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).
v
logicalDriveSetName – The name of the set of logical drives on which you want to run the Enhanced
v
Remote Mirroring utility.
fileName – The name of a file, using characters and conventions that are appropriate for the system on
v
which the application is running.
storageSubsystemName – The label that you have assigned for a storage subsystem, as would be used in
v
the CLI to specify the name of the storage subsystem.
logicalDriveUserLabel – The label that you have assigned for a logical drive that uniquely identifies the
v
logical drive within the storage subsystem.
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.
The following items are considered syntax errors:
v More than one logSpec command in the input file
v Zero or more than one fileSpec attribute in a logSpec command (you must include exactly one
fileSpec attribute in the logSpec command)
v More than one timeoutSpec attribute in a logicalDriveSetSpec command
v Zero or more than one primarySpec attribute in a mirrorSpec command (you must include exactly one
primarySpec attribute in the mirrorSpec command)
v Zero or more than one secondarySpec attribute in a mirrorSpec command (you must include exactly
one secondarySpec attribute in the mirrorSpec command)
v Zero or more than one FlashCopySpec attribute in a mirrorSpec command (you must include exactly
one FlashCopySpec attribute in the mirrorSpec command)
Important: In the Enhanced Remote Mirroring utility configuration file, you must specify the primary
logical drive, the secondary logical drive, and the copy (FlashCopy ) logical drive. The utility does not
make sure that the secondary logical drive is correct for the Enhanced Remote Mirroring relationship. The
utility also does not make sure that the FlashCopy logical drive is actually a FlashCopy for the secondary
logical drive. You must make sure that these logical drives are correct. If the logical drives are not correct, the
utility will run, but the logical drives will not be consistent. For each mirror, the secondary logical drive
and the copy logical drive must reside on the same storage subsystem.
This example shows a configuration file for the Enhanced Remote Mirroring utility.
