mirror utility.
 fileName
– The name of a file, using characters and conventions that are
appropriate for the system on which the application is running.
 storageArrayName
– The label that you have assigned for a storage array, as
would be used in the CLI to specify the name of the storage array.
 volumeUserLabel
– The label that you have assigned for a volume that
uniquely identifies the volume within the storage array.
NOTE
Names and labels can be any characters that are defined as appropriate for your
operating system. The maximum length for a name or label is 30 characters. If the
name or label contains special characters (as defined by the operating system) or period
characters, you must enclose the name or label in double quotation marks (“ ”). You
can, optionally, enclose the name or label in double quotation marks at any time.
These items are considered syntax errors:

More than one
logSpec
command in the input file

Zero or more than one
fileSpec
attribute in a
logSpec

include exactly one
fileSpec



attribute in a
volumeSetSpec
command

Zero or more than one
primarySpec


Zero or more than one
secondarySpec


